WebShare: The Dandy-Walker malformation is a congenital (present at birth) defect affecting the cerebellum, the back part of the brain that controls movement, behavior and cognitive ability. Dandy-Walker can cause obstruction of the normal drainage of cerebrospinal fluid (CSF), resulting in a build-up of CSF and a condition called hydrocephalus. WebHydrocephalus is an abnormal build-up of cerebrospinal fluid(CSF) within and around the brain, which can be due to excess fluid production, obstruction to its flow, and …

In Stage I (prior to 1950), 2 systems of classifying hydrocephalus were proposed, namely Dandy's classifications of communicating and noncommunicating hydrocephalus ... WebThe diagnostic criteria of IIH are well known and have evolved since Dandy's initial description in 19374; they include a CSF opening pressure of ≥25 cm H 2 O .3 However, these criteria recommend imaging only to exclude a venous sinus thrombosis in patients without the typical IIH phenotype (obesity and female sex). We feel, however, that it ... WebThe CSF index is, therefore, an indicator of the relative amount of CSF IgG compared to serum.
