Multiple jejunal perforation secondary to intestinal tuberculosis infection: a case report.

Abdominal tuberculosis (TB) may affect any part of the gastrointestinal tract resulting in significant morbidity and mortality. There is an increase in the incidence of abdominal TB favored by the emergence of multi-drug resistant Mycobacterium tuberculosis and immunosuppression especially from HIV co-infection. Our case is that of a 31 year old HIV-positive woman, adherent to antiretroviral therapy, who presented with a 2 month history of progressive abdominal distention, drenching night sweat and fatigue, but without fever. She was admitted on a presumptive diagnosis of peritoneal TB, and suddenly developed signs and symptoms of an acute abdomen. Laboratory investigations showed a CD4+ count of 155 cells/µL, white blood cell count of 15,700 cells/mm3 and haemoglobin of 8.0g/dl. An emergency laparotomy revealed small bowel caseous necrosis with multiple jejunal perforations. Ziehl-Nelsen staining of operative specimen was positive for acid fast bacilli. Given her immunodeficiency status, clinical signs and symptoms, CD4 cell count > 50 cells/µL, and intestinal sample showing caseous necrosis and perforations, a final diagnosis of intestinal TB was made. In conclusion, abdominal tuberculosis may mimic a number of intra-abdominal pathologies; thus should always be considered as a differential diagnosis in patients presenting with acute abdomen in TB-endemic areas especially in an HIV-positive individual.
