[Analysis of imaging features of age-related cerebral small vessel disease with idiopathic normal pressure hydrocephalus].

To explore the imaging features in age-related cerebral small vessel disease (ArCSVD) with idiopathic normal pressure hydrocephalus (INPH). Ten cases of age-related cerebral small vessel disease (CSVD) with idiopathic normal pressure hydrocephalus admitted to the Third Affiliated Hospital of Sun Yat-sen University from December 2015 to March 2020 were retrospective analyzed, all patients met the inclusion and exclusion criteria, and completed the head Magnetic resonance angiography plain scan, T2 fluid attenuated inversion recovery and Susceptibility Weighted Imaging sequence. Deep marrow venous signs (DMVs), INPH severity (DESH score), cortical/subcortical and deep microhemorrhages (CMBs) statistics, paraventricular and deep white matter damage (WMH) severity and CSVD imaging burden score were acquired, and correlations of DMVs and DESH scores with CMBs, WMH and Burden scores were evaluated using Spearman correlation analysis. DMVs and DESH scores were significantly and positively correlated (=0.965 9, 0.000 1). DMVs and DESH scores were not significantly correlated with cortical/subcortical CMBs and deep CMBs. Likewise, DMVs and DESH scores were not significantly correlated with deep WMH. The WMH score of paraventricular of the 10 cases was 3 points, and the Burden score was 4 points. DMVs may be an indicator of the severity of ArCSVD with INPH, due to the small sample size of the current study, more cases are needed for further verification.
