目的:分析误诊肺门及纵隔淋巴结结核的CT表现,提高对该病的诊断水平。方法:分析13例肺门及纵隔淋巴结结核的临床及影像学资料。结果:13例肺门及纵隔淋巴结结核CT表现分为两种类型:(1)肺门肿块或结节灶并纵隔淋巴结肿大5例,表现为肿块或结节灶内部密度稍均匀;增强:不均匀强化3例,轻度不均匀分隔样强化2例。(2)单纯纵隔淋巴结肿大,8例共16个,表现为密度均匀,5个见斑点状钙化灶;增强:环状强化14个,轻度均匀强化2个。结论:仔细分析CT征象及结合临床资料特别是实验室检查,能降低肺门及纵隔淋巴结结核误诊率。
Objective: To analyze CT manifestations of misdiagnosed hilar and mediastinal lymph node tuberculosis and to improve the diagnosis of the disease. Methods: Clinical and imaging data of 13 cases of hilar and mediastinal lymph node tuberculosis were analyzed. Results: The CT findings of hilar and mediastinal lymph node tuberculosis were classified into two types: (1) hilar tumors or nodules with enlarged mediastinal lymph nodes in 5 cases, Inhomogeneous enhancement in 3 cases, mild uneven separation-like enhancement in 2 cases. (2) The mediastinal lymphadenopathy was simple, with a total of 16 in 8 cases, showing uniform density and 5 spots of calcified foci; enhancement: 14 annular enhancement and 2 mild homogenization. Conclusions: Careful analysis of CT findings combined with clinical data, especially laboratory tests, can reduce the misdiagnosis rate of hilar and mediastinal lymph nodes.
