case_images: A: Pure tone audiometry shows the right deafness on the day symptom developed. B: There is no interval change after 6 months later.

case_images: Pure-tone audiometry was normal in the left ear, while both bone and air conduction threshold in the right ear were unresponsive (Fig. 1A). However, both bone and air conduction threshold in the right ear was not improved (Fig. 1B).
case_images: A: T1-weighted axial view of brain MRI following gadolinium enhancement shows multiple enhancing nodules 4 mm or less in size with a random distribution in the whole brain parenchyma. B: T1-weighted coronal view with gadolinium enhancement shows enhancing nodule in right vestibule (arrow). C: There are no abnormalities in brain CT scan images taken 2 months after the treat-ment. CT: computed tomography.

case_images: T1-weighted axial magnetic resonance imaging revealed multiple nodules 1-4 mm in size with high signal intensity randomly distributed around the cerebral subcortex, pons, and cerebellum (Fig. 2A). T1-weighted coronal images showed high signal distributed by vestibulocochlear area and some parts of semicircular canal area (Fig. 2B). Two months later, the multiple nodules were no longer found in the brain CT (Fig. 2C).
