Embolization therapy in large infantile hemangioma with extensive perfusion. In MRI, the hemangioma presents as a rather homogeneous, solid mass with central flow voids (a). Dynamic MR-A shows massive AV shunting during the early venous contrast phase (b). Transarterial particle embolization was performed to reduce the flow and induce a regression with a protection balloon in the draining vein (c)
