丝缕征——空洞型肺鳞状细胞癌的CT平扫特征

Silk-ray syndrome:CT scan characteristics of cavitary lung squamous cell carcinoma

目的探讨空洞型肺鳞状细胞癌CT平扫特殊征像及其在CT诊断中的诊断及鉴别诊断价值,以降低肺鳞状细胞癌的CT误诊率。方法回顾性分析50例经病理证实的肺鳞状细胞癌CT平扫表现,对其中16例空洞型肺鳞癌CT表现特征"丝缕征"及其病理基础及鉴别诊断进行了讨论。结果本组肺鳞状细胞癌CT平扫"丝缕征"发生率为22%(16/50),空洞内紊乱网格样结构出现于所有16例空洞型肺鳞癌病灶的CT平扫中。结论 "丝缕征"是空洞型肺鳞状细胞癌的CT表现特征。

Objective To explore the diagnostic and differential diagnostic value of CT plain scan in the diagnosis of pulmonary squamous cell carcinoma, and to reduce the CT misdiagnosis rate of lung squamous cell carcino-ma. Methods The CT manifestations of 50 cases of lung squamous cell carcinoma confirmed by pathology were ana-lyzed retrospectively, and the characteristics of CT manifestation, pathological basis and differential diagnosis of 16 cases of lung squamous carcinoma were discussed. Results The incidence of CT plain sweep ＂Silk-ray syndrome＂ in this group was 22%（16/50）, and the disordered reticulated structure appeared in all 16 cases of lung squamous cell carcinoma with CT scanning. Conclusion ＂Silk-ray syndrome＂ is the CT manifestation of lung squamous cell carcinoma.
