A 32-year-old woman is referred to a neurologist for evaluation of unsteady gait and numbness in the right foot. Examination reveals weakness of the right lower extremity with muscle spasticity and decreased vibratory sensation. MRI studies show cerebral and spinal cord changes suspicious for demyelinating lesions. A lumbar puncture is performed for examination of CSF. Which of the following CSF findings would be most consistent with a diagnosis of demyelinating disorder?
(A) Elevated protein with marked lymphocytosis
(B) Elevated protein with normal cell count
(C) Marked neutrophilic leukocytosis with reduced glucose
(D) Mildly increased protein with oligoclonal IgG bands
(E) Normal protein with mild lymphocytosis
