摘　　要：目的分析单纯性肾脂肪囊疝(SRACH)的CT表现并探讨其分型。方法回顾性分析18例SRACH的CT资料。结果18例均发生于左侧。SRACH可分为胸腔型及胸膜外型。17例X线平片为阴性,1例胸部侧位片表现为后肋膈角区丘状影。CT表现为脊柱旁或后肋膈区的圆形、椭圆形或梭形脂肪密度肿块,边缘光滑,病灶向下延伸至膈下并与肾周脂肪相连。结论MSCT可清晰显示SRACH的发生部位和疝囊的形态、大小、密度及与肾脂肪囊的关系,对其诊断有重要意义。Objective To explore CT features of simple renal adipose capsule herniation (SRACH)and discuss its classification. Methods CT data of 1 8 patients with SRACH were retrospectively analyzed.Results All of the 1 8 cases occurred on the left side. SRACH could be divided into two types,thoracic and extrapleural.XGray films were negative in 1 7 cases,and 1 case in the lateral chest radiograph showed the hilly shadow in the posterior costal phrenic area.The results of CT detections presented as round,oval,and fusiform fat density masses on the paraspinal or posterior phrenic angle area with smooth margins,which extended downward to the diaphragm and were linked to the perinephric fat.Conclusion MSCT can clearly show the location of SRACH,the shape,size and density of the hernia sac,and the relationship with the renal adipose capsule,which may be helpful in confirming the diagnosis.
