A 42 year-old male with a history of multidrug-resistant pulmonary tuberculosis suddenly developed massive hemoptysis. Embolization of a bronchial artery branch and the collateral systemic arteries did not resolve the recurrent bleeding. Spiral computerized tomography(spiral CT) of the chest showed contrast enhanced nodules within a large cavity at the left lower lobe in the arterial phase suggesting a Rasmussen aneurysm. A pulmonary angiogram showed abnormal vascular nodules at that site. Coils were deployed at both the proximal and distal vessels of this aneurysmal sac for embolization. Transcatheter arterial embolization is a safe and effective means of controlling bleeding from this pulmonary arterial pseudoaneurysm. Here we report a case of a Rasmussen aneurysm diagnosed by spiral CT, which was successfully treated by pulmonary arterial embolization with a coil.
