Abstract:
Objective:To investigate the characteristics of multi-slice spiral CT images in lung cancer with cystic lesions and improve the accuracy of diagnosis.Methods:The clinical data of 27 cases of cystic lung cancer confirmed by pathological results of surgery or puncture who received treatment during 2012-2019 in Tongde Hospital of Zhejiang Province, China were collected. The clinical stages, pathological results and the characteristics of multi-slice spiral CT images were analyzed.Results:All 27 cases were diagnosed with peripheral lung cancer. Type VI peripheral lung cancer occurred in 12 (44.44%) cases, and adenocarcinoma in 17 (62.96%) cases. Stage Ia lung cancer occurred in 18 (66.67%) patients. Above 70% of CT images showed irregular cystic structure [70.37% (19/27)], polycystic structure [74.07% (20/27)], and vessels passing through the cysts [70.37% (19/27). Over 90% of CT images displayed unsmooth inner wall of the cysts [92.59% (25/27)] and fuzzy margin of the cysts [96.30% (26/27)].Conclusion:It is very difficult to diagnose lung cancer with cystic lesions. This kind of atypical lung cancer should be considered when the imaging features of peripheral lung cancer appear including thickened cystic wall, fuzzy cystic margin, vascular bundle sign and pleural indentation sign.
