Endobronchial Mycobacterium Avium-Intracellulare Infection in Lung Transplant Recipients.

Endobronchial Mycobacterium avium-intracellulare (MAI) infection has been described in immunocompromised patients but is rare among transplant recipients. We present a case of a 48-year-old male with a history of coal miners' pneumoconiosis who underwent bilateral lung transplantation. Ten months post-transplant, despite normal spirometry and absence of respiratory symptoms, routine surveillance bronchoscopy revealed multiple endobronchial polypoid lesions.
