Retroperitoneal Hemangiopericytoma Parading as a Primary Renal Tumor

Retroperitoneal Hemangiopericytoma Parading as a Primary Renal Tumor Hemangiopericytoma is a rare perivascular tumor with only 40 cases reported to directly involve the kidneys. We report the case of a 57-year-old man that presented with an incidental left retroperitoneal mass that was intimately associated with the left renal hilum. Preoperative axial imaging failed to distinguish the true origin of the mass and the patient was taken to the operating room for left radical nephrectomy. The final pathology returned benign hemangiopericytoma. Preoperative imaging and clinical features make it difficult to predict this rare tumor type however the pathology and size of the tumor has important implications for long-term prognosis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Current Urology Karger

Abstract

Hemangiopericytoma is a rare perivascular tumor with only 40 cases reported to directly involve the kidneys. We report the case of a 57-year-old man that presented with an incidental left retroperitoneal mass that was intimately associated with the left renal hilum. Preoperative axial imaging failed to distinguish the true origin of the mass and the patient was taken to the operating room for left radical nephrectomy. The final pathology returned benign hemangiopericytoma. Preoperative imaging and clinical features make it difficult to predict this rare tumor type however the pathology and size of the tumor has important implications for long-term prognosis.
