Abstract
A 27-year-old woman who was referred to our hospital 5 days after an episode of vertigo had experienced right facial palsy 2 days earlier and a feeling of numbness in her left hand one year earlier. Ocular movement showed rotatory nystagmus in the positioning nystagmus, and the abduction of the right eye was impaired. A T2-weighted magnetic resonance imaging (MRI) study showed multiple high-intensity lesions in the dorsal pons and white matter close to the lateral ventricles, supporting a diagnosis of multiple sclerosis. Methylprednisolone pulse therapy effectively alleviated the patient's complaints except for the feeling of numbness in the left hand, and the patient's ocular movements normalized within one month. A neuro-otology examination, such as the observation of eye movements, is a key study for suspected brain lesion symptoms.
