在一组回顾性研究中,4例证实为支气管肺泡癌(BAC)的患者检查发现薄壁囊状病变。尽管BAC 的这种表现文献少有报告,但在伴有实变的薄壁囊状病变的鉴别诊断中应包括BAC。BAC 可有不同的放射学影像,最常见的是孤立性周围肺结节、多发性结节及肺叶或弥漫性实变。4例患者中有2例胸片和CT 检查除肺叶实变外,还可见多发小囊状结节,大小6～11mm 不等,壁薄为1～2mm。活检示肿瘤细胞沿肺泡壁排列,证实为BAC,其中1例电镜检查为粘液型BAC。第3例3年前胸片
In a retrospective series of 4 patients with bronchial alveolar carcinoma (BAC) who were diagnosed with thin-walled cystic lesions. Although this literature has rarely been reported in BAC, BAC should be included in the differential diagnosis of thin cystic lesions with consolidation. BAC can have different radiological images, the most common is isolated solitary pulmonary nodules, multiple nodules and lobe or diffuse consolidation. In 4 patients, there were 2 cases of chest radiograph and CT examination in addition to solidification of the lobe. Multiple small cystic nodules were also found, ranging in size from 6 to 11 mm with a wall thickness of 1 to 2 mm. Biopsy showed that the tumor cells arranged along the alveolar wall, which was confirmed as BAC. One of them was examined by electron microscopy as mucinous BAC. The third case 3 years ago chest radiograph
