Traction bronchiectasis and honeycombing. HRCT enables evaluation of linear and reticular densities invisible on chest radiograms and even on conventional CT. Reticular opacities 1 to 3 mm thick, that cannot be characterized as representing one of these patterns, are often visible in patients with interstitial ... a limited subpleural reticular pattern was identified in the majority (24 of 40, 60%) of individuals older than 75 years, and was absent in a group younger than 55 years (p < 0.001) . A conundrum arises when widespread small opacities are difficult to categorize into one group or the other on chest radiography, or when ILD and ALD are both present. i have irregular ground glass and reticular opacities in both lungs without zonal predominance . – The typical imaging findings are reticular opacities and honeycombing, with a predominantly peripheral and basal distribution . Radiology. Ground glass opacities, referring to findings on computed tomography (CT) scans of COVID-19 patients, can diagnose coronavirus infections—but what exactly are 'ground glass opacities' in lung scans? This includes thickening of any of the interstitial compartments by blood, water, tumor, cells, fibrous disease or any combination thereof. Radiology. Acute Pulmonary Consolidation; … This term may sometimes be favoured in patients in whom biopsy is required to confirm the diagnosis. In chest radiology, reticular and linear opacification refers to a broad subgroup of pulmonary opacification caused by a decrease in the gas to soft tissue ratio due to a pathological process centered in or around the pulmonary interstitium. As the disease progresses, fibrotic changes develop in the form of traction bronchiectasis, volume loss, architectural distortion, and subpleural irregular reticular opacity . 2. This should be considered in the presence of basal subpleural reticular predominant abnormalities, where honeycombing is absent and where there is an absence of atypical features. 1. Post operative ileus ( mechanical obstruction vs p... Causative microbes in acute osteomyelitis. On pulse oximetry, SaO2 was 97% while breathing ambient air. A hallmark feature of NSIP on high-resolution chest CT scans is subpleural sparing; however, it is only seen in a few cases ( … Thoracic Imaging. Now after 4 months, she still had cough and shortness of breath. what does this mean to me ? Idiopathic pulmonary fibrosis (IPF), fibrosis associated with connective tissue disease, asbestosis, end-stage sarcoidosis or chronic hypersensitivity pneumonitis (HP) may present with lower zone, subpleural reticular pattern associated with honeycombing. ... n=30). Table 1. Ground-glass opacity, if present, is less extensive than reticular and honeycombing patterns. Centrilobular opacities: These are subtle ground glass opacities that are seen around the small airways and are mostly the result of inflammatory process around the respiratory bronchiole. 25 years experience Pulmonology. Dr. Sanjay Agarwal answered. The reticulation was fine or coarse, and was unassociated with honeycombing or … Case 2 : with NSIP + subpleural ground glass, conditions resulting in the NSIP type pattern. A 45-year-old member asked: what is bibasilar linear opacity in chest x-ray indicates?
