目的探讨孤立型细支气管肺泡癌的特异性CT表现。方法分析30例经病理证实的孤立型细支气管肺泡癌患者的CT表现,记录并统计其征象。结果30例均为类圆形肿块,其中分叶征占33%、毛刺征占63%、胸膜凹陷征占63%、瘤内空泡征或空气支气管征占83%、磨玻璃样密度占53%、周围血管集束征占47%、增强后血管包埋征占21%。结论瘤内空泡征或空气支气管征、磨玻璃样密度、周围血管集束征、增强后血管包埋征为孤立型细支气管肺泡癌具有的相对特异的CT征象,有助于孤立型细支气管肺泡癌的诊断。
Objective To investigate the specific CT findings of isolated bronchioloalveolar carcinoma. Methods CT findings of 30 patients with pathologically confirmed isolated bronchioloalveolar carcinoma were recorded and recorded. Results All 30 cases were round lumps, of which 33% were lobulated, 63% were spiculated, 63% were pleural indentation, 83% were vesicular vacuole or air bronchial, and 53% were ground glass %, Surrounded by vascular bundles accounted for 47%, enhanced embedding after vascular embedding 21%. Conclusions The intratumoral vacuolization or air bronchus sign, the ground glass density, the peripheral blood vessel clustering sign and the enhanced embolism are relatively specific CT signs of solitary bronchioloalveolar carcinoma and contribute to solitary bronchioloalveolar alveoli Cancer diagnosis.
