Common abnormality on MRI of brain in migraineurs

What is a common abnormality on MRI scans of the brain in migraineurs? 

White matter abnormalities are present on MRI scans more often in migraineurs (variably reported in 12% to 46%) than in controls (2% to 14%).

White matter abnormalities are foci of hyperintensity on both proton density and T2-weighted images in the deep and periventricular white matter due to either interstitial edema or periventricular demyelination of uncertain etiology.
