Dandy–Walker malformation (DWM), also known as Dandy–Walker syndrome (DWS), is a rare congenital brain malformation in which the part joining the two hemispheres of the cerebellum (the cerebellar vermis) does not fully form, and the fourth ventricle and space behind the cerebellum (the posterior fossa) are enlarged with cerebrospinal fluid.
Craniosynostosis-Dandy-Walker malformation-hydrocephalus syndrome (HCDPH1, also known as Sagittal craniosynostosis, Dandy-Walker malformation and hydrocephalus, Dandy-Walker malformation with sagittal craniosynostosis and hydrocephalus, Braddock-Jones-Superneau syndrome, or simply Hydrocephalus, autosomal dominant) is an autosomal dominant syndrome characterized by sagittal craniosynostosis ...
A wide variety of symptoms are potential clinical features of ciliopathy. The signs most exclusive to a ciliopathy, in descending order of exclusivity, are: [8]: 138 Dandy–Walker malformation (cerebellar vermis hypoplasia, usually with hydrocephalus) Agenesis of the corpus callosum; Situs inversus; Posterior encephalocele; Polycystic kidneys
Walker–Warburg syndrome (WWS), also called Warburg syndrome, Chemke syndrome, HARD syndrome (Hydrocephalus, Agyria and Retinal Dysplasia), Pagon syndrome, cerebroocular dysgenesis (COD) or cerebroocular dysplasia-muscular dystrophy syndrome (COD-MD), [1] is a rare form of autosomal recessive congenital muscular dystrophy.

Dandy Walker malformation is a relatively common congenital brain malformation with a prevalence of 1:30,000 live births. [17] Dandy Walker malformation is characterized by enlarged posterior fossa and in which the cerebellar vermis is completely absent, or present in a rudimentary form, sometimes rotated accompanied by an elevation of the ...
Cranial dysplasias associated with 3C syndrome are also reflected in the brain. Besides the cerebellar hypoplasia, cysts are commonly found in the posterior cranial fossa, the ventricles and the cisterna magna are dilated/enlarged, and Dandy–Walker malformation is present. These are reflected in the developmental delays typical of the disease.
MVD, which is frequently fatal and is related to the much better-known Ebola virus, is sometimes known as "bleeding eye disease" because it damages people's blood vessels, causing them to bleed ...
The symptoms depend on the cause of the blockage, the person's age, and how much brain tissue has been damaged by the swelling. [ 11 ] Hydrocephalus ex vacuo is a condition in which there is ventriculomegaly due to loss of brain volume which then results in a subsequent increase in CSF. [ 19 ]
