摘要
【目的】探讨单发性肺结核空洞的影像学表现。【方法】分析单发肺结核空洞患者87例胸片及27例CT检查的影像学特征。【结果】①结核空洞发生率为占肺结核的35.1%,其中单发肺结核空洞为22.5%。②单发肺结核空洞的影像学特征:多数结核空洞为厚壁空洞(79.3%),其壁可厚薄不均(82.6%),厚壁空洞的27.5%其内壁伴有壁结节,24.1%空洞出现浅液平面,空洞外缘7可模糊或伴粗长毛刺,可伴浅分叶,但不出现细小毛刺与深分叶征,全部病例可见卫星病灶,与引流支气管影。另外CT还显示2例空洞壁有钙化。【结论】肺结核空洞多为厚壁空洞,尤其是干酪厚壁空洞的影像学表现类似肺癌空洞,但前者不出现细小毛刺与深分叶征。出现卫星病灶、引流支气管影征、邻近肺叶或肺段支气管播散灶与空洞壁钙化是结核空洞的特征,对鉴别诊断有重要价值。
[Objective]To study the imaging manifestation of solitary pulmonary tuberculous cavity. [Methods] Eighty seven patients suffering from solitary pulmonary tuberculous cavity underwent chest X-ray, and 27 of them underwent CT scan. [Results]①The incidence of tuberculous cavity was 35.1%, and 22.5 of them were solitary pulmonary tuberculous cavity. ②Solitary tuberculous cavity imaging features： most of the tuberculous cavity （79.3%） were thick walled cavity, and the thickness was uneven （82.6%）. 27.5% of them were thick walled cavity with inner wall tubercle, and 24. 1% with a simple solution plane. The outer edge was empty or rough fuzzy barb with shallow sublobe, but without small and deep sublobe. All cases had satellite lesion and bronchial drainage shadow. In addition, CT showed that two cases had tuberculous cavity wall calcification. [Conclusion] Most kinds of the pulmonary tuberculous cavity are thick walled cavity. In particular, the image of the cheese thick walled cavity is similar to that of lung cancer cavitas. However, tuberculous cavity has no small and deep sublobe. Satellite lesion, bronchial drainage shadow, disseminated lesion of the neighboring lobes of the lung or bronchi segmentales and tuberculous cavity wall calcification are the characters of tuberculous cavity which are important for differential diagnosis.
