ABSTRACT
A 36-year-old woman complaining of bloody sputum and left-sided chest pain was admitted to our hospital. Dynamic contrast-enhanced chest computed tomography (CT) revealed both a non-enhancing mass in the left upper lobe and pleural effusion. Due to progressive anemia, it was diagnosed as a hemothorax caused by the mass rupturing. The left upper lobe mass was surgically resected and diagnosed as pulmonary vascular disease. Typical CT findings of the pulmonary arteriovenous malformation (i.e., a contrast-enhanced lesion communicating with a dilated pulmonary artery and vein) were not observed. Macroscopic findings revealed a thrombus in the mass. Thrombi might have ablated CT contrast-enhancement in the mass. This case represents a rare diagnosis of a hemothorax caused by non-enhancing pulmonary vascular disease.
