Subfrontal gangliocytoma masquerading as olfactory groove meningioma

Br J Neurosurg. 2009 Feb;23(1):79-82. doi: 10.1080/02688690802308695.


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.
