The present case report describes a 44-year-old woman who presented with dyspnea due to diffuse interstitial lung disease. High-resolution computed tomography showed features of usual interstitial pneumonia, but the lung biopsy obtained by video-assisted thoracoscopy was consistent with a histological pattern of nonspecific interstitial pneumonia. Following the procedure, the patient developed progressive respiratory distress and died on postoperative day 13 with a clinical picture of acute interstitial pneumonia. The autopsy showed evidence of diffuse alveolar damage superimposed on the background pattern of nonspecific interstitial pneumonia. The present case report supports the notion that patients with a variety of subtypes of idiopathic interstitial pneumonias may be at risk of exacerbation of their underlying disease following thoracic procedures, including video-assisted thoracoscopic lung biopsy.

Introduction. Interstitial lung diseases include the entities of idiopathic pulmonary fibrosis, nonspecific interstitial pneumonia, cryptogenic organizing pneumonia, acute interstitial pneumonia, respiratory bronchiolitis-associated interstitial lung disease, desquamative interstitial pneumonia, and lymphocytic interstitial pneumonia. Recent introduction of high-resolution computed tomography has made the diagnosis of interstitial lung disease much easier. Usual interstitial pneumonia A predominantly subpleural reticulation and honeycombing at the basal posterior part of the lung with a progression to anterior and superior parts are characteristic of usual interstitial pneumonia/ idiopathic pulmonary fibrosis. Nonspecific interstitial pneumonia Typical findings of nonspecific interstitial pneumonia are bilateral, relatively symmetrical subpleural ground glass opacifications and irregular linear opacities. Desquamative interstitial pneumonia is characterized by diffuse symmetrical ground glass opacifications. Respiratory bronchiolitisassociated interstitial lung disease Centrilobular nodules and irregular ground glass opacifications are present. Cryptogenic organizing pneumonia Subpleural and peribronchial consolidations are prominent findings that are not present in other idiopathic interstitial pneumonias. Acute interstitial pneumonia. Bilateral ground-glass opacifications are present and areas of peripheral consolidations may also be seen in acute interstitial pneumonia. Lymphocytic interstitial pneumonia. Diffuse or patchy areas of ground glass opacification with centrilobular nodules and occasionally well-defined cysts are seen. Conclusion. Imaging plays a crucial role in identifying interstitial lung diseases but precise diagnosis requires a dynamic interdisciplinary approach that correlates clinical, radiological and pathologic features.

BACKGROUND Interstitial lung disease (ILD) is an unpredictable diffuse parenchymal lung disease, which involves interstitium of lung (tissue around the alveoli of the lungs). High resolution computed tomography (HRCT) is one of the confirmatory, easily accessible methodology for the conclusion and follow up assessment of interstitial lung disease. We wanted to study the normal HRCT patterns found with interstitial lung disease and contrastingly different HRCT designs and clinical information in differential determination of pulmonary fibrosis. We also wanted to study the different patterns of interstitial lung disease on high resolution computed tomography and thereby provide accurate diagnosis and management to the patients. METHODS The study was a hospital based prospective, cross sectional study. In the present study, total fifty patients referred from Department of Medicine and Department of Pulmonary Medicine of GCS Medical College having suspicion of interstitial lung disease were studied from April 2019 to September 2019. All patients underwent HRCT thorax on 16 slice Siemens computerised tomography (CT) scan machine in recumbent position utilising usual HRCT protocol. Lung abnormalities were noticed and classified for explicit diagnosis of interstitial lung pathologies. RESULTS Most of the patients (N = 25) were found to be in the age group of 50 - 80 years (17 female & 8 male). Progressive dyspnoea (N = 47; 94 %) was the most common chief complaint. The most common form of interstitial lung disease was usual interstitial pneumonia (UIN) (N = 18; 36 %) in our study. Acute interstitial pneumonia (AIP) (N = 7; 14 %) and non-specific interstitial pneumonia, NSIP (N = 7; 14 %) were the next common interstitial lung diseases. CONCLUSIONS The most well-known interstitial lung disease seen in our examination was usual interstitial pneumonia. Cases of interstitial lung disease are on the rise. Interstitial lung disease should be ruled out in all patients with progressive dyspnoea, particularly when there are no obvious or known causes of dyspnoea. Clinical and laboratory findings, pulmonary function tests, history of exposure along with HRCT workup is indispensable for the identification or exclusion of interstitial lung disease. HRCT is also useful for the follow-up study.

