A case of intrapelvic malignant hemangiopericytoma

Abstract

The patient was a 57-year-old male. From August 2010, he had discomfort with urination. Enhanced computed tomography (CT) showed an intrapelvic hypervascular tumor, 10 cm in diameter. Endoscopic ultrasound (EUS) and barium enema examination indicated that there was a giant tumor extrarectum, so a surgical resection was performed. Histological diagnosis was malignant hemangiopericytoma from retroperitoneum. Malignant hemangiopericytoma often recurs, therefore strict and long term follow up is necessary after the operation.
