A lung cavity or pulmonary cavity is an abnormal, thick-walled, air-filled space within the lung. [1] Cavities in the lung can be caused by infections, cancer, autoimmune conditions, trauma, congenital defects, [2] or pulmonary embolism. [3] The most common cause of a single lung cavity is lung cancer. [4]
For example, the medical term pneumonia (noo-MŌN-yă) refers to a diseased state of the lung. There are two pleural membranes in the lungs. The visceral pleura is a thin membrane on the surface of the lungs. The parietal pleural lines the inside of the thoracic cavity.

5 Μαρ 2018 · A cavity, as defined by the Fleischner Society, is a gas-filled space, seen as a lucency or low-attenuation area, within a nodule, mass, or area of parenchymal consolidation. 3 It has a clearly defined wall > 4 mm thick. 2 Although any strict definition would be arbitrary, we suggest that acute and subacute cavities are those < 12 weeks old (acc...
A pulmonary cavity is defined as a gas-filled space within a zone of pulmonary consolidation or within a mass or nodule, often seen as a lucency or low-attenuation area. 1 Cavities are present in a wide variety of processes, such as lung cancer, autoimmune diseases, infections, congenital malformations and trauma.
The lung is encased in the thoracic cavity, a rigid structure that provides it with support and protection. The visceral and parietal pleura form the pleura cavity, which lines the lung parenchyma and inner aspect of the chest wall, respectively.
12 Ιαν 2021 · By definition, a cavity is an air-filled space forming within an area of pulmonary consolidation, mass or nodule, as a result of liquefication of the necrotic portion of the lesion and the discharge of this necrotic material via the bronchial tree.
