A Case of Giant Mesenteric Hemangioma with involvement of the mucosa of duodenum and pancreatic parenchyme / 대한내과학회지

ABSTRACT

A giant mesenteric hemangioma with small intestinal involvement was rarely found as the cause of recurrent gastrointestinal bleeding. Enteric hemangiomas account for 7~10% of all benign tumors of the small intestine and the jejunum is the most common location. A 52-year-old man was admitted with recurrent melena for 4 years. Submucosal tumor like elevated lesion was found at just distal Ampulla of Vater. This lesion was seen woozing type bleeding. For evaluation of bleeding focus, mesenteric angiogram was done. A mesenteric angiogram revealed normal gastro-duodenal, superior and inferior mesenteric arteries. Whole abdominal computed tomography revealed low- density lesion at distal to duodenal 2nd portion. To prevent further recurrent bleeding, Whipple's operation was done. The histologic diagnosis of the lesion was a giant mesenteric hemangioma of mesentery with involvement of the mucosa of duodenum and pancreatic parenchyme.
