Unilateral Proptosis in Young Man: A Rare Manifestation of Intraosseous Meningioma

Benign primary intraosseous meningioma presented as unilateral proptosis is a rare case in our settings. The reported occurrence is 1%-2% of all meningiomas. This type of tumour has numerous nomenclature that represents its location outside the dural component, such as ectopic, extracranial, calvarial and extraneuraxial. Although it is a benign entity, the tumour can cause significant disfigurement, especially in the context of young individuals. We report a rare case of intraosseous meningioma of frontal and greater wing of sphenoid bone presented as proptosis in a young patient.
