Adult intussusception: An unlikely diagnosis

Intussusception happens when a portion of bowel telescopes into the adjacent bowel segment. It is a rare condition in the adult population, particularly in the young adult, and poses a diagnostic dilemma to the attending clinician because of its variable clinical presentation. Radiological imaging is important in the early diagnosis, and it allows prompt surgical management to avoid severe complications, particularly bowel ischaemia and necrosis. This case report describes the clinical and multimodality radiological findings of an ileocolic intussusception secondary to a mucosa-associated lymphoid tissue (MALT) lymphoma in a young adult patient.
