“Dawson’s Fingers” on MRI Brain in Small Vessel Ischemia


Dawson’s fingers refer to the periventricular white matter lesions, which extend perpendicular to the lateral ventricles and/or callosal junction. These represent perivenular inflammation, and are hallmarks of multiple sclerosis (MS), a demyelinating disorder of brain, optic nerves and spinal cord. Dawson’s fingers, however, can be seen in conditions other than MS too. The commonest conditionContinue reading ““Dawson’s Fingers” on MRI Brain in Small Vessel Ischemia”

MRI Lesions Mimicking Dawson’s Fingers in a Case of Small Vessel ischemia


Dawson’s fingers are periventricular lesions in patients with multiple sclerosis (MS). These are flame-shaped lesions or finger like projections, perpendicular to ventricles and represent perivenular inflammation surrounding medullary veins. Dawson’s fingers are typically seen in patients with multiple sclerosis. However, here, I present a case of small vessel ischemia, whose MRI showed lesions mimicking Dawson’sContinue reading “MRI Lesions Mimicking Dawson’s Fingers in a Case of Small Vessel ischemia”
