支气管类癌的CT诊断

Diagnosis of bronchial carcinoid by computed tomography

目的探讨支气管类癌的CT表现,旨在提高对该病诊断准确性。方法回顾性分析经病理证实的12例支气管类癌的CT影像资料。结果 12例支气管类癌中,9例为中央型类癌,3例为周围型类癌;CT表现为圆形或类圆形影7例,不规则肿块影5例,边缘少见分叶、毛刺、胸膜凹陷征等;增强扫描病灶轻度强化3例,中度强化以上强化9例;5例可见"冰山征",合并钙化4例,囊变坏死1例,纵隔肺门淋巴结肿大2例,胸腔积液1例,所有病例均未见远处转移。结论 CT对支气管类癌诊断具有一定诊断价值,但确诊仍需活组织和病理学检查。

Objective To explore the CT findings of bronchial carcinoid,and improve the correct diagnosis of the disease. Methods CT imaging materials of 12 cases with bronchial carcinoid proved by pathology were retro-spectively analyzed. Results Of all the 12 cases,9 cases were central carcinoid,3 cases were peripheral carcinoid;By CT 7 cases had round-shaped or oval-shaped masses,5 cases had irregular masses,all the cases lacked with lobulation,spiculation,pleural indentation et al;by contrast,3 cases had mild enhancement,9 cases had marked enhancement;5 cases had iceberg signs,4 cases had calcifications,1 case had cystic change and necrosis,2 cases had enlarged lymph nodes in mediastinum,1 case had pleural effusions,all the patients had no distant metastasis. Conclusion The diagnosis of bronchial carcinoid has certain values by CT scanning,but the correct diagnosis still need biopsy and pathology.
