An audiogram revealed SNHL with pure tone threshold of 43.7 dB in the left ear (Fig. 1).
Contrast-enhanced axial-T1 weighted images of MRI demonstrated that faint enhancement of basal turn of cochlea, vestibule, semicircular canals and intense enhancement of mastoid in the left side. These MRI findings are suggestive of otitis media with mastoiditis and tympanogenic labyrinthitis.
