Background: The presence of periventricular lesions (PVL) on MRI scans is part of the revised McDonald
multiple sclerosis (MS) diagnostic criteria. However, PVL can be found in other neurological diseases including stroke
and migraine. Migraine is highly prevalent in patients with MS.
Objective: To determine if PVL are specific for patients with MS compared to stroke and migraine.
Methods: We studied patients diagnosed with clinically isolated syndrome (CIS), relapsing-remitting MS (RRMS),
migraine, and ischemic stroke. The number, location and the volume of PVL were identified on brain MRI scans and
analyzed.
Results: The number and volume of PVL adjacent to the body and the posterior horn of the lateral ventricles
were significantly increased on fluid-attenuated inversion recovery MRI in RRMS compared to migraine. There were.. View More»
