弥漫型肺泡癌的高分辨CT特征分析

目的 :回顾性分析弥漫型肺泡癌的高分辨CT(HRCT)表现特征。方法 :总结 12例经临床和病理证实的弥漫型肺泡癌HRCT表现。结果 :12例弥漫型肺泡癌可见磨玻璃影者 11例 ,实变 9例 ,多发结节 7例 ,“碎石路样”表现者 2例 ,其中 11例为混合表现。 6例有支气管气像 ,9例病变呈均匀或不均匀低密度 ,2例出现“血管造影征” ,2例伴少量胸腔积液 ,1例纵隔淋巴结肿大。结论 :弥漫型肺泡癌的HRCT表现多种多样 ,最常见的表现是多发结节、实变和磨玻璃影的混合影。HRCT片上出现实变和结节共存、伴磨玻璃影的小叶中心结节和远离实变的磨玻璃影时 ,则强烈提示弥漫型肺泡癌。

HRCT characteristics of diffuse bronchioloalveolar carcinoma

Objective:The purpose of this study was to analyze the HRCT features of diffuse bronchioloalveolar carcinoma.Methods:HRCT scans of 12 patients with pathologically proved diffuse bronchioloalveolar carcinoma were reviewed.There were eight women and four men,age ranging from 42 to 82 years.Results:HRCT findings of diffuse bronchioloalveolar carcinoma included ground-galss opacity (n=11),consolidation (n=9),multiple nodules (n=7),crazy-paving appea- rance (n=2),air bronchogram (n=6),low density area (n=9),CT angiogram sign (n=2),pleural effusion (n=2) and lymphadenopathy (n=1).Conclusion:Although these HRCT findings of diffuse bronchioloalveolar carcinoma are not specific,the combination of consolidation and nodules and the coexistence of centrilobular nodule and remote areas of ground-glass attenuation strongly indicate diffuse bronchioloalveolar carcinoma.
