We report a case of hepatic artery aneurysm, which underwent preoperative three-dimensional CT for diagnosis. A hepatic artery aneurysm was incidentally detected with abdominal CT in a 65-year-old man who was receiving abdominal US check for liver cyst at regular intervals. Abdominal angiography could not reveal the vascular anatomy in detail. Therefore, three-dimensional CT and "cruising eye view" were employed for the definitive diagnosis and delineation of the detailed vascular anatomy. Lateral segmentectomy of the liver for liver cyst and reconstruction of the proper hepatic artery were performed safely. Hepatic artery aneurysms often become apparent with acute symptoms at rupture, and result in a high mortality rate (about 34%). Therefore, even if detected incidentally, they require treatment. In the selection of treatment strategy, detailed delineation of the vascular anatomy is indispensable. Three-dimensional CT and "cruising eye view" are very useful diagnostic modalities in treatment of hepatic aneurysms.
