Abstract
|
|
|
|
Meningiomas arising outside the intracranial compartment are known as extradural meningiomas. Extradural meningiomas are rare conditions, accounting for less than 2% of all meningiomas. Primary intraosseous meningioma is used to describe a subset of extradural meningiomas arising from bone. A 46-year-old woman presented with left exophthalmos. Computed tomography and magnetic resonance images revealed an expansile bony lesion in the orbital lateral wall of the left sphenoid bone. The patient underwent craniotomy for excision of the bony lesion. Pathologic examination revealed an intraosseous meningioma.
