炎症型细支气管肺泡癌的CT表现及病理分析

目的探讨炎症型细支气管肺泡癌的CT特征及其病理学对照。方法回顾性分析15例经支气管镜活检、经皮穿刺活检、开胸肺活检等病理证实的炎症型型细支气管肺泡癌的CT表现,评价其在CT诊断中的应用价值。结果 15例炎症型细支气管肺泡癌在CT上表现为实变影伴有磨玻璃影、磨玻璃背景上多发结节、蜂窝征、病理性支气管充气征、病理性血管造影征等多种混合征象,肺容积未见缩小;抗感染治疗病灶反而增大;无肺门、纵隔淋巴结转移,无或少量胸腔积液,无远处转移。结论肺炎型细支气管肺泡癌的影像学表现与病理过程有较一致的相对应关系。

CT Findings and Pathological Analysis of Pneumonic-Type Bronchioloalveolar Carcinoma

Objective To study the CT finding of pneumonic-type bronchioloalveolar carcinoma （BAC）, and to investigate CT imaging diagnostic value. Methods Retrospective analysis of 15 cases by bronchoscopy, needle biopsy and open lung biopsy confirmed the pathology, such as pneumonic- type bronchioloalveolar carcinoma of the clinical and pathological information, summing up its CT findings, evaluate its value in the CT diagnosis. Resu/ts 15 cases of pneumonic-type bronchioloalveolar carcinoma in the CT show that pulmonary segmental and pulmonary lobar consolidations with ground- glass opacities, ground-glass opacities and nodes, honeycomb sign, pathological bronchial inflatable sign, pathological angiography levy and other signs of mixed, lung volume not reducing, anti- infection treatment of lesions instead of increasing, without hilar and mediastinal lymph node metastasis, without or has a small amount of Neural effusion, no distant metastases. Conclusion Corresponding relation between imaging findings and pathologic course of the pneumonic-type bronchioloalveolar carcinoma is good.
