A 56-year-old woman was found to have a solitary mass shadow on chest radiograph in a health examination.Transbronchial examination on two occasions did not yield any diagnostic findings.Both the highlevel of CA19-9 and the increasingly large shadow were suspected to be indicative of lung cancer, so we performed left lower lobectomy.The pathological examination of the resected lung revealed a granulomatouslesion without malignant findings.A few colonies grew on a liquid medium,and were identified as Mycobacterium avium by PCR.After operation,the increased CA19-9 leval normalized gradually.There are few reportspresenting a solitary pulmonary mass shadow and high CA19-9 level due to nontuberculous mycobacterial disease.
