Vestibular neuritis is characterized by the sudden onset of nausea, vomiting, and spontaneous horizontal or horizonto-rotatory nystagmus. The etiology of the disease is multifactorial. Mumps, rubella, herpes simplex virus type 1, cytomegalovirus, and Epstein-Barr virus may have a role in the disease. Enteroviruses are among the other rare causes. This report presents a 7-year-old male admitted with nausea, vomiting, rotatory vertigo, horizonto-rotatory nystagmus with positive Romberg's sign and positive head-thrust test. Cranial magnetic resonance imaging and audiometry of the patient were normal. He was diagnosed with vestibular neuritis, and steroid therapy was initiated. At the second month of follow-up, all symptoms had regressed. To the best of our knowledge, this case report describes the first pediatric patient in whom enteroviral ribonucleic acid is documented both in cerebrospinal fluid and in nasopharyngeal material in active disease. This finding supports the possible role of enteroviruses in the etiology of vestibular neuritis.
