摘　　要：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 。Objective To correlate the CT findings with the pathologic features of abdominal localized Castleman′s disease. Methods The patients were 5 men and 3 women, ranging in age from 17 to 46 years. The diagnoses were confirmed by surgery in all patients. The clinical, surgical, histopathologic records, and CT images were reviewed. Results Histopathologically, the hyaline-vascular type (n=7) and mixed type (n=1) were demonstrated. On CT scan, the lesions in 7 patients appeared as larger (5-15 cm in diameter), solitary, cylindrical soft-tissue masses with marked enhancement. One case was presented as multiple nodular lesions at hepatic hilum. Arborizing calcification was found in the central part of the lesions in 3 patients. Conclusion Most of the localized Castleman′s diseases in the abdomen manifested as solitary mass with marked enhancement or central arborizing calcification. Contrast-enhanced CT played an important role in the definite diagnosis and clinical classification.
