After operation,the increased CA19-9 leval normalized gradually.There are few reports presenting a solitary pulmonary mass shadow and high CA19-9 level due to nontuberculous mycobacterial disease., Article, 信州医学雑誌 56(6): 365-370(2008)}, pages = {365--370}, title = {孤立性肺腫瘤陰影を呈しCA19-9が高値を示した非結核性抗酸菌症の1例}, volume = {56}, year = {2008} }
