Intralabyrinthine schwannoma involving the cochlea, vestibule, and internal auditory canal: 'canalolabyrinthine schwannoma'.
Intralabyrinthine schwannomas (ILSs) are very rare and most of them involve cochlea-vestibule, internal auditory canal (IAC)-cochlea, or IAC-vestibule areas. However, there is no study reporting on schwannomas involving simultaneously the vestibule, cochlea, and IAC. We report a case of schwannoma involving simultaneously the vestibule, cochlea, and IAC, with the discussion of its possible origin and propose one more new classification, the 'canalolabyrinthine schwannoma', among the ILSs.
