Summary: Hemangioendotheliomas are rare vascular tumors that can affect bone. They account for 0.5% to 1.0% of malignant primary bone tumors. Only four cases have been reported involving the temporal bone. A 5-year-old child with grade II hemangioendothelioma of the right temporal bone is presented, and the radiologic findings on different imaging studies are described. The patient was treated with preoperative endovascular embolization followed by wide surgical resection. The imaging patterns of this malignant tumor may be similar to those of a benign lesion.
