Solitary olfactory groove schwannoma.
Intracranial schwannomas that do not involve major cranial nerves in the posterior fossa are uncommon, especially if they are not associated with neurofibromatosis type II (NF-2). Subfrontal olfactory groove schwannomas are extremely rare. We report a cystic schwannoma arising from the olfactory groove in a 38-year-old Caucasian male who presented with headache, vomiting and visual impairment. We briefly review the pertinent literature, stress the distinctive clinical and neuroradiological findings and discuss the surgical planning and theories about the pathogenesis of schwannomas in this unusual location.
