The ileocecal valve is the divider between the small bowel and cecum. It is seen by pathologist in some subtotal colectomies (e.g. right hemicoloectomies) and occasionally biopsied.
Lipomatous ileocecal valve
- AKA Lipomatosis of the ileocecal valve
General
- The lesion should involve the valve circumferentially.
- True lipomas of the ileocecal have a capsule, are not circumferential and less common.[1]
Clinical:
- May be misdiagnosed as malignancy.[2]
- Reported to mimic Crohn's disease.[3]
