Ms. Snow came in complaining of weakness in her legs and a tingling sensation in parts of her left arm. She had a series of blood tests done, as well as an MRI. The MRI showed a few lesions on her spinal column and brain, what might this suggest?
  1. Muscular dystrophy
  2. Multiple sclerosis
  3. Myasthenia gravis
  4. None of the above
Explanation
Answer - B - Multiple sclerosis affects multiple body systems and can have a huge neuromuscular effect as autoantibodies break down the myelin sheath that protects the brain and spinal column. One of the diagnostic hallmarks of the condition is lesions seen on the MRI where this breakdown has occurred. Additional testing by a neurologist would always be recommended to make final diagnosis and treatment.
