摘要
目的分析纵隔淋巴结核的多层螺旋CT特点,提高其诊断水平。方法回顾性分析8例经手术、穿刺活检或临床抗结核治愈证实的成人纵隔淋巴结结核的CT表现,其中,男2例,女6例,年龄17～65岁,平均35岁。结果8例均有不同程度纵隔或肺门肿大淋巴结,其中,3例平扫时淋巴结内呈不均匀低密度,增强扫描呈边缘环形强化。结论CT扫描,特别是增强CT扫描是确诊本病的首选方法。
Objective To analyze the CT features of mediastinal lymphoid tuberculosis in adults, especially, those on enhanced CT images so as to elevate the diagnostic level. Methods Eight patients（2 men and 6 women; aged 17-65 years; mean age, 35 years） with histopathologically or clinically proved mediastinal lymphoid tuberculosis underwent CT scans of the chest without and with contrast enhancement. The CT findings in all patients were analyzed retrospectively. Results On CT images, the enlargement of mediastinal lymphonodi or hilar lymphonodi in different extent was found in all patients. Of whom, 3 cases presented beterogencous low density in the inside of affected lymphonedi on pre - contrast images and rim circular enhancement of affected lymphonodi on post - contrast images. Conclusion CT scanning, especially enhanced CT scanning, is an optimal method for diagnosing mediastinal lymphoid tuberculosis in adults.
