Mandy Wallsmith is a 19-year-old young lady who has been brought to the Emergency Department because of problems walking. Approximately one week ago, she noticed some numbness in her left leg. She thought she had slept on it the wrong way initially, but then the numbness persisted. The next day she fell while skating and landed on her backside. Over the next few days, she reports feeling significant pain in her lower back and progressive “heaviness” in her left leg. She began having difficulty lifting her left leg. She also noticed that her right leg seemed to feel cold when she showered. After speaking to her parents about her symptoms, she was brought to a walk-in clinic where an x-ray of the spine was ordered. This reported no fractures, and Mandy was advised to follow-up with her family doctor if her symptoms did not improve in the next few days. When she started to have episodes of urinary incontinence, her parents became very concerned, and decided to bring her to the Emergency Department.
