目的分析以含囊腔为主的周围型肺癌的CT影像表现,提高对此类病变的认识及早期诊断率。方法对24例均经病理证实的以含囊腔为主的周围型肺癌的CT表现进行回顾性分析,总结以含囊腔为主的周围型肺癌的CT影像特点。结果 24例患者中,男16例,女8例,年龄35~78岁,平均55.5岁,病理证实其中23例为腺癌,1例为鳞癌;22例为单发囊腔,2例为多发囊腔;囊腔形态4例类圆形,2例椭圆形,20例不规则形;16例囊腔内有分隔,11例囊腔有分叶,11例囊腔病变有毛刺,15例薄壁伴有壁结节,19例囊腔内壁不规则,7例囊壁规整,20例具有血管集束,18例有胸膜牵拉,12例囊腔周围伴有磨玻璃密度影,7例病灶相邻部分伴实性结节。结论以含囊腔为主的周围型肺癌的CT表现有一定特异性,尤其对含囊腔形态及周围的改变进行综合分析,可明显提高诊断率。
Objective To analyze CT images of peripheral lung cancer with cystic cavity and to improve their understanding and early diagnosis rate. Methods The CT findings of 24 cases of peripheral lung cancer with cystic cavity mainly confirmed by pathology were analyzed retrospectively. The CT features of the peripheral lung cancer with cystic cavity were summarized. Results Among the 24 patients, 16 were male and 8 were female, with a mean age of 55.5 years (range, 35-78 years). Of the 24 cases, 23 were adenocarcinoma and 1 was squamous cell carcinoma, 22 were solitary cysts and 2 were There were 4 cases of round type, 2 cases of oval shape and 20 cases of irregular shape. There were 16 cases of cysts and 11 cases of cysts. There were 14 cases of cyst lesions and 15 cases of cysts. In 19 cases, the internal wall of the cyst was irregular, and the wall of the cyst in 7 cases was regular. There were 20 cases of vascular bundles, 18 cases of pleural traction, and 12 cases of cyst density around the cysts. There were 7 lesions Adjacent part with solid nodules. Conclusion The CT findings of peripheral lung carcinomas, mainly cysts, are of certain specificity. In particular, the comprehensive analysis of cystic cavity morphology and surrounding changes can significantly improve the diagnosis rate.
