Small filling defect within the basal turn of the left cochlea with corresponding focus of enhancement. Small enhancing focus within the left amygdala probably represents incidental capillary telangiectasia.

Tiny filling defect and focus of enhancement within the left basal turn of cochlear most in keeping with intracochlear schwannoma (labyrinthine schwannoma). Audiometry confirmed localized dip in high frequency hearing on the left corresponding to the site of the lesion.
