摘　　要：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。Objective To analyse the CT imaging characteristics of solitary pulmonary tuberculous cavity in order to improve its diagnosis level.Methods 29 cases of pulmonary tuberculous cavities comfirmed by pathology or operation.All the patients were underwent examination of contrast-enhanced CT.Results 29 cases were all solitary pulmonary cavities,93%(27/29) were located at the superior lobe of lung.The average diameter was 23.5 mm.73% of the cavities were round or similar round.The majority of the cavities (82%,24/29) were less or no lobulated;76%(22/29) were thick cavities and 51%(15/29) were less smooth both in and outside the cavities.The cavities were less enhancement.All cases along with satellite nodules.Conclusion The pulmonary tuberculous cavities are majority thick cavities.The important points for tuberculous cavities to diffierent from lung cancer and other disease cavities are:are there any satellite nodules along with the cavites,lobulated or not,the growth of CT enhancement of cavitied before and after enhancement.
