Cavernous haemangioma of the rectum: an uncommon cause of rectal bleeding.

Cavernous haemangioma of the rectum is an uncommon cause of rectal bleeding. Initial diagnosis is often elusive because of lack of awareness. For accurate diagnosis, investigations such as endoscopy, plain X-ray of the abdomen, barium enema and selective angiography of the inferior mesenteric artery are required. Complete surgical excision of the haemangioma and colo-anal sleeve anastomosis is the most favoured operative procedure to eradicate the disease. We report a case of cavernous haemangioma of the rectum and discuss its salient clinical features, investigations and management.
