Pancreatic Metastases from a Hemangiopericytoma of the Leg: A Case Report
نویسندگان
چکیده
originating from the pericytes of Zimmermann that are normally present in the basal membrane of the capillaries and postcapillary venules. The function of the pericytes is not well understood, although they appear to be involved in the regulation of vessel caliber. As all capillaries are enveloped by pericytes, hemangiopericytomas can be found virtually anywhere in the body (1, 2). However, this neoplasm more commonly affects the soft tissues of the extremities, pelvis, and retroperitoneum. Pancreatic involvement of a hemangiopericytoma is extremely rare. We report a case of a metastatic hemangiopericytoma involving the pancreas and its radiological findings on CT, MR imaging including MR angiography, endoscopic retrograde cholangiopancreatography (ERCP), and conventional angiography.
