title: HMPAO scintigraphy, MRI, and CT of a vascular fibrous dysplasia of the craniofacial bones.
abstract: The authors present the case of a child with a predominantly unilateral craniofacial fibrous dysplasia and a substantial redirection of internal carotid blood flow to the dysplastic bone. The case illustrates the advantages of using multiple imaging modalities in the evaluation of this disorder. CT showed the diagnostic findings of fibrous dysplasia and demonstrated the extent of bony involvement. MRI showed the extent and vascularity of the intradiploic fibrous mass and best demonstrated the distortion of underlying cerebral structures. Tc-99m HM-PAO brain scintigraphy demonstrated adequate ipsilateral cerebral perfusion, thereby excluding any significant cerebral "steal."
