CT Feature of Castleman Disease and Relative Reference Reviewed

目的提高对巨大淋巴结增生症的CT表现的认识。方法分析5例经手术病理证实的巨大淋巴结增生病患者的CT表现,总结其特征。结果 5个病例中3例病灶位于肠系膜,2例位于纵隔。动态增强CT扫描,所有的病灶在动脉期明显强化,在延迟期均表现为持续强化。结论纵隔或肠系膜富血供的病变,在动脉期明显强化,延迟期持续强化,提示巨大淋巴结增生的诊断。

Objective To describe the most suggestive imaging feature of Castleman＇s disease, to improve the acknowledgement of it. Methods CT imaging materials of 5 patients with Castleman＇s disease were retrospectively reviewed, diagnosis of Castleman disease was done by surgery and pathology. Results In our series,the lesions were located 3 at the mesentery and 2 in the mediasfinum. At dynamic contrast CT scan,all lesions show marked enhancement after contrast administration at arterial phase and delay scan and the attenuation similar to aorta,calcification was seen in one patient. Conclusion Using proper CT technique,understanding the CT findings that the lesions at the mediastinum and mesentery showed marked contrastment at the arterial phase and delay scan, combining with clinical data,the suggestive diagnosis could be made.
