Olfactory Groove Meningioma Syndrome

Olfactory groove meningiomas can present as the FosterKennedy syndrome with optic atrophy and central scotoma in the ipsilateral eye papilledema in the contralateral eye and ipsilateral anosmia due to optic and olfactory nerve compression and increased intracranial pressure.

Altschul Leads SVIN Discussion on New Stroke Treatments Dr. The more the OGM shows starting point or growth development to or from the anterior chiasmal angle the more is resembles that psychopathological syndrome that we have found and described for the meningioma of the Tuberculus sellae.

A histopathologic study of the excised specimen disclosed a meningioma. Olfactory groove meningiomas arise over the cribri-form plate and frontosphenoid suture and comprise ap-proximately 10 of intracranial meningiomas515 Al-though these tumors arise in the midline they may extend predominantly to one side.
