摘　　要：目的探讨腹盆部Castleman’s病的CT、MRI特点。方法回顾性分析6例发生于腹盆部、经病理证实为Castleman’s病的影像学资料。6例均接受CT平扫及动态增强扫描,其中1例同时行MR平扫及动态增强扫描。结果弥漫型1例,CT表现为肝、脾肿大和多发肿大淋巴结。局限型5例,分别位于腹膜后(n=3)、肠系膜(n=1)、盆腔(n=1),CT平扫均表现为单发的类圆形或椭圆形软组织肿块,其中4例伴有"卫星"灶,2例病灶内可见点状、分支状钙化灶,3例病灶周围筋膜增厚;动态增强扫描动脉期显著强化,门静脉期及延迟期持续强化,强化方式与大血管相似,各病灶内部或周边可见增粗的血管影,其中4例动脉期病灶内可见星状或裂隙状低密度区,门静脉期及延迟扫描低密度区逐渐缩小。MRI检查1例,T1WI呈低信号,T2WI呈高信号,增强扫描强化特点与CT相似。结论腹盆部Castleman’s病少见,临床工作中容易误诊,但影像学上有一定的特征性表现有助于该病的诊断及鉴别诊断。Objective To analyze the CT/MRI features of Castleman＇s disease of the abdomen and pelvis. Methods CT/MRI images of 6 cases of pathologically confirmed Castleman＇s disease of the abdomen and pelvis were retrospectively reviewed. All the patients received plain CT scan and dynamic enhanced scan, and one had an additional MR scan.
