A 54-year-old man presented with a 3-month history of hemoptysis of approximately 50 ml per day. He had a remote history of pulmonary tuberculosis. On the second hospital day, he had an episode of massive hemoptysis. Dynamic and three-dimensional views of the pulmonary and bronchial vasculature on computed tomography obtained after the injection of contrast material demonstrated a large pulmonary aneurysm (Panels A and B, arrows). The patient underwent successful embolization of the pulmonary-artery aneurysm and its feeding vessel. However, the hemoptysis resolved only after subsequent embolization of the bronchial artery.
