Review Question - QID 206113

A 26-year-old Caucasian female presents to her primary care physician because she is concerned about recent changes to her health. She states that for the past year she has had recurrent episodes of vision problems. She states that seemingly "out of the blue" her vision will become very poor and she will have pain whenever she moves her eyes. These episodes tend to last for a short time and then spontaneously resolve on their own. Upon questioning, the physician learns that she has also had periodic episodes of balance and speech difficulties which seem to self resolve in a similar fashion to her eye complaints. The physician orders an MRI which is demonstrated in Figure A. What is the appropriate treatment the next time this patient experiences an acute episode of these neurologic symptoms?
