Abstract

The aim of this study was to determine various imaging features of intraosseous meningiomas (IOMs) and differentiate low grade from high-grade tumors. The histopathologic evaluation revealed WHO grade I tumor in 56 (86 %) patients, grade II in 8 (12%) and grade III in 1 (2 %) patient. WHO grade I was considered low grade and II and III were designated as high grade. Hyperostosis was observed most commonly in low-grade IOMs. Mixed hyperostotic/lytic pattern with radial bony spiculations, and presence of a scalp mass seem to be more frequently associated with higher grade IOMs.
