Abstract:
Bilateral internal auditory canal (IAC) tumors are usually pathognomonic for vestibular schwannomas in the setting of neurofibromatosis type 2 (NF2). Descriptions of bilateral nonschwannomatous IAC tumors, such as metastasis that may mimic NF2, are limited to case reports. Here, we report a case of unusual metastatic bilateral IAC tumor originating from the ovary with a rapidly progressive pattern, which we initially suspected to be NF2.
