Computed tomography manifestations of renal hemangiopericytoma.
Renal hemangiopericytoma (HPC) is a rare tumor. There are no unique radiological findings that can reliably aid in its preoperative diagnosis. A 60-year-old Japanese male was admitted for an abdominal mass. Ultrasound revealed a heterogeneous hyperechoic mass. Computed tomography (CT) showed a heterogeneous mass and tumor vascularity by a precontrast and dynamic study with maximum intensity projection (MIP) and volume-rendering technique (VRT). Radical nephrectomy was performed, and the histopathogic diagnosis revealed renal HPC.
