Given that the treatments and outcomes for MS and its mimics are so different, neurologists should take care to establish a diagnosis early, said Sid Pawate, MD, Assistant Professor of Neurology at Vanderbilt University School of Medicine in Nashville. Because of the varied clinical presentation of MS, a wide variety of conditions enter the differential diagnosis. Because of the central role that MRI plays in MS diagnosis, imaging mimics that cause white matter lesions also need to be considered, said Dr. Typically, the white matter lesions seen in MS are periventricular, juxtacortical, and callososeptal in location.
