Subfrontal Neurilemmoma:A Case Report and Review of the Literature

Abstract

A subfrontal neurilemmoma in a 22-year-old man is reported and the relevant literature is reviewed. Neurilommoma in the subfrontal location is very rare and the precise origin of this tumor still remains uncertain in spite of several suggestions such as the olfactory bulb, the perivascular nerve plexus, the mesodermal pial cell, the meningeal branch of the trigeminal nerve, and the anterior ethmoidal nerve. In our case, the olfactory bulb or tract could be excluded as an origin because the tumor was not attached to those structures and olfactory function was entirely restored after operation. The meningeal branch of the trigeminal nerve is considered as the origin in our case.
