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 ...
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 ...

Dandy-Walker malformation is also occasionally seen in Ellis–Van Creveld syndrome, which is characterized by heart defects and malformed alveolar ridge. [5] Many disorders include the Dandy–Walker phenotype and thus it is not pathognomonic for 3C syndrome. [10] CHARGE syndrome can also be misdiagnosed. This is because both CHARGE syndrome ...
Developmental disorders including neural-tube defects, arachnoid cysts, Dandy–Walker malformations, and Arnold–Chiari malformations can cause primary hydrocephalus. Dandy-walker malformations and Arnold-Chiari malformations lead to structural abnormalities in the brain, which disrupts the flow of CSF and causes hydrocephalus. [26] [27]
The abnormalities of the leptomeninges during fetal development due to neurocutaneous melanosis may be the cause of this increased incidence of the Dandy-Walker malformation. The development of hydrocephalus is the most common symptom associated with a combination of neurocutaneous melanosis and a Dandy-Walker malformation, occurring in about ...
Marden–Walker syndrome (MWS) is a rare autosomal recessive congenital disorder. [ 1 ] [ 2 ] It is characterized by blepharophimosis , microcephaly , micrognathia , multiple joint contractures , arachnodactyly , camptodactyly , kyphoscoliosis and delayed motor development and is often associated with cystic dysplastic kidneys , dextrocardia ...
