Developmental venous anomaly–associated lesions in patients with MS. A, An axial contrast-enhanced T1 sequence shows a right frontal lobe DVA (arrow) with surrounding T1 hypointensity. B, An axial FLAIR sequence shows hyperintensity (arrow) that corresponds to the DVA and associated T1 hypointensity in A. C, An axial contrast-enhanced T1 sequence shows a right frontal lobe DVA (arrow). D, A sagittal FLAIR sequence shows a flow void with adjacent hyperintensity (the central vein sign, arrow), which corresponds to the DVA in C. E, An axial contrast-enhanced T1 sequence shows a left frontal lobe DVA (arrow). F, An axial T2 sequence shows a flow void with adjacent hyperintensity (the central vein sign, arrow), which corresponds to the DVA in E.
