title: Primary Intraosseous Meningioma.
abstract: Primary intraosseous meningiomas are a subtype of primary extradural meningiomas. They represent approximately two-thirds of extradural meningiomas and fewer than 2% of meningiomas overall. These tumors originate within the bones of the skull and can have a clinical presentation and radiographic differential diagnosis different from those for intradural meningiomas. Primary intraosseous meningiomas are classified based on location and histopathologic characteristics. Treatment is primarily surgical resection with wide margins if possible. Sparse literature exists regarding the use of adjuvant therapies. The literature regarding primary intraosseous meningiomas consists primarily of clinical case reports and case series. This literature is reviewed and summarized in this article.
