Teaching Neuro Images : MRI-visible Virchow-Robin perivascular spaces in cerebral small-vessel disease

MRI-visible perivascular spaces (PVS) in centrum semiovale white matter (CS) have been proposed as a novel neuroimaging marker for cerebral amyloid angiopathy (CAA).[1,2] Progressive beta -amyloid deposition in small cortical and leptomeningeal arteries in CAA may gradually impair perivascular drain...

Zusammenfassung:MRI-visible perivascular spaces (PVS) in centrum semiovale white matter (CS) have been proposed as a novel neuroimaging marker for cerebral amyloid angiopathy (CAA).[1,2] Progressive beta -amyloid deposition in small cortical and leptomeningeal arteries in CAA may gradually impair perivascular drainage and cause retrograde PVS dilation.[1,2]
