A 9-year-old male, with no significant past medical history, presents to the office with dizziness over 3 days. He reports sudden onset of a “queasy” feeling at bedtime. He then awoke from sleep with a “spinning” sensation, vomited, and felt off balance. Family reports that he looked pale during the episode and was unable to open his eyes due to the spinning sensation. Family was unable to evaluate for nystagmus. He vomited several times and then fell asleep. The next day he stayed in bed all day and continued to complain of a constant spinning sensation. By the following day, patient was off balance, but returned to school.

Patient denied tinnitus, hearing loss, headaches, blurred vision, nystagmus, loss of consciousness, frequent falls, weakness of the arms or legs, chest pain, light sensitivity, or noise sensitivity.
