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 World Health Organization (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.
