Extensive Hemangiolymphangioma of the Small Bowel Mesentery: A Case Report.

Hemangiolymphangioma is a rare malformation of the vascular and lymphatic system affecting different parts of the human body. Hemangiolymphangioma of the small bowel mesentery is extremely rare. We report the case of a 23-year-old woman who presented with generalized colicky abdominal pain. Computed tomography findings were initially thought to represent possible secondary mesenteric and peritoneal metastatic deposits. However, no primary tumor was identified. A pelvic magnetic resonance imaging was then performed, which favored the diagnosis of extensive mesenteric lymphangiomatosis. The diagnosis was confirmed histopathologically as hemangiolymphangioma of the small bowel mesentery.
