Extraluminal colonic arteriovenous haemangioma: An unusual cause of chronic lower gastrointestinal bleeding

Abstract

Lower gastrointestinal bleeding is a common general surgical presentation in acute and chronic settings. Vascular anomalies account for 2% of such cases and can therefore be missed. We discuss a rare vascular anomaly in one of our patients where the diagnosis was not established for a ten-year period. We describe the subsequent management and a brief review of the literature of this uncommon condition.
