The enigmatic origin of subfrontal schwannomas: report of a case without hyposmia

Acta Neurochir (Wien). 2006 Jun;148(6):671-2; discussion 672. doi: 10.1007/s00701-005-0720-2. Epub 2006 Feb 9.

Abstract

Subfrontal schwannomas are rare intracranial tumors. Most of them are associated with hyposmia/anosmia. The source of origin of these tumors is still incompletely understood. We report a 23-year-old male who presented with recurrent focal motor seizures, but had no hyposmia. The tumor was completely removed by a subfrontal approach. Relevant literature has been reviewed.
