目的探讨腹膜后纤维化(retroperitoneal fibrosis,RPF)的CT表现特点。资料与方法回顾性分析6例经病理证实为RPF患者的CT平扫和增强扫描图像特点。结果RPF CT表现为腹膜后弥漫性斑块或肿块及腹膜后脏器的受累,多伴有肾盂积水和输尿管扩张。结论腹膜后出现弥漫或肿块样病变合并肾及输尿管积水可作为CT诊断RPF的依据。

Materials and Methods Retrospective analysis of 6 cases of pathologically confirmed RPF patients with CT scan and enhanced scan features. Results RPF CT manifested as diffuse retroperitoneal masses or masses and retroperitoneal organs involved, mostly associated with hydronephrosis and ureteral dilatation.
