pediatric interstitial lung disease radiology

Appropriate Modalities in Suspected Interstitial Lung Disease. Every type of chILD has a unique cause or causes, all of which result in lung disease. It is therefore key to determine whether there is an underlying cause for the changes. Of the various IIPs, we spend the most time discussing usual interstitial pneumonia because it is the most common IIP and has the most detailed diagnostic criteria. Expiratory scanning is a useful adjunct to the inspiratory scan in the evaluation of patients with suspected small airways or obstructive lung disease. Note that the dependent lung is better inflated during the prone image (B) as opposed to the supine image (A), with decrease in atelectasis in the right lower lobe that manifests as mild diffuse ground-glass abnormality on the supine image (A). The bronchi often demonstrate an irregular or varicose morphology ( Fig. Chest radiography is one of the initial screening tests for ILD due to its wide availability, low cost, and low radiation exposure to the patient. Expected CT findings during expiration include an increase in lung attenuation, decrease in cross-sectional lung area, and reduction in airway size. Children 's interstitial lung diseases are rare diffuse lung diseases resulting from a variety of pathogenic processes that include genetic factors, association with systemic disease processes, and inflammatory or fibrotic responses to stimuli. Chronic interstitial lung disease in children Maria Aparecida S. S. Paiva,1 Sandra M. M. Amaral2 Abstract Objectives: To describe clinical and diagnostic features and the results of therapeutic conduct in a group of pediatric patients with chronic interstitial lung disease. CXR AP shows a branching bubbly appearance to the right lung and a large amount of air in the right pleural space. UIP represents the histopathologic pattern associated with idiopathic pulmonary fibrosis (IPF). Radiographics. In 2011 the American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Association published an evidence-based consensus statement on the diagnosis and management of IPF. The term interstitial lung disease is somewhat of a misnomer because many ILDs also involve the alveolar spaces. The spectrum of pediatric interstitial lung disease (PILD) includes a diverse group of rare disorders characterized by diffuse infiltrates and disordered gas exchange. 2. ■ Discuss the importance of temporal division of chILDinto infant and later childhood onset and of a sound understanding of pulmonary organogenesis and surfactant homeostasis in aiding radiologic diagnosis. Usual interstitial pneumonia (UIP) is a chronic fibrosing interstitial pneumonia in which there is a spatially and temporally heterogeneous distribution of normal lung, interstitial inflammation, fibrosis, and honeycomb change ( Fig. Two observers independently assessed chest … 2. However more recently the term idiopathic pulmonary fibrosis has been applied solely to the clinical syndrome associated with the morphologic pattern of UIP, with the specific exclusion of entities such as non-specific interstitial pneumonia (NSIP) and desquamative interstitial pneumonia (DIP) 1. Congenital "lung" lesions 1. 2002;22 Spec No : S151-65. The clinical evaluation of a patient with ILD includes a thorough… CXR AP shows a bubbly branching appearance to the right lower lobe and overall increased lucency throughout the entire abdomen. MATERIALS AND METHODS: We identified 20 infants, boys, and girls (age range, 1 month to 14 years) with histopathologic confirmation of interstitial lung disease. Abstract Interstitial lung diseases (ILDs) encompass a wide range of diffuse pulmonary disorders, characterized by a variable degree of inflammatory and fibrotic changes of the alveolar wall and eventually the distal bronchiolar airspaces. 1. Air trapping on expiratory HRCT has been shown to correlate with obstructive deficits on pulmonary function testing. Pediatric Chest Susan D. John Leonard E. Swischuk Abnormal Lung Opacity Pulmonary opacities in children are classified in the same way as in adults: as primarily alveolar or interstitial, focal or diffuse, and unilateral or bilateral. Other findings suggestive of an alternative diagnosis include pleural plaques (indicating possible asbestosis), dilated esophagus or distal clavicular erosions (indicating connective tissue disease), extensive lymph node enlargement, pleural effusions, and pleural thickening. Surfactant Deficient Disease 2. Ferguson EC, Berkowitz EA. In these rare disease communities