A 90-year-old man was admitted to the emergency room with acute right back pain. Immediate computed tomography (CT) scan demonstrated a large retroperitoneal hematoma and the presence of a ruptured 7-cm in diameter right internal iliac artery aneurysm. The patient subsequently developed rapid onset of hemorrhagic shock, which prompted an emergency operation. He made an uneventful recovery and was discharged on the 27th day after surgery without any problems. Isolated internal iliac artery aneurysms are rare but are dangerous and are associated with a high incidence of rupture and operative mortality. Repair of the aneurysms can be challenging, particularly in the face of rupture.

A 43-year-old woman was admitted with heart murmur. Transthoracic echocardiography (TTE) and aortgraphy revealed severe aortic regurgitation and also transesophageal echocardiography (TEE) and multi-row detector computed tomography (MDCT) demonstrated quadricuspid aortic valve. Combined cardiac surgery such as aortic valve replacement and replacement of the ascending aorta was successfully performed. Quadricuspid aortic valve is a rare anomaly. MDCT is a useful device for the morphological and functional evaluation of the aortic valve disease non-invasively.
