Sudden sensorineural hearing loss as presenting symptom of multiple sclerosis in a 15-year-old girl

Audiometry showed moderate flat sensorineural hearing loss on the right and severe left sensorineural hearing loss.

(A) Axial T2-W FSE image through the posterior fossa demonstrates multiple lesions in the white matter of the pons, in the middle cerebellar peduncles and cerebellar hemispheres. One lesion is located in the pons, at the root entry zone of the right acoustic nerve; (B) MR sagittal T2-W FLAIR image showed multiple high-intensity ovoid lesions in the white matter of the supratentorial compartment, typically located along the periventricular regions, distributed in a perivenular manner in the centrum semiovale and in the corpus callosum.
