Virchow-Robin spaces (VRS) are perivascular spaces surrounding the perforating cerebral arteries or arterioles.1,2 They distribute throughout the subarachnoid space to the brain parenchyma. Solutes from the brain parenchyma and lymphatics are drained into VRS, but VRS themselves do not have direct communication with the subarachnoid space.3 Dilated VRS (dVRS) are easily detectable by magnetic resonance imaging (MRI), usually in the basal ganglia (BG) at the level of the anterior commissure and in the deep white matter (WM), along the penetrating vessels.4 They appear as non-enhancing, high T2 and low T1 signals with iso-signal intensities Is the Severity of Dilated Virchow-Robin Spaces Associated with Cognitive Dysfunction?
