Rasmussen aneurysm is defined as a pseudoaneurysm resulting from erosion of the pulmonary artery at the tuberculous cavity. We present two patients with a Rasmussen aneurysm who presented massive hemoptysis. In one patient, an aneurysm was detected by pulmonary computed tomographic angiography, and the pulmonary artery proximal to the aneurysm was embolized using microcoils. Hemoptysis resolved after embolization and there was no recurrence. In another patient, the aneurysm was detected by arteriography. The pulmonary artery was embolized with a microcoil, and systemic collateral arteries were embolized using polyvinyl alcohol and gelatine sponge particles. Hemoptysis recurred one week after, but there was no recurrence of the aneurysm. Transcatheter embolization seems a safe and effective method for treatment of Rasmussen aneurysm.
