92-year-old female presents with dyspnea. Portable CXR in the frontal projection shows a well- defined line on the lateral aspect of the left lung masquerading as a pleural line and pneumothorax. Closer and magnified evaluation shows lung markings projecting beyond the sharp line
These findings are consistent with a diagnosis of pseudo-pneumothorax caused by a skin fold
