20例周围型肺癌影像学分析

The diagnosis and differential diagnosis of iconography in periphery bronchogenic carcinoma

目的探讨周围型肺癌影像学表现及其鉴别要点,进一步提高影像学对周围型肺癌的诊断。方法回顾性分析20例经手术病理证实的周围型肺癌患者的影像及临床资料,提出其诊断及鉴别诊断要点。全部病例均做了胸片及CT检查。结果周围型肺癌主要征象:(1)分叶征;(2)毛刺征;(3)胸膜凹陷征。次要影像学表现为:血管支气管集束征、空洞征、棘突征、空气支气管征及空泡征等。结论周围型肺癌有典型影像学表现,但肺部病变表现较复杂,故要注意鉴别诊断。

Objective To discuss the imaging findings of periphery bronchogenie carcinoma（PBC） and its differential diagnosis, so as to further improve diagnosising level of ieonography for PBC. Methods The imaging findings and the clinical data of 20 patients with PBC were retrospectively analyzed. The main point of diagnosis and differential diagnosis be proposed. Chest X-ray and CT inspection were performed in all patient with PBC. Results The main signs of PBC were ： （ 1 ） lobulated sign ; （ 2 ） burr sign ; （3） pleural indentation. The secondary imaging performance were：bronchial vascular convergence sign, cavity sign, air bronchogram sign as well as vacuolating sign, and so on. Conclusion PBC has the typical imaging features, but the performance of lung lesions is complex, therefore, attention should be paid to the differential diagnosis.
