摘要
目的探讨腹膜后纤维化(RPF)的CT和MR表现。方法对13例经病理证实的腹膜后纤维化的多层螺旋CT和MR表现作回顾性分析。结果腹膜后纤维化的CT和MR表现为腹膜后弥漫性斑块或肿块,多伴有肾积水和输尿管扩张,CT可呈低密度或等密度,增强后呈不同程度的强化,MRI上T1WI、T2WI呈低信号。结论腹膜后出现弥漫性软组织影或肿块样病变,合并肾脏及输尿管积水时,应考虑到RPF诊断。
Objective To discuss the CT and MRI findings of retroperitoneal fibrosis. Methods CT and MRI findings of 13 cases confirmed with retroperitoneal fibrosis by pathology were retrospectively analyzed.Results The CT and MRI findings of RPF included diffuse plaque or mass,hydronephrosis and dilatation of the ureters were often accompanied. The lesion could be hypodensity,inhomodensity or isodensity,and various enhancement by contrast administration. On MRI study,the lesion demonstrated hypointensity on T1 WI or T2 WI.Conclusions If a diffuse or mass lesion occurs in retroperitoneal space complicated with hydronephrosis or ureterlysis,RPF should be considered as the diagnosis.
