摘要
目的孤立型细支气管肺泡癌患者CT影像表现及其不同病理基础对照研究。方法回顾分析本院2015年1月至2019年3月收治的41例孤立型BAC患者的临床资料。所有患者均经手术或病理学检查确诊。对患者所得MSCT图像以及其病理结果进行分析。结果病理:见患者的肿瘤颜色为灰白色,肿瘤质地为中等便硬,肿瘤周围边界清晰;肿瘤的生长方式为沿肺泡壁生长;根据MSCT检查可见,41例患者根据所得CT密度进行分型,其中39.02%(16/41)为Ⅰ型(单纯磨玻璃结节密度),41.46%(17/41)为Ⅱ型(混杂密度结节),19.51%(8/41)为Ⅲ型(单纯实性密度结节)。41例患者均为周围型,CT征象可见纯磨“玻璃征”、“环晕征”、“空泡征”或“空气支气管征”、“分叶征”、“毛刺征”、胸膜“凹陷征”、支气管血管“集束征”。结论MSCT检查可显示出孤立型BAC的病灶基础结构和周围特征,与病理对照研究一致性高,与其他肺癌相比BAC生长较为缓慢,预后情况也好。
Objective To compare the CT imaging features of patients with isolated bronchioloalveolar carcinoma and their different pathological basis.Methods The clinical data of 41 patients with isolated BAC treated in our hospital from January 2015 to March 2019 were retrospectively analyzed.All patients were diagnosed by surgery or pathology.The MSCT images of patients and their pathological results were analyzed.Results Pathology:The color of the tumor was off white,the texture of the tumor was medium and hard,and the border around the tumor was clear,the tumor grew along the alveolar wall.According to the MSCT examination,41 patients were typed according to the CT density,of which 39.02%(16/41)were type Ⅰ(simple ground-glass density nodules),41.46%(17/41)were type Ⅱ(mixed density nodules),19.51%(8/41)were type Ⅲ(simple solid density nodules).41 patients were of peripheral type.CT signs showed pure ground“glass sign”,“ring halo sign”,“vacuole sign”or“air bronchogram lobular sign”,“burr sign”,pleural“depression sign”,and bronchovascular“cluster sign”.Conclusion MSCT examination can show the basic structure and surrounding features of isolated BAC lesions,which is highly consistent with the research of pathological examination.Compared with other lung cancers,BAC grows slowly and the prognosis is also good.
