A 73-year-old male was referred to our department for further treatment of a right retroperitoneal tumor. Contrast CT showed a tumor mass measuring 33 × 26 mm in size with poor contrast enhancement. Because we were unable to rule out tumor malignancy, we planned an operation. The tumor was easily separated and removed without nephrectomy. Histological study revealed a schwannoma. It is rare for this kind of tumor to arise from the retroperitoneum (approximately 0.7% of all cases), in particular at the renal hilum. We herein report a rare case of retroperitoneal schwannoma arising from the renal hilum.
一名73岁男性因右腹膜后肿瘤前来我院接受进一步治疗。增强CT显示一个大小为33×26mm的肿瘤肿块,增强效果不佳。由于我们无法排除肿瘤恶性的可能性,因此计划进行手术。肿瘤很容易分离并切除,未行肾切除术。组织学研究显示为神经鞘瘤。这种肿瘤起源于腹膜后(约占所有病例的0.7%),尤其是肾门处,较为罕见。我们在此报告一例罕见的起源于肾门的腹膜后神经鞘瘤病例。
