Virchow-Robin Spaces

Virchow-Robin Spaces

Virchow-Robin spaces (VRS) are perivascular, fluid-filled canals that surround perforating arteries and veins in the parenchyma of the brain. VRS are extremely small and can usually only be seen on MR images when dilated. While many normal brains will show a few dilated VRS, an increase in dilated VRS has been shown to correlate with the incidence of several neurodegenerative diseases, making the spaces a popular topic of research.
