多中心型Castleman病的CT诊断

CT diagnosis for multicentric type in Castleman's disease

目的:提高对多中心型Castleman病CT征象的认识。方法:分析3例经手术病理或穿刺活检证实为多中心型Castleman病的CT征象,总结其特征。结果:3例均为多中心分布,病理分型为浆细胞型1例,混合型2例。动态增强扫描病灶均表现轻度强化,延迟期表现为持续强化。结论:多中心型Castleman病的多病灶性分布,轻度强化及分枝状钙化等征象可提示该病的诊断,确诊需要靠穿刺活检及实验室检查。

Objective：To improve the recognition of CT imaging features of multicentric type in Castleman＇ s disease.Methods：To observe the CT imaging featares of 3 patients with multiple-center Castleman＇ s disease proven by surgery and pathology or biopsy.Results：All 3 cases were multicentricly distributed,the plasma cell type in the histopathology was faund in 2 cases and mixed type in 1 case.On dynamic contrast CT images,all of masses showed slight enhancement and sustained enhancement at delay.Conclusion：The symptom of multi-lesions distributed,slight enhancement and branch shape calcification could suggest the diagnosis of multicentric type Castleman＇ s.Its final diagnosis must be conbined with biopsy and laboratory tests.
