Diffuse neonatal hemangiomatosis is a fatal disorder characterired by multiple cutaneous and visceral hemangiomas. The organs most commonly affected are the gastrointestinal tract, brain, liver and lung. The complications are high output cardiac failure, gastrointestinal bleeding and hydrocephalus. We present a patient with diHuse neonatal hemangiomatosis associated with massive hepatic involvement and high output cardiac failure, which was successfully treated with high dose corticosteroid.
