Multiple Sclerosis (MS) is a relapsing condition caused by the destruction of myelin sheaths.
Ninety percent of MS-related lesions can be detected on T2 MRI images.
These lesions are typically para-ventricular, sometimes ovoid in shape (referred to as "Dawson's Fingers"), and often located on medullary veins.
