Lipohyperplasia of the ileocecal valve as a cause of intussusception.

We present a case of lipohyperplasia of the ileocecal valve causing episodes of intussusception, and visualized by abdominal ultrasound and CT as a "target-like" appearance. At surgery, a large yellow soft mass was in the region of the ileocecal valve, raising the suspicion of lipohyperplasia. Resection of the fatty tissue from the ileocecal valve was performed at operation, after histologic diagnosis on frozen section. Our case suggests that limited resection removing the terminal ileum is effective and preferable to more extensive resection.