there is a desire to add information obtained from images to registries. Pediatric chest 1. According to the 2018 updated guidelines, the features that are required to make a diagnosis of a UIP pattern on HRCT are (1) subpleural and basal predominant; distribution is often heterogeneous; and (2) honeycombing with or without peripheral traction bronchiectasis or bronchiolectasis ( Table 19.1 ). Eur J Pediatr 2015; 174:1123. The differential diagnosis for UIP consists of IPF (majority of cases in most clinics), connective tissue diseases, drug toxicity, chronic HP, and pneumoconioses. Chest radiography is one of the initial screening tests for ILD due to its wide availability, low cost, and low radiation exposure to the patient. 2. Although IPF is the most common cause of UIP, it is a diagnosis of exclusion and should only be made when other possible causes of UIP and ILD have been excluded. 3. 19.5 ). Fan LL, Langston C. Pediatric interstitial lung disease: children are not small adults. Considerations influencing the diagnostic approach include age at presentation, immunocompetence, chronicity, severity of disease, duration of illness, family history, and trend toward improvement. (B) Expiratory image demonstrates marked air trapping throughout the left lower lobe. 350: h2072. Imaging, particularly high-resolution computed tomography (HRCT), plays a pivotal role in the evaluation, diagnosis, and monitoring of ILD. Traction bronchiectasis represents bronchial dilation in areas of pulmonary fibrosis secondary to the traction effect of the fibrous tissue on the bronchial walls. Honeycombing is the most specific sign of fibrotic lung disease and results from alveolar disruption and dilation of bronchioles and alveolar ducts, with the creation of clustered, cystic air spaces lined by bronchiolar epithelium. Since its introduction over 30 years ago, HRCT has emerged as an indispensable diagnostic tool in the evaluation of patients with suspected ILD. During inspiration, the trachea maintains a round or elliptic shape. However, on prone scanning, the posterior subsegmental atelectasis resolves due to increased posterior lung aeration, whereas true subpleural disease remains visible ( Fig. AJR Am J Roentgenol. Six boys and girls without interstitial lung disease were also included. ILDs may occur in isolation or in association with systemic diseases. The updated document established four categories of HRCT patterns in patients with suspected IPF: (1) UIP; (2) probably UIP; (3) indeterminate for UIP; and (4) alternative diagnosis. 19.4 ). However, early manifestations of ILD are difficult to perceive on chest radiographs. In the extreme lung periphery of these patients, a dilated airway likely reflects traction bronchiolectasis. In the absence of honeycombing, pulmonary fibrosis can still be diagnosed by the presence of the other findings. Pediatric diffuse parenchymal lung diseases comprise a rare and heterogeneous group of chronic lung disorders characterized clinically by dyspnea, tachypnea, crackles, and hypoxemia and are associated with significant morbidity and mortality. Examples include: Where a cause is not determined, the idiopathic interstitial pneumonia (IIP) should be considered: Mnemonic: All Idiopathic Chronic Lung Diseases aRe Nonspecific. PubMed; CAS; Google Scholar; 4. de Jong PA, Nakano Y, Lequin MH et al (2003) Estimation of lung growth using computed tomography. Over time, pulmonary fibrosis causes progressive volume loss, which is manifested by crowding of bronchovascular structures in areas of disease involvement and retraction of the fissures. The pathogenesis of the various chILD is complex and the diseases share common features of inflammatory and fibrotic ch …. Often, HRCT demonstrates peripheral basal-predominant reticular and ground-glass opacities with traction bronchiectasis but without significant honeycombing, an appearance commonly associated with fibrotic NSIP ( Fig. Childhood interstitial (diffuse) lung disease in infants consists of a heterogeneous group of disorders previously classified with clinical, radiologic, and pathologic features. Unlike other ILDs, IPF does not respond to conventional corticosteroid and/or immunomodulator therapy. differential diagnoses of airspace opacification, presence of non-lepidic patterns such as acinar, papillary, solid, or micropapillary, myofibroblastic stroma associated with invasive tumor cells. Chronic lung disease (CLD) in children represents a heterogeneous group of many distinct clinicopathological entities. 