Ectopic Cecal Varices as a Cause of Lower Gastrointestinal Bleeding.

Ectopic varices account for 1%-5% of all variceal bleeding episodes in patients with portal hypertension. They can be found at any part of gastrointestinal tract including the small intestines, colon, or rectum. We report a case of a 59-year-old man who presented with bleeding per rectum 2 days after a routine colonoscopy, in which 2 lesions were biopsied. Gastroscopy was negative for bleeding, and he was not stable enough to undergo colonoscopy. CT angiography showed a large portosystemic shunt with multiple collaterals in the right lower quadrant. These findings were clues for a diagnosis of ectopic cecal varices.
