Editor's Note:
The Case Challenge series includes difficult-to-diagnose conditions, some of which are not frequently encountered by most clinicians but are nonetheless important to recognize accurately. Test your diagnostic and treatment skills using the following patient scenario and corresponding questions. If you have a case that you would like to suggest for a future Case Challenge, please contact us.


A 16-year-old boy presents to the emergency department with a 1-week history of weakness in both lower extremities, which progressed to involve both arms over the course of 1 day. He also complains of dysesthesia. No sphincteric dysfunction is noted.

Two weeks before presentation, he had been treated for an upper respiratory tract infection. He has no history of diarrhea, vomiting, or abdominal pain. He is a nonsmoker and is not taking any medications on regular basis. His family history is unremarkable.