19.2 ). Melly L, Sebire NJ, Malone M, Nicholson AG. UIP/IPF is the most common IIP, accounting for 50% to 60% of cases. MRI suboptimally images the lungs due to the inherent absence of proton density in the aerated lungs, as well as increased susceptibility artifact from extensive air–soft tissue interfaces. Bronchial Atresia 7. The mean cross-sectional area of the trachea can decrease by up to half of its area on inspiration. Ito Y, Akimoto T, Cho K, et al. It was commissioned by the ERS and critically presents progress made as well as drawbacks. And, even in cases of advanced ILD, it can be challenging to characterize radiographic findings and formulate a differential diagnosis. Patients invariably present with dyspnea of varying time course and severity. An official ATS/ERS/JRS/ALAT clinical practice guideline. Interstitial lung diseases classically produce the "3Cs": cough, clubbing of the nails, and coarse crackles on auscultation 6. Moreover, the cause of the patient’s symptoms may be due to obstructive lung disease rather than restrictive ILD. The standard HRCT protocol for ILD assessment includes an inspiratory scan with the patient in the supine position, an inspiratory scan in the prone position, and an expiratory scan in the supine position. The secondary lobule is the basic anatomic unit of pulmonary structure and function. Congenital Diaphragmatic Hernia 6. Kim EA, Lee KS, Johkoh T et-al. (2015) BMJ (Clinical research ed.). As mentioned previously, in patients with advanced ILD, prone images may be omitted because subtle dependent opacities no longer pose a diagnostic dilemma. Some abnormalities occur in a central or parahilar distribution, whereas others are predominantly peripheral or basal in location. Of these atypical UIP cases, the most common first-choice diagnoses based on HRCT were nonspecific interstitial pneumonia (NSIP), chronic HP, and sarcoidosis. The prevalence in the adult population was estimated in one study as ∼70 per 100,000 1, but the limited paediatric data in the literature would suggest it is at least two orders of magnitude less common in children. 28 (5): 1383-96. Congenital Lobar Emphysema 5. Attili AK, Kazerooni EA, Gross BH et-al. Diffuse lung disease (DLD), traditionally known as interstitial lung disease (ILD), consists of a diverse group of disorders that involve the pulmonary parenchyma and interfere with gas exchange. These findings, unfortunately, can mimic those of early lung ILD. Historically, terminology and classification of interstitial lung disease (ILD) in children have mirrored those of adult disease, but this is generally not helpful. The contributions of the European Respiratory Society Task Force on Interstitial Lung Disease in Children and the North American Children's Interstitial Lung Disease Group are reviewed, and a clinicopathologic classification of paediatric diffuse lung disease is summarized. However, in a busy clinical practice, these modifications to the HRCT protocol may prove to be challenging. Inspiratory (A) and expiratory (B) images from chest CT scans demonstrate the typical appearance of the trachea during different phases of the respiratory cycle. If honeycombing is absent but other features of UIP are present, the HRCT findings are best classified as a “probable UIP” pattern. During expiration, the posterior aspect of the trachea composed primarily of the trachealis muscle and connective tissue bows anteriorly. OBJECTIVE: We assessed the accuracy of thin-section CT and chest radiography to diagnose pediatric interstitial lung disease. MRI has limited utility in the evaluation of ILD. Read "HRCT in paediatric diffuse interstitial lung disease—a review for 2009, Pediatric Radiology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. PubMed; Article; Google Scholar ; 5. Please refer to the articles in each specific etiology listed above for specific details on their imaging pattern. CT-histologic correlation of the ATS/ERS 2002 classification of idiopathic interstitial pneumonias. Interstitial lung disease is considered a misnomer by some, as many of the diseases also involve the alveolar spaces. Subsegmental atelectasis is often present in the dependent lungs in normal individuals, appearing as dependent subpleural densities or lines. 