目的 回顾性分析肺结核空洞的CT影像学特征 ,以提高其诊断与鉴别诊断水平。方法 2 9例经病理或治疗证实的肺结核空洞。全部病例均进行了胸部X线正侧位平片和CT平扫 ,其中 19例同时有CT强化扫描。结果 2 9例均为单发结节空洞 ,95 % (2 7 2 9)位于两肺上叶 ;空洞平均直径为 2 3 .5mm ;以类圆形为主 ,占 73 % (2 1 2 9) ;空洞外形以浅分叶或无分叶为主 ,占 82 % (2 4 2 9) ;76%(2 2 2 9)是厚壁空洞 ;5 1% (15 2 9)空洞内外壁均不光整。空洞壁CT增强不明显。全部病例胸部X片均见有周围卫星灶。结论 结核空洞多表现为厚薄不均的空洞。空洞周围有无卫星灶、空洞外缘分叶的深浅及空洞壁CT强化的幅度是与其它空洞鉴别的要点
Objective To retrospectively analyze the features of CT images of pulmonary tuberculosis in order to improve its diagnostic and differential diagnosis. Methods Twenty-nine patients with pulmonary tuberculosis confirmed by pathology or treatment. All cases were performed chest X-ray plain film and CT plain scan, of which 19 cases also have CT enhanced scan. Results 29 cases were single nodules hollow, 95% (2 7 2 9) located in the upper lobe of both lungs; the average diameter of the hole was 23.5mm; mainly round-like, accounting for 73% (2 1 2 9 ). The shape of the hollow was dominated by shallow or no divisions, accounting for 82% (2 4 2 9); 76% (2 2 2 9) were thick-walled and hollow; and 5 1% (15 2 9) whole. Cavity CT enhancement is not obvious. All cases of chest X-ray are seen around the satellite stove. Conclusions The tuberculous cavity is mostly characterized by uneven thickness. Whether there is a satellite kitchen around the empty hole, the depth of the hollow outer edge of the leaf and the extent of CT enhancement of the hollow wall are the points to be distinguished from other holes
