摘要
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 2 5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 2 5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。周围型类癌较大 ,直径 2 0～ 18 0cm(平均 5 4cm) ,边缘光滑 ,瘤内常见坏死区。结论 胸部CT扫描对显示支气管类癌非常有价值 。
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
