Occupation-induced lung fibrosis.Subpleural sparing—an opacity-free, thin rim of parenchyma directly adjacent to the pleura in the posterior zones of the lung bases—hints at an underlying NSIP-pattern of lung injury and argues against the UIP-pattern.Typically seen as focal, non-segmental (typically crescentic) areas of parenchymal opacification, usually peripheral. Subpleural sparing seen on chest computed tomography (CT) imaging is characterized by pulmonary opacities sparing the lung peripheries abutting the pleura (typically 1cm and less from the pleural surface). Cellular nonspecific interstitial pneumonia .

NSIP Subpleural Sparing on HRCT

Subpleural pulmonary nodules are a location-based category of pulmonary nodules and are also often considered a type of perilymphatic nodule. The term “subpleural sparing” refers to computed tomography (CT) images that indicate that there is limited disease/infiltrate in the immediate subpleural location.normal aging 1: can be accompanied by subpleural cysts, independent of smoking history. After the evaluation of connective tissue disease, she was diagnosed as having systemic sclerosis-induced lung disease. Subpleural sparing seen on chest computed tomography (CT) imaging is characterized by pulmonary opacities . The term subpleural sparing refers to computed tomography (CT) images that indicate that there is limited disease/infiltrate in the immediate .

Interstitial Lung Abnormalities: What Radiologists Should Know

Subpleural lines (also known as pleural lines) refers to thin curvilinear opacities, 1-3 mm in thickness, lying less than 1 cm from and parallel to the pleural surface. In most cases, they abut the costal pleural surfaces directly, and to a lesser degree the diaphragmatic and mediastinal pleural surfaces. MATERIALS AND METHODS: In 29 children, the computed tomographic (CT) features of 40 lung contusions were reviewed for the presence of subpleural sparing. This observation is often associated with nonspecific interstitial pneumonitis and is a characteristic that distinguishes this pathology from usual interstitial pneumonitis (idiopathic pulmonary fibrosis). They can be subdivided int.

More common posteriorly and in lower lobes.Figures 2 and 3 demonstrate that true subpleural sparing can be confirmed by seeing the same degree of sparing on two different orthogonal views. It can have subpleural sparing with smaller contusions which can be a distinguishing feature.

The case shows the comparison between the normal lungs that the patient had, and the architectural distortion and formation of subpleural bands after COVID-19 infection, which persists even after the patient’s proven recovery. Due to the nonspecific imaging findings, lack of documented exposure history, and negative serologic evaluation, the patient underwent video-assisted thoracoscopic biopsy.
