A pulmonary cavity is a collection of gas and/or fluid enclosed by a thick and often irregular wall which usually occurs when central necrotic tissue is expelled via a bronchial connection. Cavities may be single or multiple and can be isolated or associated with lung disease 12.
19 Νοε 2016 · The wall thickness of the cavitary lung lesions in solitary disease can be useful in differentiating between benign and malignant disorders. A recent study found that a wall thickness of less than 7 mm was highly specific for benign disease, and a thickness of greater than 24 mm was highly specific for malignant disease.
5 Μαρ 2018 · Cavities are found relatively frequently in primary lung cancer, with an incidence of up to 11% on plain chest radiographs 104 and up to 22% on CT scans. 105 Woodring et al 106,107 suggested that the maximum wall thickness of the cavity can help differentiate between malignant and nonmalignant causes, with a maximum wall thickness > 15 mm ...
The cavity wall thickness ranges from 3 to 6 mm. There is no lymphadenopathy or pleural effusion. Questions. What are the salient abnormalities shown in Figures 1 and 2? Based on the imaging findings, what should be included in the differential diagnosis? Considering the clinical presentation, what is the most likely diagnosis?
30 Σεπ 2019 · The cavity wall varies in thickness depending on the underlying pathology but typically measures at least 2 mm. Cysts, on the other hand, are usually thin-walled (<2 mm). Pathologically, a cavity arises from liquefactive necrosis and subsequent expulsion of debris via the bronchial tree.
