case_images: Initial lumbar puncture revealed a CSF opening pressure of 140 mmH2O, a WBC count of 120/microl (93% lymphocytes), a protein level of 48 mg/dl, and a normal glucose level ( Figure 2 ). The patient was then treated with intravenous methylprednisolone (500 mg/day for 5 days, followed by a tapering scheme) combined with plasma exchange (5 cycles, every other day) and intravenous immunoglobulin (0.4 g/kg per day for 5 days) ( Figure 2 ).
