摘　　要：目的:探讨肺良性空洞性病变的CT影像学特征,讨论其诊断与鉴别诊断。方法:回顾性分析22例经病理或治疗证实的肺良性空洞的胸部X线正侧位平片和CT片(其中11例同时有CT强化扫描)。结果:22例均为单发结节空洞;空洞平均直径为26.5 mm;类圆形为主,占68%(15/22);空洞外形以浅分叶为主占64%(14/22);59%(13/22)是厚壁空洞;77%(17/22)的空洞内外壁均光整。73%(16/22)空洞壁CT增强幅度小于20 Hu。77%(17/22)空洞周围卫星灶明显。结论:良性肺空洞CT表现以内外壁光整的厚壁空洞为主,与恶性空洞的鉴别要点是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。Objective. To analyze the CT Imaging characteristics of lung benign cavity and discusI sing its diagnosis and differential diagnosis. Methods： The chest X ray films and CT scanning of 22 cases of lung benign cavities with pathology or operation confirmed were reviewed. All patients were done CT plain, while 11 of them were enhancement by contrast medium injection. Resuits： All 22 cases were of solitary pulmonary cavities. The average diameter of the cavities was 26.5mm. 68M （15/22）of the cavities was round or similar round. The majority of the cavities （64%,14/22） was less lobulated; 59%（13/22） was thick cavities and 77%（17/22） was smooth both in and outside the cavities. 73% （17/22） was less enhancement than 20Hu. 77%（17/22）cases along with satellite nodules. Conclusion： The lung benign cavities are majority thick cavities with mostly satellite nodules surround them. The important points for lung benign cavities differ- ent from malignant cavities are.. Are there any Satellite nodules along with the cavities？ lobulated or not？ the growth of CT enhancement of cavities before and after enhancement.
