Cavernous colorectal hemangioma - A rare cause of lower gastrointestinal bleeding and a review of the literature

Colorectal hemangiomas are rare causes of gastrointestinal bleeding. Most patients present in young adulthood with frequent, recurrent, and occasionally profound bleeding. The reported mortality rate is as high as 40- 50%. Although the need for recognition is accepted, the diagnosis is often missed due to the infrequency of occurrence. It is, therefore, important that hemangiomas be considered in the appropriate clinical circumstances to ensure effective intervention. This report describes the clinical, endoscopic, and radiologic features of a rare case of a cavernous colorectal hemangioma.
