Magnetic resonance imaging and High resolution computed tomography with contrast temporal bone showed extensive bony destruction and petrous apex lesion. Facial nerve and vestibular cochlear nerve was compressed by abnormal soft-tissue present in the internal auditory meatus. Transmastoid translabyrinthine exploration was carried out for petrous apex lesion. Intra-operative extensive bony erosion was noted in the temporal bone.
