Abstract

Hemangiopericytomas are rare mesenchymal lesions arising from pericytes within the walls of capillaries. They often have an unpredictable course. We present a case of a large retroperitoneal hemangiopericytoma in a 65-year-old woman who initially presented with upper gastrointestinal discomfort. Following exptirpative surgery, pathology was consistent with hemangiopericytoma of low malignant potential. Widespread metastasis was discovered on follow up imaging, 17 months following surgery. To our knowledge, this is the first case report demonstrating a primary retroperitoneal hemangioperictoma with confirmed metastases.
