Unilateral vestibular schwannoma associated with a Jacobson's schwannoma

Eur Rev Med Pharmacol Sci. 2014;18(9):1422-5.


Coexistence of unilateral vestibular schwannoma and Jacobson's schwannoma growing in the same intracranial site is rarely observed. We present the case of 36-year-old woman with primary diagnosis of vestibular schwannoma and subsequent appearance of schwannoma to the Jacobson's nerve. Initial wait and see strategy was performed offered us the opportunity to describe Jacobson's lesion features at computed tomography over a period of 4 years. Subtotal petrosectomy with infralabyrinthine approach was subsequently executed to remove the growing mass of the temporal bone. The Jacobson's schwannoma increased its size from 0.4 cm for years whereas vestibular schwannoma size was unchanged after 7 years observation. The concomitant removal of both schwannomas is still associated with the size of the CPA lesion and to patient's symptoms.
