Interstitial lung disease (ILD) and pulmonary fibrosis comprise a wide array of inflammatory and fibrotic lung diseases which are often confusing to general medicine and pulmonary physicians alike. The 2018 revised diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern published by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association has converged to a similar categorization of the HRCT findings into four groups. nonspecific interstitial pneumonia (NSIP), cryptogenic or-ganizing pneumonia (COP), acute interstitial pneumonia (AIP), respiratory bronchiololitis-associated interstitial lung disease (RB-ILD), desquamative interstitial pneumo-nia (DIP), and lymphoid interstitial pneumonia (LIP). Lung CT: Part 2, The interstitial pneumonias-clinical, histologic, and CT manifestations. J Cancer. When the chest radiograph shows a clear pattern of ILD or ALD, one can render a differential diagnosis on the basis of the pattern of parenchymal disease (Table 3.1). Interstitial lung disease (ILD) refers to a broad category of diffuse parenchymal lung diseases characterized by inflammation and/or fibrosis of the lungs. Impact of Interstitial Lung Disease Classification on the Development of Acute Exacerbation of Interstitial Lung Disease and Prognosis in Patients with Stage III Non-Small-Cell Lung Cancer and Interstitial Lung Disease Treated With Chemoradiotherapy. Radiographics. 5. In the updated American Thoracic Society–European Respiratory Society classification of the idiopathic interstitial pneumonias (IIPs), the major entities have been preserved and grouped into (a) “chronic fibrosing IIPs” (idiopathic pulmonary fibrosis and idiopathic nonspecific interstitial pneumonia), (b) “smoking-related IIPs” (respiratory bronchiolitis–associated interstitial lung disease and … For the radiologist, UIP is the classic also progressed leading to a new description and classification of premalignant and early lung cancer lesions. Imaging techniques are an essential component of the diagnostic process for interstitial lung diseases (ILDs). Founded in 1905 to combat TB, the ATS has grown to tackle asthma, COPD, lung cancer, sepsis, acute respiratory distress, and sleep apnea, among other diseases. Please refer to the articles in each specific etiology listed above for specific details on their imaging pattern. 6. 4. Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) of the lungs. CT-histologic correlation of the ATS/ERS 2002 classification of idiopathic interstitial pneumonias. Hypersensitivity pneumonitis (HP) is a complex fibroinflammatory lung condition that arises from repeated exposure, usually to aerosolised organic antigens, in sensitised individuals. The radiological appearances are not specific for the underlying cause of diffuse lung disease in many cases. As a part of this white paper, diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern were updated. Interstitial lung diseases classically produce the "3Cs": cough, clubbing of the nails, and coarse crackles on auscultation 6. Wells AU, Denton CP. Acute interstitial pneumonia (AIP, earlier named Hamman Rich Pneumonitis) is a rare idiopathic lung disease characterized by diffuse alveolar damage with subsequent fibrosis. Interstitial lung disease is considered a misnomer by some, as many of the diseases also involve the alveolar spaces. Wallis A, Spinks K. The diagnosis and management of interstitial lung diseases. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 28 (5): 1383-96. This chapter on interstitial lung disease (ILD) is followed by a chapter on alveolar lung disease (ALD). The sensitivity of any single CT sign in detecting CTD UIP was low (22.2–25.4%), though specificity was … Patients invariably present with dyspnea of varying time course and severity. The paper also states that all patients with an IPF diagnosis should have it reviewed at periodic intervals. Interstitial lung diseases associated with collagen vascular diseases: radiologic and histopathologic findings. The diffuse lung diseases tend to cause infiltrative opacification in the periphery of the lung, but patterns vary among the different etiologies. differential diagnoses of airspace opacification, presence of non-lepidic patterns such as acinar, papillary, solid, or micropapillary, myofibroblastic stroma associated with invasive tumor cells. The grading involves the following features of the disease: Feature Ferguson EC, Berkowitz EA. Cluster analysis modeling is a valuable tool in identifying distinct clinical phenotypes in heterogeneous diseases. Under category J 84.1 Other interstitial pulmonary diseases with fibrosis,several terms appear that are no longer used by clinicians, pathologists, or radiologists, for example, fibrosing alveolitis (cryptogenic), diffuse pulmonary fibrosis, and Hamman-Rich syndrome. 2. eCollection 2018. 3. Interstitial lung disease includes more than 200 different conditions that cause inflammation and scarring around the balloon-like air sacs in your lungs, called the alveoli. 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. 350: h2072. Radiological diagnosis of ILD is pattern-based and linked to underlying histology. Functional respiratory tests commonly show an abnormal restrictive pattern and reduced diffusing capacity. 2015;24:102-114. It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. 2018 May 22;9(11):2054-2060. doi: 10.7150/jca.24936. Radiographics.

