Del Brutto OH, et al. - This study investigated if there exists any possible correlation between enlarged basal ganglia perivascular spaces (BG-PVS) and carotid siphon calcifications (CSC), used as a surrogate of intracranial atherosclerosis. Findings indicated that occurrence of both conditions may be explained by a common pathogenetic mechanism as it was observed that enlarged BG-PVS often coexisted with CSC.
