CSF Spaces in Idiopathic Normal Pressure Hydrocephalus:Morphology and Volumetry AJNR 19:1277-1284, 12851998., Kitagaki,H.,et al, 1998 See this aricle in Pubmed Article Abstract In patients with idiopathic NPH,the CSF volume was significantly increased in the ventricles and decreased in the superior convexity and medial subarachnoid spaces as compared with patients with other dementias.The sylvian CSF volume in patients with idiopathic NPH was significantly greater than in patients with Alzheimer disease.The volume of the basal cistern was comparable among the three groups.In several patients with idiopathic NHP,focally dilated sulci were observed over the convexity or medial surface of the hemisphere.Our results indicate that findings of enlarged basal cisterns and sylvian fissures and of focally dilated sulci support,rather than exclude,the diagnosis of shunt-responsive idiopathic NHP and suggest that this condition is caused by a suprasylvian subarachnoid block.
