山雨欲来DepartmentofRadiologyWMC肺肿瘤分为：原发性和继发性。原发性又分为：良性和恶性肿瘤。良性肿瘤少见，恶性肿瘤中98%是支气管肺癌。DepartmentofRadiologyWMCDepartmentofRadiologyWMC右上中央型肺癌横S征DepartmentofRadiologyWMC左中央肺癌伴阻塞性肺炎DepartmentofRadiologyWMC右上肺癌伴不张DepartmentofRadiologyWMC左上肺癌伴不张；增强前后对比DepartmentofRadiologyWMC左上叶中央型肺癌上叶不张DepartmentofRadiologyWMC周围型肺癌DepartmentofRadiologyWMC分叶征：由于肿瘤各部分生长速度不均匀，或由于肿瘤在生长过程中受到血管、支气管的阻挡而造成的肿瘤表面凹凸不平。DepartmentofRadiologyWMC毛刺征：因恶性肿瘤向周围浸润生长，造成边缘模糊，形成自瘤灶向周围伸展的，无分支的细短线条影，呈毛刷状，称毛刺征。DepartmentofRadiologyWMC空泡征：瘤灶内未受肿瘤累及的正常含气的肺泡和扩张扭曲的细支气管表现为肿块影内点状、蜂窝状的低密度透亮影多见于直径<3cm的腺癌、鳞腺癌和细支气管肺泡癌DepartmentofRadiologyWMC胸膜凹陷征：一般认为系肿瘤的成纤维作用，即瘤灶内纤维瘢痕组织收缩，其收缩力通过瘤体邻近纤维网架传递到脏层胸膜面，将脏层胸膜拉近肿瘤内，凹入的胸膜与壁层胸膜之间构成空隙，内为生理性液体充填。凹入区肺组织形成沟槽，与凹陷的胸膜一起被周围膨胀的含气肺野衬托，表现为连接于胸壁与肿瘤之间的“Y”或“V”形细线条密影或喇叭状影，亦可称为“兔耳征”。DepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMC左上肺癌（分叶状）DepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMCDepartmentofRadiologyWMC右周围型肺癌分叶征DepartmentofRadiologyWMC左上肺周围型肺癌双上肺结核DepartmentofRadiologyWMC偏心性空洞
