摘　　要：回顾性分析了３９例纵隔淋巴结核的ＣＴ表现，并对部分手术病例做了ＣＴ－病理对照。病变多累及右侧气管旁和气管支气管区淋巴结。平扫密度均匀，部分可见斑点状钙化。增强扫描显示病灶内多发性小灶状相对低密度区或呈环状强化。与病理对照：病灶强化区为结核性肉芽组织，未强化部分多为干酪性坏死物。与其他纵隔淋巴结病变相比，淋巴结核的ＣＴ表现具有一定特征性。CT manifestation of 39 patients with mediastinal tuberculous lymphadenitis were retrospectively analysed. CT-pathologic correlation was made from 8 patients operationed on. Most of enlarged nodes was in the right peritracheal and tracheo-bronchial region, and showed homegeneous density on plain scans. Some of them showed mottling calcifications. Multifocal small areas of low density or thin enhancing rim on enhanced scans. CT-pathologic correlation revealed that the enhancing areas in enlarged nodes was tuberculous granulomas and that the areas of lower density were caseous necrosis. Compared with other common mediastinal lymphatic diseases, the CT manifeastations of mediastinal tuberculous lymphadenitis were some characteristic.
