Small bowel obstruction due to mesenteric abscess caused by Mycobacterium avium complex in an HIV patient: a case report and literature review

Abstract

Small bowel obstruction in HIV patients is reportedly caused by inflammatory pseudotumor, Kaposi's sarcoma, cryptococcal lymphadenopathy and intestinal tuberculosis. The incidence of Mycobacterium avium complex (MAC) infection in HIV patients is 3% for CD4 cell count of 100–199 /mm³. MAC causing small bowel obstruction is rarely reported in the literature. We report a rare case of MAC causing mesenteric abscess with small bowel obstruction in a HIV patient with a CD4 cell count of 144 /mm³. Patient was a 35-year-old HIV-positive male on highly active antiretroviral therapy who presented with partial small bowel obstruction secondary to mesenteric abscess. He underwent operative intervention for drainage with cultures growing MAC.