19.7 ). HRCT features of pulmonary fibrosis include irregular pulmonary parenchymal interfaces, traction bronchiectasis and bronchiolectasis, regional volume loss, and honeycombing. ■ List the imaging features of the full spectrum of disorders in the 2013 American Thoracic Society chILDclassification system. There are often irregular interfaces at the edges of pulmonary vessels or bronchi, along the interlobar fissures, and along the peripheral pleural surfaces of the lungs. First, for rare lung diseases such as CF, primary ciliary dyskinesia (PCD), bronchiectasis and interstitial lung diseases, large global clinical networks and registries have been developed to improve our understanding and treatment of these diseases. In 2018, the same organizations published revisions of the original recommendations. On a Chest X-Ray it can be very difficult to determine whether there is interstitial lung disease and what kind of … Children with these conditions typically present with tachypnea, crackles, and hypoxemia. Pediatric radiology disease discussions including pediatric radiology cases. There is also evidence of pulmonary interstitial emphysema in the right lung. A characteristic histologic lesion is the fibroblastic focus, which represents an aggregate of proliferating fibroblasts and myofibroblasts. This brief review highlights publications in the field of paediatric interstitial lung disease as reviewed during the Clinical Year in Review session presented at the 2017 European Respiratory Society (ERS) Annual Congress in Milan, Italy. During inspiration, the trachea is typically convex throughout its margins and has an oval shape. Childhood interstitial lung disease can be difficult to diagnose. ■ Describe application of secondary lobular anatomy to interpretation of thin-se… 2012;199 (4): W464-76. During expiration, the trachea assumes more of a crescent shape as the membranous posterior wall bows anteriorly ( Fig. This does not necessarily mean that the diagnosis is not UIP, however, as there are a substantial number of cases that have an alternative diagnosis pattern on HRCT but are shown to have a UIP pattern on surgical lung biopsy and are eventually diagnosed as IPF. Park JS(1), Choi YJ(1), Kim YT(2), Park S(2), Chae JH(1), Park JD(1), Cho YJ(3), Kim WS(3), Seong MW(4), Park SH(5), Kwon D(5), Chung DH(5), Suh DI(1).

For example, a … Therefore, technically these studies are billed with the same code as a chest without The… ■ Discuss the importance of temporal division of chILDinto infant and later childhood onset and of a sound understanding of pulmonary organogenesis and surfactant homeostasis in aiding radiologic diagnosis. However, the prone and expiratory scans may be performed with individual axial scans at spaced (1–4 cm) intervals if radiation exposure is a concern. The radiologist reading these scans should make every effort to classify the HRCT findings as one of these four patterns. The process and pace of evaluation depend on several factors, and no single algorithm applies to the diverse clinical settings in which interstitial lung disease (ILD) can occur. First, because it is rare in children. For example, the prone scan may be omitted in patients without suspected ILD or with advanced lung disease. (A) Inspiratory image from high-resolution chest CT scan demonstrates relative hyperlucency and paucity of vessels of the left lower lobe compared to other portions of the lungs. 4. There is subpleural and basal predominant pulmonary fibrosis characterized by reticulation, traction bronchiectasis, traction bronchiolectasis, architectural distortion, and subpleural honeycombing. Functional respiratory tests commonly show an abnormal restrictive pattern and reduced diffusing capacity. However, due to the concern of cumulative radiation exposure in patients with chronic pulmonary disease, MRI has been used in lieu of CT at some centers to monitor certain patient populations. General Chest Without vs Interstitial Lung Disease vs High Resolution The only difference in the "Chest Without" and "Interstitial Lung Disease" protocols is the acquisition of expiratory images Expiratory images do not add anything to the billing side of things. On the other hand, obliteration of the tracheal lumen during expiration is diagnostic of flaccidity of the supporting tracheal cartilage, known as tracheomalacia. On HRCT there are four patterns: reticular, nodular, high and low attenuation (table). The HRCT protocol may be tailored to the clinical indication. Of these, reduction in airway size, particularly the trachea, is most useful in determining if the patient performed an adequate expiratory maneuver. DR. MOHIT GOEL JR1 18 SEPT. 2012 2. Radiographics. CT is the imaging modality of choice for the evaluation of ILD. After completing this journal-based SA-CME activity, participants will be able to: 1. 