Severe colonic diverticulitis in an adolescent with Williams syndrome

Williams Syndrome (WS) is a condition with multisystemic involvement caused by a genetic deletion in chromosome 7. Colonic diverticulosis has been described in adults with WS; however, it has not previously been reported in adolescents with WS. We report an adolescent boy with WS who developed complicated colonic diverticulitis and briefly review the possible aetiology of diverticular disease.
