Cutaneous IHs were present in eight patients (five segmental (45%), three multifocal (27%)) and absent in 1 (9%). Segmental hemangiomas involved the face in 2\/5 (40%) and lower body in 3\/5 (60%). The most common symptoms were dyspnea (n\u00a0=\u00a04), hematochezia (n\u00a0=\u00a03), and\/or ulceration (n\u00a0=\u00a02). Three patients were asymptomatic. Involved retroperitoneal organs included the duodenum (n\u00a0=\u00a04), pancreas (n\u00a0=\u00a03), and adrenal glands (n\u00a0=\u00a01). Non\u2010retroperitoneal organ involvement included the liver (n\u00a0=\u00a05), non\u2010duodenal small intestine (n\u00a0=\u00a04), and large intestine (n\u00a0=\u00a03). Perivascular retroperitoneal hemangiomas were seen in 6\/11 patients (55%), most commonly surrounding the aorta (n\u00a0=\u00a05), iliac vessels (n\u00a0=\u00a02), and\/or inferior vena cava (n\u00a0=\u00a02). Three of 11 patients (27%) had LUMBAR based on a segmental, sacral hemangioma with tethered cord or anorectal malformation. Follow\u2010up information was available in 6\/11 patients (55%): 5 symptomatically improved with treatment (propranolol, corticosteroids, and\/or vincristine), while one succumbed from extensive hepatic involvement.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Retroperitoneal IHs are rare and tend to involve organs or surround vessels.