However, radiography … The American Thoracic Society improves global health by advancing research, patient care, and public health in pulmonary disease, critical illness, and sleep disorders. 23 (5): 1057-71. Unable to process the form. Chest radiography is frequently the initial indicator of an ILD, and comparison of radiographs taken at different time points can show the rate of disease progression. In a recent cohort of a university hospital in Denmark, 431 cases of interstitial lung diseases were analyzed from 2003 to 2009. Interstitial lung disease in connective tissue disease--mechanisms and management. 2012;199 (4): W464-76. Interstitial lung disease (ILD) is a group of many lung conditions.All interstitial lung diseases affect the interstitium, a part of your lungs. Unable to process the form. Radiographics. Guo's clinical focus is on diseases of the lungs, including: interstitial lung disease, COPD, lung cancer, and diseases of the airways. Performance of CT Signs in Differentiation of Idiopathic Pulmonary Fibrosis From Connective Tissue Disease–Associated Interstitial Lung Disease in Patients With CT Findings of Usual Interstitial Pneumonia. AJR Am J Roentgenol. Adult patients with newly detected interstitial lung disease (ILD) of apparently unknown cause are clinically suspected of having idiopathic pulmonary fibrosis(IPF) if they have ... For comparison of the 2018 and 2011 diagnostic recommendations, see Table 1. Interstitial lung diseases are a group of diffuse parenchymal lung disorders associated with substantial morbidity and mortality. Lung damage from ILDs is often irreversible and gets worse over time. 2018 revised diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern, 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, absence of features suggesting an alternative diagnosis, the presence of this pattern, in the correct clinical setting, permits a confident diagnosis of, if the clinical setting is equivocal for IPF, lung biopsy and further review in a multidisciplinary meeting are recommended, reticulation with peripheral bronchiectasis or bronchiolectasis, the presence of this pattern, in the correct clinical setting, permits a confident diagnosis of IPF (idiopathic pulmonary fibrosis), evidence of fibrosis with some inconspicuous features suggestive of a non-UIP pattern, diagnosis of IPF cannot be reached and lung biopsy and further review in a multidisciplinary meeting are recommended, peribronchovascular predominance with subpleural sparing, predominant ground glass opacity without acute exacerbation, extensive mosaic attention with extensive sharply defined lobular air trapping on expiration.

Smoking-related interstitial lung disease: radiologic-clinical-pathologic correlation. Wittram C, Mark EJ, Mcloud TC. However, this approach has yet to be implemented in ILD. The scarring causes stiffness in the lungs which makes it difficult to breathe and get oxygen to the bloodstream. Diagnostic criteria for idiopathic pulmonary fibrosis: a Fleischner Society White Paper. The spectrum of conditions included is broad, ranging from occasional self-limited inflammatory processes to severe debilitating fibrosis of the lungs. 27 (3): 595-615. 1. Purpose of review . The scarring associated with interstitial lung disease eventually affects your ability to breathe and get enough oxygen into your bloodstream.Interstitial lung disease can be caused by long-term exposure to hazardous materials, such as asbestos. It is an approach formally endorsed in the 2013 ATS/ERS IIP classification statement and argued for in a recently published IPF Working Group statement [14, 19].
