Intussusception in an adult always raises concerns for underlying malignancy. Intra-lumenal masses or tumors can act as a lead point wherein, via peristalsis, the more proximal bowel can "grab hold" and intussuscept.
Fortunately, this patient had a benign submucosal fibroid tumor that led to her intussusception. We resented the segment of bowel harboring the mass and she went home a happy camper in a couple of days. Many times, intussusception is the initial presentation of a more sinister process, like lymphoma, or carcinoid tumors, or invasive adenocarcinomas.