5. In the past, the term usual interstitial pneumonia was used synonymously with IPF. Axial (A) and coronal (B) images from high-resolution chest CT scans demonstrate the typical appearance of usual interstitial pneumonia pattern of pulmonary fibrosis. Although air trapping is not a prominent component of most ILDs, the presence of air trapping may occasionally aid in the differential diagnosis. 19.1 ). Interstitial lung disease (ILD) in children (chILD) is a heterogeneous group of rare respiratory disorders that are mostly chronic and associated with high morbidity and mortality. Honeycomb cysts typically share walls and occur in multiple layers, although early honeycombing may manifest as a single layer of subpleural cysts. CXR AP shows a branching bubbly appearance to the right lung. How is Pediatric Interstitial Lung Disease (chILD) diagnosed? We then describe the idiopathic interstitial pneumonias (IIPs), which are a subset of ILDs of unknown cause but with distinct clinicopathologic descriptions. Am J Respir Crit Care Med 2002; 165:1466. If your child has severe, frequent breathing problems or has had severe lung infections or serious lung problems, consult a pulmonologist. The radiological appearances are not specific for the underlying cause of diffuse lung disease in many cases. Supine (A) and prone (B) images of the right lower lobe from high-resolution chest CT demonstrate the relative difference in appearance of the dependent portion of the lung. Moreover, given recent US Food and Drug Administration (FDA) approval of medications shown to slow functional decline in IPF patients, accurate diagnosis is paramount. Honeycombing appears as clustered cystic air spaces with well-defined walls, typically subpleural in location. Interstitial lung diseases associated with collagen vascular diseases: radiologic and histopathologic findings. Also, subpleural sparing and bronchiectasis are much more evident on the prone image (B) than on the supine image (A). anti-Jo-1 antibody positive interstitial lung disease, interstitial pneumonia with autoimmune features, non-specific interstitial pneumonia (NSIP), respiratory bronchiolitis-interstitial lung disease (RB-ILD), desquamative interstitial pneumonia (DIP), combined pulmonary fibrosis and emphysema (CPFE), All Idiopathic Chronic Lung Diseases aRe Nonspecific, acute unilateral airspace opacification (differential), acute bilateral airspace opacification (differential), acute airspace opacification with lymphadenopathy (differential), chronic unilateral airspace opacification (differential), chronic bilateral airspace opacification (differential), osteophyte induced adjacent pulmonary atelectasis and fibrosis, pediatric chest x-ray in the exam setting, normal chest x-ray appearance of the diaphragm, posterior tracheal stripe/tracheo-esophageal stripe, obliteration of the retrosternal airspace, leflunomide-induced acute interstitial pneumonia, fibrotic non-specific interstitial pneumonia, cellular non-specific interstitial pneumonia, respiratory bronchiolitis–associated interstitial lung disease, diagnostic HRCT criteria for UIP pattern - ATS/ERS/JRS/ALAT (2011), diagnostic HRCT criteria for UIP pattern - Fleischner society guideline (2018)​, domestically acquired particulate lung disease, lepidic predominant adenocarcinoma (formerly non-mucinous BAC), micropapillary predominant adenocarcinoma, invasive mucinous adenocarcinoma (formerly mucinous BAC), lung cancer associated with cystic airspaces, primary sarcomatoid carcinoma of the lung, large cell neuroendocrine cell carcinoma of the lung, squamous cell carcinoma in situ (CIS) of lung, minimally invasive adenocarcinoma of the lung, diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH), calcifying fibrous pseudotumor of the lung, IASLC (International Association for the Study of Lung Cancer) 8th edition (current), IASLC (International Association for the Study of Lung Cancer) 7th edition (superseeded), 1996 AJCC-UICC Regional Lymph Node Classification for Lung Cancer Staging, autoimmune and collagen vascular diseases. Interstitial lung disease (ILD) is an umbrella term that encompasses a large number of disorders that are characterized by diffuse cellular infiltrates in a periacinar location. Mueller-mang C, Grosse C, Schmid K et-al. Lung CT: Part 2, The interstitial pneumonias-clinical, histologic, and CT manifestations. It is important to make the diagnosis of UIP because IPF has a poor prognosis, with a median survival of less than 5 years after the time of diagnosis. Posteroanterior and lateral chest radiographs are commonly ordered for patients with dyspnea. 