Subfrontal Schwannoma: Case Report and Review of Literature.

BACKGROUND

Although attributing the origin of schwannomas from the olfactory nerve is nearly impossible, if they do not have Schwann cells, intracranial supratentorial schwannomas are mainly located in the anterior skull base.

CASE DESCRIPTION: We present the case of a 46-year-old female who presented with right tinnitus, dizziness, and bifrontal headache, progressive, starting 2 years before. Imaging studies revealed an incidentally neoplastic, extraaxial, homogeneously appearing tumor on the right anterior skull base. The patient underwent surgical treatment with total resection of the tumor by a bicoronal approach. The histopathologic study reported schwannoma.

CONCLUSION

We describe this case in detail and discuss the likely origin of this tumor, with a concomitant literature review.
