input: The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 31-year-old female patient complains of numbness and tingling in her left hand, weakness, difficulty with walking, dizziness, and bladder dysfunction. She said that about a year ago, she had trouble with her vision, and that it eventually recovered in a few days. On physical exam, bilateral internuclear ophthalmoplegia, hyperreflexia in both patella, and bilateral clonus, are noted. A magnetic resonance imaging (MRI) study was done (Figure 1). If a lumbar puncture is performed in this patient, which of the following would most likely be found in cerebrospinal fluid analysis?   (A) Presence of 14-3-3 protein   (B) Decreased glucose with neutrophilic predominance   (C) Oligoclonal IgG bands on electrophoresis   (D) Decreased IgG CSF concentration
