摘要
目的探讨肾门区局灶型Castleman病(LCD)的CT表现。方法回顾性分析5例经手术病理证实的肾门区LCD的CT和临床表现资料。结果病理分型为透明血管型4例,浆细胞型1例,肿块包膜完整。CT平扫表现为病灶边缘清晰锐利,略呈肾形、"双凸透镜"形或尖端朝向腹正中线的圆锥形软组织块影,均为单发,内见散在小斑点状钙化灶,1例病灶内还可见较宽的裂隙样低密度区。增强扫描透明血管型LCD除其中的1例裂隙样低密度区无明显强化外,余病灶实质部分均明显均匀强化,且有延迟强化的特点,浆细胞型LCD表现为轻中度强化。结论 CT对诊断肾门区LCD具有重要价值。
Objective To explore CT manifestations of localized Castleman＇s disease（LCD）in kidney hilar region.Methods The data of 5 patients with LCD in kidney hilar region proved pathologically were analyzed retrospectively.Results There were 4 hyaline-vascular type LCD patients and 1 plasma-cell type LCD,all had complete capsule.All lesions showed as isolated soft-tissue masses located in kidney hilar region with sharp edges on the plane CT scanning,with kidney-like or double-convex lens shape or cones,the tip pointing to the ventral midline.Spotted calcifications were seen in the lesions,and broader cleft hypodense area was also seen within one lesion.Significant uniform enhancement and enhancement in delay-scanning stage were found in all hyaline-vascular type LCD lesions,except the crack-like low density area in one patient,while mild or moderate enhancement was found in plasma-cell type LCD lesion.Conclusion CT is valuable for the diagnosis of localized LCD in kidney hilar region.
