摘　　要：目的:探讨Castleman病的CT影像特征,以提高该病诊断准确率。方法:回顾性分析经病理证实的30例Castleman病患者的临床及CT数据,分析其CT影像学特征。结果:病理结果显示15例透明血管型、12例浆细胞型,3例混合型;局限型CD(unicentric CD,UCD)28例,多中心型CD(multicentric CD,MCD)2例。发病部位:28例UCD中位于腹腔16例(57%),其余部位12例(43%);2例MCD分别位于颈部、纵膈及腋窝、臀部。CT影像特点:所有病灶形态均规则;1例边界不清晰、周围脂肪间隙模糊;余病灶边缘清晰;13例UCD内见高密度钙化灶,其中点状钙化6例,粗大钙化5例,树枝状钙化3例;余病灶密度均匀,呈均匀等、低密度;增强扫描20例UCD病灶均匀强化,8例不均匀强化;11例UCD病灶动脉期明显强化、静脉期及延迟期强化减低;5例动脉期呈中度强化,静脉期及延迟期持续强化;5例UCD病灶可见粗大侧枝血管影;2例MCD病灶密度均匀,强化均匀。结论:Castleman病的CT表现具有典型影像学表现,掌握这些特征有助于提高该病的诊断能力。Objective:To investigate the CT features of Castleman’s disease and improve the accuracy of diagnosis.Methods:We retrospectively analyzed the clinical and CT imaging data of 30 patients with pathologically confirmed Castleman’s disease.Results:Surgical finding and pathologic results confirmed hyaline–vascular type in 15 cases,plasma-cell type in 12 cases and mixed type in 3 cases.There were 28 patients with unicenrtic CD(UCD)and 2 patients with multicentric CD(MCD).The lesions of 16 cases of 28 patients with UCDwere localized to the abdomen(57%)and 12 cases in other parts(43%).The 2 cases of MCD were found in neck,mediastinum,armpit and buttock.CT features:All lesions had regular morphology;there was 1 case with unclear boundary and others with clear edge;13 cases of UCD had calcification,including 6 cases of punctate calcification,5 cases of coarse and 3 cases of dendritic,and other cases had homogeneous equal or low density;on contrast-enhanced scan,20 cases of all UCD were homogeneous enhancement and 8 cases were heterogeneous enhancement;11 cases of UCDwere significantly enhanced in arterial phase and declined in venous phase and delayed phase;5 cases of UCDwere moderate enhanced in arterial phase and continuous enhanced in venous phase and delayed phase;5 cases of UCD found thick collateral vessels;2 cases of MCD found homogeneous density and homogeneous enhancement.Conclusion:The CT features of Castleman’s disease were typical.Mastering these features is helpful to improve the diagnostic ability of Castleman’s disease.
