title: Subfrontal gangliocytoma masquerading as olfactory groove meningioma.
abstract: We describe a rare case of an unusually located gangliocytoma. The conventional magnetic resonance imaging (MRI) appearance was suggestive of an olfactory groove meningioma. However, advanced MRI sequences (diffusion-weighted imaging--DWI; perfusion MRI; susceptibility-weighted imaging--SWI; MR spectroscopy--MRS) revealed features more consistent with a glial neoplasm.
