The case of a 12-year-old girl with fibrous dysplasia involving the cranial vault is presented. The external carotid angiogram demonstrated a dilated and beaded zygomatico-orbital branch of the superficial temporal artery, a faint tumor stain, and an early filling vein. The mass was moderately vascular at the operation and histological examination demonstrated no malignancy.
