目的　探讨Castleman病的CT表现特征。方法　 8例Castleman病患者均经手术病理证实 ,均有完整的临床、CT影像和病理资料。回顾性分析其CT和病理特征。结果　病理上包括透明血管型 7例和混合型 1例。CT扫描 7例表现为直径 5～ 15cm的单发巨大软组织肿块 ,1例为肝门区多发的球形病变 ,直径 1～ 4cm。平扫CT值 38～ 49HU(平均 44HU) ,增强扫描早期显著均匀强化 ,CT值高达 114～ 196HU(平均 133HU)。 3例伴有中央区分支状或点状钙化。 8例术前CT均误诊。结论腹部局限性Castleman病绝大多数表现为孤立的明显强化的或伴有中央分支状钙化的肿物 ,CT增强扫描对于明确诊断和临床分型具有重要意义 Objective To investigate the CT features of Castleman’s disease. Methods Eight cases of Castleman’s disease were confirmed by surgery and pathology. All of them had complete clinical, CT images and pathological data. The CT and pathological features were retrospectively analyzed. Results The pathology included 7 cases of clear vessel type and 1 case of mixed type. Seven cases of CT scans showed single giant soft tissue mass with a diameter of 5 ~ 15 cm, and one case was a spherical lesion with a multiple hepatic portal area with a diameter of 1 ~ 4 cm. CT scan 38 ~ 49HU (average 44HU), enhanced significantly enhanced early homogeneous scan, CT value of up to 114 ~ 196HU (average 133HU). 3 cases with central branch or punctate calcification. 8 cases of preoperative CT were misdiagnosed. Conclusion The vast majority of Castleman’s disease localized in the abdomen is isolated or significantly enhanced with central branch-shaped calcification. CT-enhanced scanning is of great significance in the diagnosis and clinical classification
