目的探讨巨大淋巴结增生症（CD）的CT诊断价值。方法对经手术及病理证实的24例巨大CD的CT表现进行研究、分析。24例中，局限型透明血管型CD 23例、弥漫型CD 1例。结果24例CD，病变表现为圆形、类圆形或分叶状较大的单发软组织密度肿块影，边界多清楚锐利，直径3~15 cm。结论 CT平扫加增强扫描有助于对CD明确诊断和鉴别诊断，CD肿块以动脉期显著强化和延迟期的持续强化为特征性表现；胸、腹部局限型CD 以较大孤立性无坏死、出血肿物、均匀性明显强化、或中央伴有分支状钙化为特征。%Objective To investigate the effectiveness of CT in diagnosis of the Castleman's disease(CD). Methods Research and analysis were made on CT images of 24 patients who were confirmed through surgeries and pathology as CD sufferers. Among the 24 cases, 23 showed localized hyaline vascular-type CD and 1 diffuse type CD. Results Lesions in the 24 cases of CD showed the features of densified single soft tissue lumps in a round, round -like or lobulated shape with sharp and clear boundaries which were 3 to 15cm in diameter. Conclusion The Combination of the plain CT scan and enhanced scan played a supportive role in the accurate and discriminative diagnosis of CD. Characteristics of CD lumps were significant enhancement in the arterial phase and continuous enhancement in the delay period. Localized CD in chest and abdomen areas had the features of large isolated necrosis, bleeding mass, significantly enhanced uniformity or calcification in the central and branch areas.
