Malignant subfrontal (olfactory) @entity1263 (MPNSTs) are exceedingly rare. Although @entity1653 are the most common subfrontal extra-axial lesions, it is important to recognize that MPNSTs, which are radiographically similar to @entity1653 , can also be present in this location. MPNSTs require more aggressive surgical and postoperative management than @entity1653 . In this paper, we describe a @entity1 with a subfrontal @entity808 with unusual histological characteristics and present a review of the literature. A 49-year-old @entity1 presented with chronic @entity1244 and progressive @entity10 . A neurological examination revealed @entity10584 . Brain-imaging studies revealed a large left subfrontal mass with extension into the frontal and ethmoid sinuses and the nasal cavity. The @entity1 underwent both a bifrontal transbasal craniotomy and a transnasal approach for an attempt at total resection of both the intradural and extradural components of the @entity808 . The @entity1 was treated postoperatively with radiation therapy, and had no evidence of recurrence at her follow-up examination 1-year after treatment. Subfrontal PNSTs are extremely rare and usually benign. The specific cell and nerve of origin for these @entity5 remains unknown. Our case shows that these rare lesions can present as a malignant variant and thus require aggressive surgical and postoperative management to provide long-term @entity5 control.
