ABSTRACT
From April 2009 to April 2017, we experienced on average 40 cases of spontaneous pneumothorax per year at our hospital, but we encountered only 2 cases of nontraumatic hemopneumothorax over the entire 8-year period. In one of these cases, we performed transcatheter artery embolization. Extravasation of contrast media was observed on CT near the apex of the lung, and angiography revealed the culprit vessel. We performed embolization and were able to achieve hemostasis and symptomatic improvement. However, hemopneumothorax recurred as a result of adhesion tear due to re-collapse of the lung and required surgical treatment. In this report, we describe our experience of this relatively rare condition and discuss the case with reference to the literature.
