Castleman病的多层螺旋CT诊断

目的:总结Castleman病的多层螺旋CT(MSCT)表现,以提高对该病的认识和诊断水平。方法:收集经手术病理证实的Castleman病11例,回顾性分析其MSCT平扫和增强表现。结果:颈部1例,胸部6例,腹部4例。6例为局灶型,5例为多中心型。病理分型透明血管型9例,浆细胞型2例。病理上局灶性Castleman病多为透明血管型,平扫表现为较大的软组织密度影,可伴钙化和囊变,增强后中度至明显强化,强化方式与主动脉同步。多中心型Castleman病多为浆细胞型,病灶体积不大,表现为多个软组织结节,增强后轻至中度强化。结论:Castleman病的CT表现与病理类型密切相关,透明血管型的CT表现具有特征性。

Objective To summariaze the features of multi - slice spiral CT （MSCT） of Castleman＇ s disease.＂ Methods The pre - and post contrast MSCT featurs of 11 eases of Castleman＇ s disease comfirmed by pathology were retrospectively analyzed. Results there was 1 case in neck,6 cases in chest,and 4 cases in abdomen. There were focal type in 6 cases while diffuse type in 5 cases. Thcrc were hyaline - vascular type in 9 cases and plasma type in 2 cases pathologically, l,ocalized Castleman＇ s disease often showed large homogeneous soft tissue with calcification and cyst formation, and tumor had significant enhancement which was similar to the enhance model of aorta. Multicentrlc Castleman＇ s disease showed multiple soft tissue nodules and moderate to significant enhancement. Conclusion CT findings of Castleman＇ s disease were closely correlated with pathological subtypes. CT features of hyaline subtype are characteristic.
