成人原发性肺结核的胸片与CT分析

The X-ray and CT analysis of adult-onset pulmonary tuberculosis

目的 分析成人原发性肺结核的胸片与 CT影像学所见 ,探讨其影像特征。方法 对资料完整并经临床确诊的 3 2例成人原发性肺结核 (其中原发综合征 2 2例 ,胸内淋巴结核 1 0例 )的胸片与 CT表现进行回顾分析。结果 在 2 2例原发综合征中 ,胸平片和 CT均能发现肺内原发灶 ,主要表现为大小不同斑片状阴影。而在淋巴结肿大中 ,CT均能发现 ,胸片仅发现 1 1例。淋巴结肿大的 CT主要表现为类圆形软组织肿块 ,以环形强化多见。结论 成人原发性肺结核有较典型的 CT表现 ,CT发现胸内淋巴结肿大明显优于胸平片 ,为临床诊断与鉴别诊断及治疗提供有价值的参考。

Objective To study the X-ray and CT imaging findings of adult -onset pulmonary tuberculosis, and to evaluate their imaging characteristics. Methods X-ray and CT images of 32 patients with the adult-onset pul monary tuberculosis(22 cases of primary tuberculosis, 10 cases of mediastinal t uberculous lymphadenitis),which had been confirmed,were analysed retrospectivel y. Results The X-ray and CT imaging findings of parenc hymal infiltration were found, and effectively show as patchy shadows with diffe r size, in 22 patients with primary tuberculosis.All patients with mediastinal tuberculous lymphadenitis were seen on CT, and 11 of 32 on chest fi lms. CT effectively showed soft tissue mass with round size, and that were conti nuous rim enhancement on contrast CT. Conclusions The adult-onset pulmonary tuber culosis has typical CT findings.CT imaging is superior to X-ray imaging in find ing mediastinal tuberculous lymphadenitis.It is valuable for diagnosis,different ial diagnosis and treatment to adult-onset pulmonary tuberculosis. <