6. Consequently, we recommend that expiratory scans be routinely acquired in every patient’s initial HRCT assessment. In fact, chest radiographs are … However, prone images can be valuable in detecting subtle or early ILD. To date, more than 150 ILDs have been described. A late presenter and long-term survivor of alveolar capillary dysplasia with misalignment of the pulmonary veins. Axial (A) and coronal (B) images from high-resolution chest CT scans demonstrate basal predominant pulmonary fibrosis in this patient with known nonspecific interstitial pneumonia characterized by ground-glass opacity, reticulation, and traction bronchiectasis. It is the smallest lung unit that is surrounded by connective tissue septa. Most of our knowledge about imaging findings in interstitial lung disease comes from HRCT. Bronchogenic Cyst 4. There are unique causes and presentations seen in infancy. A number of studies have shown that a UIP pattern on HRCT is highly predictive of a histopathologic UIP pattern. 3. Unable to process the form. Radiographics. An atypical HRCT appearance of UIP, either an indeterminate for UIP or an alternative diagnosis pattern on HRCT but a UIP pattern on histopathology, is fairly common. Background: Granulomatous and lymphocytic interstitial lung disease (GLILD) is a life-threatening complication in patients with common variable immunodeficiency (CVID), but the optimal treatment is unknown. More specifically, HRCT, in which images are reconstructed with thin sections and high spatial frequency algorithms, is recommended to image the lung interstitium optimally and characterize parenchymal abnormalities. If any of these features are present in a patient with suspected IPF, the HRCT findings should be classified as “alternative diagnosis,” and surgical lung biopsy should again be considered. In the setting of pulmonary fibrosis, traction bronchiectasis often takes on a varicoid pattern, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), Collagen Vascular Diseases and Vasculitis, Differential Diagnosis Based on Imaging Findings, Diffuse Lung Disease With Calcification and Lipid, Subpleural and basal predominant; heterogeneous distribution, CT features: cysts, marked mosaic attenuation, predominant GGO, profuse micronodules, centrilobular nodules, nodules, consolidation, Honeycombing with or without traction bronchiectasis/ bronchiolectasis, Reticular pattern with traction bronchiectasis/ bronchiolectasis, Subtle reticulation; may have mild GGO or distortion, Distribution: peribronchovascular, perilymphatic, upper or mid-lung, CT features or distribution of fibrosis that do not suggest any specific etiology, Other: pleural plaques, dilated esophagus, distal clavicular erosions, extensive lymph node enlargement, pleural effusions or thickening. In patients with suspected IPF who do not have identifiable causes of ILD, fulfillment of these HRCT criteria is diagnostic of IPF and obviates the need for surgical lung biopsy. Posteroanterior and lateral chest radiographs are commonly ordered for patients with dyspnea. The interpretation of interstitial lung diseases is based on the type of involvement of the secondary lobule. Although some of the conditions that cause DLD in children and adults are similar, they occur in different proportions in each population. AJR 174:549–554. The prevalence of CLD has increased in the past decade because of the more advanced and intensive respiratory support provided for compromised children and additionally the overall improved survival of preterm babies. Pediatric COVID‐19 studies have been mostly restricted to case reports and small case series, which have prevented the identification of specific pediatric lung disease patterns in COVID‐19. 27 (3): 595-615. For example, MRI surveillance of patients with cystic fibrosis has been well reported in the literature. 19.6 ). Radiographics. For example, the full-term newborn with respiratory failure is approached differently from the young child with tachypnea of insidious onset and … Honeycombing is critical to make a definitive diagnosis of a UIP pattern on HRCT. Eur Respir J 22:235–238. ■ List the imaging features of the full spectrum of disorders in the 2013 American Thoracic Society chILDclassification system. A number of precipitants can cause diffuse interstitial disease such as: Eliciting a history of underlying systemic disease is also helpful since they may involve the lungs in a diffuse and infiltrative manner.
