A case of intussusception and lymphoid hyperplasia in a patient with AIDS.

Idiopathic intussusception in adults is rare. In tropical climates, enteric infection is causally implicated. Three cases of intussusception in AIDS patients have been reported, two of which were associated with enteric infection. We report the fourth case of ileocolonic intussusception in an AIDS patient in whom lymphoid hyperplasia of the terminal ileum was found but no infection documented. The relationship between lymphoid hyperplasia and intussusception is discussed. The previous cases of AIDS and intussusception are reviewed. Idiopathic intussusception may become more prevalent as the number of AIDS cases increases, and must be considered in the differential diagnosis of abdominal pain in AIDS patients.
