Mycobacterium avium-avium-associated typhlitis mimicking appendicitis in an immunocompetent host

Am J Med Sci. 2009 Mar;337(3):218-20. doi: 10.1097/MAJ.0b013e31818457a3.


Mycobacterium avium-intracellulare complex (MAC) primarily causes respiratory infection in patients with underlying lung disease or disseminated disease in immunocompromised patients. We report a unique case of MAC disease in the terminal ileum of a healthy patient, mimicking appendicitis. This case emphasizes the need to further explore MAC pathogenesis in immunocompetent hosts.
