Cavernous haemangioma of the duodenum. A rare cause of gastrointestinal bleeding.

Vascular malformations (VMs), including haemangioma, of the upper gastrointestinal tract, are rare causes of bleeding. Bleeding from these lesions is often recurrent and diagnosis is often delayed for months to years. A patient with severe, recurrent upper gastrointestinal bleeding requiring repeated hospitalization and blood transfusions is presented. Upper endoscopy, barium meal and small bowel enteroclysis were negative. Selective mesenteric angiography revealed a VM in the second part of the duodenum. Segmental resection of the duodenum was performed and microscopical examination showed cavernous haemangioma. VM should be considered in patients with recurrent gastrointestinal bleeding and negative conventional investigations. Mesenteric angiography may be the only investigation which will identify these lesions. Results after excision are excellent.
