Mesenteric intestinal lymphangioma is a rare benign lymphatic malformation, typically asymptomatic and often detected incidentally on imaging studies. However, when radiological uncertainty exists, the differential diagnosis should primarily include peritoneal carcinomatosis. We present the case of a 47-year-old woman in whom a mesenteric cystic lesion consistent with this entity was identified. In the absence of symptoms or signs of complication or malignancy, clinical and radiological follow-up was chosen.
