The Variable Bone Scan Appearances of Nonosteogenic Fibroma of Bone

Abstract

Ten radiographically diagnosed fibrous defects of bone were assessed by three-phase bone scanning. Normal scans are obtained when the lesion is quiescent of has fully heated. Mild hyperemia and moderate bone uptake is present during the healing phase and is not significant. More intense hyperemia and a markedly positive bone scan suggest that a more active process, such as fracture or tumor, may be present.
