Case 1 Presentation
A 4-year-old boy has had 6 days of intermittent nausea and vomiting without diarrhea or fever. Two days into the illness, he was given promethazine suppositories for presumed viral gastroenteritis; overnight the vomiting subsided. He now experiences an unsteady gait and needs help to stand still for urination. He says that he sees “two daddies.” There has been no weight loss, headache, mental status changes, upper respiratory tract symptoms, skin lesions, or trauma.

An imaging study reveals the cause of his vomiting, ataxia, and diplopia.
