摘要
目的探讨周围型小肺癌的CT表现,以提高术前诊断正确率。方法回顾性分析58例经手术病理证实的周围型小肺癌的CT及相关临床资料。58例周围型小肺癌中包括鳞状细胞癌6例,腺癌13例,细支气管肺泡癌25例,黏液表皮样癌1例,混合性腺癌13例。结果CT扫描显示各种征象的发生率由高到低依次为:分叶征44例(75.9%),毛刺征40例(69.0%),血管集束征30例(51.7%),胸膜凹陷征30例(51.7%),空泡或空气支气管征24例(41.4%),磨玻璃征或晕征9例(15.5%)。增强后均有明显(≥20HU)不均匀强化。结论分叶征、毛刺征合并上述其他一项以上征象出现时提示周围型肺癌的可能性大。靶扫描可以提高显示小肺癌的CT征象。
Objective To study the CT findings of small peripheral lung cancer（SPLC） and to elevate the accuracy of preoperative diagnosis.Methods CT findings and their relatively clinical data of 58 patients with surgically and pathologically proven SPLC which comprised squamous cell carcinoma（n=6）.adenocarcinoma（n=13）,bronchioloalveolar carcinoma（n=25）,mucoepidermoid carcinoma（n=1） and mixed adenocarcinoma（n=13） were analyzed retrospectively.Results CT sanning showed that lobulation sign was found in 44 cases（75.9%）, spiculation sign in 40 cases （69%）,angiogram sign in 30 cases （51.7%）,pleural indentation in 30 cases （51.7%）,vacuole sign or air bronchogram in 24 cases（41.4%）and ground-glass opacity or halo sign in 9 cases（15.5%）.After the administration of contrast medium,the SPLC lesions appeared obvious enhancement（≥20 HU） and non-homogeneous enhancement. Conclusion The coexistence of lobulation sign and spiculation sign associated with any sign as mentioned above suggest SPLC likely.Target scanning can show more CT signs of SPLC.
