The first case of renal hemangiopericytoma presenting radiologically as a hypovascular mass is described. Preoperative diagnostic evaluation included ultrasonography, retrograde pyeloureterography, computerized tomography and angiography. Electron microscopy is helpful to distinguish this lesion from histologically similar juxtaglomerular cell tumors. Although renal hemangiopericytoma may appear benign on pathological examination it should be treated as a low grade malignancy and followed carefully.
本文描述了首例经放射学检查表现为少血管性肿块的肾血管外皮细胞瘤。术前诊断评估包括超声检查、逆行肾盂输尿管造影、计算机断层扫描和血管造影。电子显微镜检查有助于将此病变与组织学上相似的球旁细胞瘤相鉴别。尽管肾血管外皮细胞瘤在病理检查中可能看似良性，但仍应将其视为低度恶性肿瘤并进行密切随访。
