Mesenteric infantile hemangioma: diagnostic work-up

A very rare localization of infantile hemangioma (IH) is mesentery. It may manifest with intra-luminal or intra-peritoneal bleeding. Here there is the case of a 45-day-old infant, presenting with anemia and poor growth, subsequently referred to an uncommon hemangioma of the mesentery. As well as for most of IH, conservative treatment with only propranolol resulted in the disappearance of the lesion. Here we analyze ultrasound and magnetic resonance (MR) features of this uncommon lesion, trying to underline main characteristics at imaging in order to monitor the response to therapy.
