Mesenteric Venous Malformation With Subocclusive Symptoms: A Case Report.

Venous malformations, previously referred to as cavernous hemangiomas, can affect the gastrointestinal tract and rarely the mesentery. When symptomatic, it can cause pain, hematochezia, or less frequently obstructive symptoms. In this paper, we report the case of a 60-year-old man who presented to the emergency department for abdominal pain and subocclusive symptoms. A CT scan with intravenous contrast revealed a well-defined mesenteric mass measuring 3.5 × 3.2 cm in the pelvic region with a localized anterior panniculitis. A surgical resection was performed which led to resolution of obstructive symptoms, with the histopathological analysis confirming the diagnosis of mesenteric venous malformation.
