2021年1月7日 · CT findings include basilar and peripheral predominant ground-glass opacity and fine reticulation, with or without immediate subpleural sparing, and traction bronchiectasis. Fibrosis is typically homogeneous and symmetric, and traction bronchiectasis is often relatively central compared with that of usual interstitial pneumonia ( 52 , 53 ).

2006年12月24日 · Ground-glass opacity. Ground-glass opacity (GGO) represents: Filling of the alveolar spaces with pus, edema, hemorrhage, inflammation or tumor cells. Thickening of the interstitium or alveolar walls below the spatial resolution of the HRCT as seen in fibrosis.

2007年12月20日 · HRCT findings in Sarcoidosis. Small nodules in a perilymphatic distribution (i.e. along subpleural surface and fissures, along interlobular septa and the peribronchovascular bundle). Upper and middle zone predominance. Lymphadenopathy in left hilus, right hilus and paratracheal (1-2-3 sign). Often with calcifications.

2023年4月6日 · Diffuse or widespread ground-glass opacification/opacity can either manifest as diffuse ground-glass nodules or amorphous areas of diffuse ground glass. They can carry a wide differential diagnosis 1-3: diffuse alveolar disease. hydrostatic pulmonary edema. acute respiratory distress syndrome (ARDS) diffuse alveolar hemorrhage

2011年1月1日 · In the present study, pleural effusion, hydropneumothorax, chylothorax, pulmonary micronodular, macronodular and necrobiotic nodular lesions, pleural plagues, ground glass opacity and interstitial lung diseases were defined according to chest radiographs and computed tomography.

2023年10月1日 · Peribronchovascular distributions result from disease localized to the airways, vasculature, and/or lymphatics. Micronodules that are distributed in a peribronchovascular fashion are discussed further here: The following discussion applies to larger nodules or consolidations arranged in a peribronchovascular distribution.

2024年12月19日 · Ground-glass opacification/opacity (GGO) is a descriptive term referring to an area of increased attenuation in the lung on computed tomography (CT) with preserved bronchial and vascular markings. It is a non-specific sign with a wide etiology including infection, chronic interstitial disease and acute alveolar disease.

Slowly progressive high-resolution CT image through carina shows presence of ground-glass opacities with slight fine intralobular interstitial thickening. This combination of ground-glass opacities and interstitial thickening has been termed “crazy paving.”

ILD in RA can be secondary to the disease process, Disease-modifying antirheumatic drugs (DMARDS) use or both. ILD has been found to occur in 10% of RA patients but recent studies suggest prevalence of 27-67%, diagnosed by HRCT in asymptomatic individuals with RA ILD [1].
