Intussusception associated with pneumatosis cystoides intestinalis in a male adolescent: A case report.

Pneumatosis cystoides intestinalis is an uncommon disease that rarely causes intussusception. We report the case of a 16-year-old male patient with intermittent abdominal pain who was diagnosed with intussusception. The patient had no history of raw food ingestion, fever, diarrhea, or hematochezia. Computed tomography revealed intussusception characterized by a crab-finger appearance, and pneumatosis cystoides intestinalis was diagnosed by colonoscopy. Treatment with hyperbaric enema and low-flow oxygen therapy resulted in a prominent improvement of the lesion. No recurrence was observed for > 1 year. Intermittent abdominal pain without diarrhea or hematochezia in male adolescents may represent pneumatosis cystoid-related intussusception, and the addition of low-flow oxygen therapy may help avoid surgery.
