A 59-year-old man, who had had previous chest surgery, and who developed chest discomfort, cough, and bloody sputum, visited our hospital. Chest computed tomography revealed a mass with contrast media extravasation near to the upper lobe of his left lung, and there was no evidence of a pneumothorax. As a lung tumor, or hematoma, was suspected, he was transferred to a higher medical institution. Digital subtraction angiography of a branch of the costocervical trunk demonstrated abnormal vessels and contrast media extravasation. Transcatheter arterial embolization was, accordingly, performed. Based on the results of radiography and digital subtraction angiography, a spontaneous hemopneumothorax was diagnosed, and it was considered that the pneumothorax was not apparent as a result of adhesions in the thoracic cavity. It is necessary to consider a spontaneous hemopneumothorax when chest radiography reveals a mass in patients with a history of chest surgery accompanied by bloody sputum.
