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.
本研究的目的是确定骨内脑膜瘤（IOMs）的各种影像学特征，并区分低级别和高级别肿瘤。组织病理学评估显示，56例（86%）患者为世界卫生组织（WHO）I级肿瘤，8例（12%）为II级，1例（2%）为III级。WHO I级被认为是低级别，II级和III级被指定为高级别。骨肥厚最常见于低级别IOMs。伴有放射状骨针的混合性骨肥厚/溶骨模式以及头皮肿块的存在似乎更常与高级别IOMs相关。
