A 70-year-old woman had undergone right S8+9 segmentectomy for stage I A lung cancer. Surgical staplers were used for an intersegmental line. Two years after surgery, routine chest computed tomography(CT) showed a 40-mm mass around the staple line in the right lower lobe, and positron emission tomography (PET) was positive. The mass was suspected to be local recurrence of lung cancer, and she was done additional surgery for resection of the remaining right lower lobe. The pathologic diagnosis was lung nontuberculous mycobacteriosis. It was suggested that nontuberculous mycobacteriosis developed at the atelectasis around the staple line. In addition to local recurrence, the possibility of nontuberculous mycobacteriosis should be considered in cases of pulmonary nodules appearing at the staple line after pulmonary resection.
一名70岁女性因I A期肺癌接受了右S8+9段切除术。手术吻合器用于段间线。术后两年，常规胸部计算机断层扫描（CT）显示右下叶吻合线周围有一个40毫米的肿块，正电子发射断层扫描（PET）呈阳性。该肿块怀疑是肺癌局部复发，她接受了额外手术以切除剩余的右下叶。病理诊断为肺非结核分枝杆菌病。提示非结核分枝杆菌病在吻合线周围的肺不张处发生。除了局部复发外，肺切除术后吻合线处出现肺结节的病例应考虑非结核分枝杆菌病的可能性。