Lung Biopsies

Interstitial lung disease is a relatively frequent manifestation of systemic sclerosis with approximately one-third of patients developing clinical restrictive lung disease. Fibrotic nonspecific interstitial pneumonia is the most common cause of diffuse parenchymal lung disease in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), followed by usual interstitial pneumonia (UIP). Radiographic pleuroparenchymal fibroelastosis-like changes may accompany other forms of interstitial lung disease, most commonly UIP. In an appropriate clinical setting with supportive high-resolution computed tomography findings, lung biopsy is not needed to confirm the presence of interstitial lung disease and surgical lung biopsies are often reserved for atypical presentations. In this review, we discuss the histological findings that define the most common patterns of SSc-ILD and outline other findings sometimes encountered in lung biopsies obtained from systemic sclerosis patients, including pulmonary vascular changes, aspiration, chronic pleuritis, and diffuse alveolar damage.

Consensus Classification

According to the American Thoracic Society (ATS)/European Respiratory Society consensus classification, idiopathic interstitial pneumonias (IIPs) include several clinic-radiologic-pathologic entities: idiopathic pulmonary fibrosis (IPF), usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia, acute interstitial pneumonia, respiratory bronchiolitis-associated ILD, desquamative interstitial pneumonia, and lymphoid interstitial pneumonia. Ultrasound Lung Comets (ULCs) are an echographic chest-sonography hallmark of pulmonary interstitial fibrosis. We describe the ultrasound (US) findings in the follow-up of a NSIP’s case in rheumatoid arthritis (RA).

Abstract Background Usual interstitial pneumonia can present with a probable pattern on high-resolution computed tomography (HRCT), but the probability of identifying usual interstitial pneumonia by surgical lung biopsy in such cases remains controversial. We aimed to determine the final clinical diagnosis in patients with a probable usual interstitial pneumonia pattern on HRCT who were subjected to surgical lung biopsy. Methods HRCT images were assessed and categorized by three radiologists, and tissue slides were evaluated by two pathologists, all of whom were blinded to the clinical findings. The final clinical diagnosis was accomplished via a multidisciplinary discussion. Patients with a single layer of honeycombing located outside of the lower lobes on HRCT were not excluded. Results A total of 50 patients were evaluated. The most common final clinical diagnosis was fibrotic hypersensitivity pneumonitis (38.0%) followed by idiopathic pulmonary fibrosis (24.0%), interstitial lung disease ascribed to gastroesophageal reflux disease (12.0%) and familial interstitial lung disease (10.0%). In the group without environmental exposure (n = 22), 10 patients had a final clinical diagnosis of idiopathic pulmonary fibrosis (45.5%). Irrespective of the final clinical diagnosis, by multivariate Cox analysis, patients with honeycombing, dyspnoea and fibroblastic foci on surgical lung biopsy had a high risk of death. Conclusions The most common disease associated with a probable usual interstitial pneumonia pattern on HRCT is fibrotic hypersensitivity pneumonitis followed by idiopathic pulmonary fibrosis and interstitial lung disease ascribed to gastroesophageal reflux disease. In patients without environmental exposure, the frequencies of usual interstitial pneumonia and a final clinical diagnosis of idiopathic pulmonary fibrosis are not sufficiently high to obviate the indications for surgical lung biopsy.

The idiopathic interstitial pneumonias (IIPs) are a group of diffuse lung diseases that often manifest clinically with increasing dyspnea and hypoxemia. In the most recent revision of the American Thoracic Society/European Respiratory Society statement on IIPs, the major IIPs are divided into 3 groups: chronic fibrosing conditions (usual interstitial pneumonia and nonspecific interstitial pneumonia); smoking-related conditions (respiratory bronchiolitis and desquamative interstitial pneumonia) and acute/subacute IIPs (cryptogenic organizing pneumonia and acute interstitial pneumonia). Although some of these patterns may be seen with other conditions (e.g, NSIP with collagen vascular disease), the term IIP only refers to the idiopathic variants. Interestingly, the smoking-related conditions (RB-ILD and DIP) are included in this idiopathic grouping despite their association with cigarette use.
