Figure 1. Initial hearing threshold with a weighted four-frequency average ([500 Hz +1000 Hz × 2 + 2000 Hz × 2 + 4000 Hz]/6) on pure tone audiometry was 32 dB in the right ear and indicated deafness in the left ear.

Figure 2. On temporal magnetic resonance imaging, an abnormal hyperintense lesion was observed at the left cochlea and vestibule on T1-weighted imaging (arrow) (a), which was not enhanced on T1-weighted imaging with contrast (arrowhead) (b).
