Abstract
A 66-year-old female visited our hospital with chief complaint of left abdominal mass. Abdominal plain X-ray revealed left abdominal calcification and CT revealed a tumor located ventral to the left kidney. Dynamic CT showed that the tumor vessel was derived from the abdominal wall. Angiography revealed that the left inferior epigastric artery and the left deep iliac circumflexa artery feeded the tumor. On operation, the tumor was hanging from the anterior abdominal wall and resected with wide surgical margin. Histologically it was hemangiopericytoma.
Hemangiopericytoma is derived from the capillary pericytes. It has no specific clinical symptoms that makes preoperative diagnosis difficult. The tumor must be resected with wide surgical margin because of its histological dfficulty in differenciating benign hemangiopericytoma from malignant one.
