A twenty-two-year-old Olympic-caliber collegiate swimmer presented to the emergency department with complaints of progressive weakness in both lower extremities. Two days earlier, the patient had noted sharp pain in the neck and the middle part of the back on waking; however, he was able to complete his morning swimming practice. He could not recall a traumatic event, but he had participated in a rigorous swim practice the day before. One day before presentation, the pain completely resolved. However, on the day of presentation, the patient had awoken from a nap with searing interscapular back pain and decreased strength in the legs. He reported no bladder or bowel difficulties at that time. He was unable to stand and was immediately taken to the emergency department.
