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).

Non-tuberculous Mycobacteria (NTM) are found extensively in various environments, yet most are non-pathogenic. Only a limited number of these organisms can cause various infections, including those affecting the lungs, skin, and central nervous system, particularly when the host's autoimmune function is compromised. Among these, Non-tuberculous Mycobacteria Pulmonary Diseases (NTM-PD) are the most prevalent.

Background: Idiopathic CD4+ T lymphocytopenia is a rare immune dysfunction disease that is usually found after opportunistic infections. Mycobacterium abscessus is a rapidly growing mycobacterium that can cause pulmonary infections, lymphadenitis, skin and soft tissue infections, disseminated infections, among others, as a conditional pathogenic bacterium.
Case Presentation: We present the case of a 43-year-old Chinese woman who developed disseminated Mycobacterium abscessus infection due to idiopathic CD4+ T lymphocytopenia.
