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 ...
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.
[4] [5] 75% of children with 3C syndrome have Dandy-Walker malformation and hydrocephalus. [6] Signs and symptoms in other body systems are also associated with 3C syndrome. In the skeletal system, ribs may be absent, and hemivertebrae, syndactyly (fusion of fingers together), and clinodactyly (curvature of the fifth finger) may be present.

A variety of brain abnormalities are also associated with 13q deletion. They can include epilepsy, craniosynostosis (premature closing of the skull bones), spastic diplegia, cerebral hypotrophy, underdevelopment or agenesis of the corpus callosum, cerebellar hypoplasia, deafness, and, rarely, hydrocephalus, Dandy–Walker syndrome, and spina ...
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.

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 ...
