支气管类癌的CT表现

目的 总结支气管类癌的ＣＴ表现，提高对该病的认识。方法 回顾性分析２５例经病理证实的支气管类癌的临床和ＣＴ检查结果。结果 全组２５例中典型类癌１７例，不典型类癌８例。中心型１７例，其中起源于叶支气管８例，段支气管７例，主支气管２例；周围型８例。中心型类癌较小，直径０．５－３．２ｃｍ（平均１．９ｃｍ），边缘光滑，１例见瘤内钙化。

CTmanifestations of bronchial carcinoid tumors

Objective To analyze and evaluate the CT findings of bronchial carcinoid tumors Methods The clinical manifestation, CT findings, and pathological features were analyzed Results In our cases, 17 patients of bronchical carcinoids were typical, and 8 patients were atypical Ten patients had Cushing syndrome One patient had syndrome of inappropriate antidiuretic hormone Among 17 central tumors, sixteen nodules were smooth and round, the remaining one was irregular and lobulated The lesions ranged in size from 0 5 to 3 2 cm (mean 1 9 cm) CT revealed evidence of calcification in one of the 25 bronchical carcinoids The typical appearance of peripheral carcinoid was large solitary nodule with smooth margin or lobulated border The lesions ranged in size from 2 0 to 18 0 cm (mean 5 4 cm) CT revealed evidence of focal necrosis in 6 of the 8 peripheral tumors Conclusion Thoracic CT scan can be useful for localizing small bronchical carcinoid and hilar lymph node metastases Radiological diagnosis of bronchical carcinoid must be assessed in combination with clinical features
