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.},
