Marked dilatation of the supra- and infratentorial ventricular system with widening of the basal cisterns, prominent cortical sulci, Sylvian fissures and basal cisterns. compartmentalization of the left frontal horn is also noted. A relatively large area of altered MR signal is seen involving the choroid plexus within the left lateral ventricle displaying predominantly hyperintense T1WI as well as hypointense T2WI rim and hyperintense FLAIR signal with restricted diffusion with hypointense ADC signal (early subacute blood). Another smaller similar intraventricular blood is seen within the right lateral ventricle in dependent location.
Marked reduction of white matter volume with bilateral cerebral deep white matter and periventricular transependymal interstitial retrograde CSF permeation with left anterior frontal encephalomalacia. No midline shift. No extra axial masses or collections.
