分析了23名韩国患者的计算机断层扫描（CT），这些患者在胸部平片上表现为纵隔或肺门肿块，随后被发现患有结核性淋巴结炎。大多数患者是年轻人。X线平片上14例有肺结核表现。在CT上，所发现的结果是一个压倒性的优势，涉及右肺旁和气管支气管淋巴结。直径大于2cm的结节注射造影剂后，中心区多为相对低密度，边缘强化。强化壁的厚度通常不规则。一些较小的结节不显示低密度区，而是显示不同程度的均匀强化。虽然转移性淋巴结可以是低密度的，但本研究的经验表明，具有上述CT表现的年轻成人纵隔淋巴结病足以支持结核病的诊断。
An analysis was done of computed tomographic (CT) scans of 23 Korean patients who had presented with a mediastinal or hilar mass on plain chest radiographs and had subsequently been found to have tuberculous lymphadenitis. Most patients were young adults. Findings of pulmonary tuberculosis were seen on plain radiographs in 14 patients. On CT, findings were of an overwhelming preponderance of involvement of the right paratracheal and tracheobronchial nodes. After injection of contrast medium, nodes larger than 2 cm in diameter invariably showed central areas of relative low density and peripheral rim enhancement. Enhanced walls were usually irregular in thickness. Some smaller nodes did not show low-density areas, but instead showed varying degrees of homogeneous enhancement. Although metastatic nodes can be of low density, experience in this study suggests that mediastinal lymphadenopathy in a young adult with the CT findings described above is characteristic enough to support a diagnosis of tuberculosis.
