Colonic Varices and Portal Hypertension Presenting as Unexplained Anemia: A Case Report

Colonic varices are rare venous dilatations associated with portal hypertension, often due to hepatic cirrhosis or portal vein obstruction. They can cause lower gastrointestinal bleeding and anemia, with diagnosis primarily made through colonoscopy.

This case report presents a 55-year-old male with unexplained anemia, where colonoscopy revealed colonic varices. Imaging showed portal vein thrombosis, leading to the diagnosis of portal hypertension. The patient was treated with anticoagulants and beta-blockers, showing clinical improvement after six months.

Although colonic varices are rare, this uncommon case emphasizes the need to consider rare diagnoses in patients with unexplained anemia and gastrointestinal bleeding. It also highlights the importance of considering colonic varices in patients with unexplained anemia, particularly when portal vein thrombosis is present.
