Axial MRI showing typical findings of idiopathic NPH
Axial MRI showing typical findings of idiopathic NPH
Axial MRI FLAIR sequences demonstrating features of NPH including the features of DESH: enlarged ventricles (arrows), enlarged Sylvian fissures (dashed arrows), entrapped fluid in sulci (thick arrows; not to be mistaken for atrophy), and high tight sulci (arrowhead).
MRI: magnetic resonance imaging; NPH: normal pressure hydrocephalus; FLAIR: fluid-attenuated inversion recovery; DESH: disproportionately enlarged subarachnoid space hydrocephalus.
