[Ann Emerg Med. 2016;68:519.] A 12-year-old boy with a recent history of sinusitis and acute otitis media presented to the emergency department with 3 weeks of upper neck pain and generalized weakness. He also reported headaches and occasional diplopia and vomited twice the day before presentation. The patient was afebrile, with normal vital signs. On examination, he was listless and found to have a left-sided ear effusion, left-sided total facial paralysis, left-sided hearing loss, mild left upper extremity weakness, and ataxia. Laboratory values were significant for an increased WBC count of 30.42 103/mL and a C-reactive protein level of 15.7 mg/L.
