White matter lesions are seen commonly on MRI brain scans. But they are nonspecific and can be seen with many things including ischemia (limited blood supply) of the small perforating vessels, demyelination such as in multiple sclerosis, old injury, vasculitis, infection such as Lyme disease, or migraine headaches.
In this video we see a typical pattern seen in patients with migraine headaches.
