anatomical compartments and their connections as demonstrated by ectopic air. Unilateral secondary spontaneous pneumothorax in a 69-year-old man with silicosis, and extensive emphysematous changes in lungs, with bullae. Axial CT scan depicts air spread in the mediastinum as a continuum space, and subcutaneous planes after percutaneous drainage of pneumothorax (chest tube not shown)
anatomical compartments and their connections as demonstrated by ectopic air. The same patient as in Fig. 2. Axial CT in the “lung window” depicts the thoracoabdominal continuum. a The anterior blending of the endothoracic and endoabdominal fascias outlined by air: one in the midline, between the two slips of sternal origin of the diaphragm on the back of xiphoid process, and two parasagittal between the sternal and costal origins of the diaphragm—the sternocostal triangles or foramen of Morgagni. b The crura have separated, forming the oesophageal hiatus. The subpleural space of the thorax and subperitoneal space of the abdomen are in continuity through the subserous space within the oesophageal and aortic hiatus
syndrome detected incidentally by asymptomatic bilateral pneumothorax in health screening: a case of a young Japanese woman. Chest CT showed right-sided pneumothorax and multiple cystic lesions in both of the patient"s lungs. Adhesion and thickened visceral pleura were found.
approach to cystic lung disease on HRCT. HRCT of a patient presenting with a pneumothorax (arrowhead). The only parenchymal abnormality was the presence of a few small cysts, such as the one in the posterior segment of the right upper lobe (arrow). The patient was later diagnosed with LAM
approach to cystic lung disease on HRCT. Coronal reformat CT thorax shows multiple thin-walled cysts with a lower lobe predominance in a patient with Birt-Hogg-Dube. The cysts have irregular shapes (arrow) and a right apical pneumothorax is present (arrowhead). The patient had a family history of pneumothoraces
approach to cystic lung disease on HRCT. Multiple cystic lesions are present in the left lung (arrow) with a small pneumothorax (arrowhead). The patient had a known history a previous oropharyngeal squamous cell carcinoma and the lesions were confirmed as cystic squamous cell carcinoma metastases
