Multiple sclerosis attack case presenting with pseudo-vestibular neuritis

Pseudo-vestibular neuritis is a clinical diagnosis for patients presenting with acute vestibular syndrome due to a central pathology.

We reported a case of multiple sclerosis characterized by pseudo-vestibular neuritis. Our case was a 32-year-old male patient. The patient, who was diagnosed with multiple sclerosis in September 2019, came to the emergency clinic in January 2020 with the complaint of severe vertigo, vomiting-nausea. A newly developed demyelinating plaque was detected in the left vestibular nucleus in cranial MRI. The patient had no hearing loss. On examination of the patient, nystagmus findings supporting peripheral vestibular involvement were present on the left side. Neurologic examination showed left-sided hyperactive deep tendon reflexes, Achilles clonus, dysmetria, ataxia to the left and plantar reflex with extensor response on the left. Video head impulse test and cervical evoked myogenic potential tests were performed. Vestibular hypofunction was present on the left side. Steroid pulse therapy was administered as 1000 mg/day, i.v for 7 days. After treatment, his complaints decreased. In addition, there was an improvement in examination findings.

Multiple sclerosis is shown to be an etiological factor in patients with pseudo-vestibular neuritis.
