[A Case of Pulmonary Nontuberculous Mycobacterial Infection Accompanied with Intraductal Papillary Mucinous Neoplasm].

An 87-year-old woman presented to the emergency department with left thigh pain, and sciatic nerve pain was diagnosed. A chest CT scan showed bronchiectasis and tree-in buds and an acid-fast stain test of gastric juice was positive; further, M. avium-PCR of sputum and culture results were positive leading to a diagnosis of pulmonary nontuberculous mycobacterial infection(NTM). Abdominal CT showed dilatation of the main pancreatic duct and a multifocal cystic tumor in the pancreatic tail, which was found to be complicated with an intraductal papillary mucinous tumor(IPMN).
