title: Abdominal tuberculosis presenting as ileocolic intussusception in an infant.
abstract: Intussusception is the most common cause of intestinal obstruction in children, with a peak in children 5 to 7 months of age. Identifiable causes are found in 90% of adults, whereas in infants and young children the majority are idiopathic. We report a case of abdominal tuberculosis (ATB) presenting as an ileocolic intussusception in an infant. A 6-month-old infant presented with features of acute intestinal obstruction. Peroperatively, ileocolic intussusception was found. Histological examination revealed caseating epitheloid cell granulomas with positivity for acid-fast bacilli. Only 3 cases of ATB presenting as intussusception have been previously reported in the literature, with only 1 case presenting in a child. This appears to be the 2nd case of ATB presenting as an intussusception in a child and also in an infant. Tuberculosis should also be kept in the differential diagnosis of lead point of intussusception, even in the age group in which most cases are idiopathic, especially in endemic areas.
