Dandy-Walker malformation affects brain development, primarily development of the cerebellum, which is the part of the brain that coordinates movement. Dandy-Walker complex is a group of disorders that affect the development of the brain. The changes in brain development are present from birth (congenital). PDF | RIASSUNTO.

SUMMARY Dandy-Walker syndrome is a particular form of hydrocephalus whose main feature is the transformation of the IV ventricle into a large cyst, which occupies almost the whole of the posterior fossa; the latter, owing to the lifting of the tentorium cerebelli and bulging of the occipital bone, is enlarged.
The underlying cause may be a dysfunctional molecular mechanism in the primary cilia structures of the cellorganelles which are present in many cellular types throughout the human body.

The DWC constitutes complete or partial agenesis of the vermis, cystic dilatation of the fourth ventricle with upper displacement of the lateral venous sinuses and tentorium. Dalker is intended for use primarily by physicians and other professionals concerned with genetic sindrome dandy walker, by genetics researchers, and by advanced students in science and medicine.
While rare, hearing aindrome vision problems can be features of this condition. The DWS malformation is the most severe presentation of the syndrome. The fourth ventricle is only mildly enlarged and there is mild enlargement of the posterior fossa. Dandy-Walker malformation is defined by hypoplasia and upward rotation of the cerebellar vermis and cystic dilation of the fourth ventricle.
There are three subtypes which affect multiple organs to varying degrees, but the fundamental abnormalities involve the cerebellum  which controls muscle coordination. A case report and literature review”.
Beales; Nicholas Katsanis September Prenatal diagnosis of congenital anomalies. The adjacent third and fourth ventricles are often affected, which awlker alter the flow of cerebrospinal fluidincrease intracranial pressureand lead to multiple other brain function problems. A special tube shunt to reduce intracranial pressure may be placed inside the skull to control swelling. Retrieved from ” https: Specialised Social Services Eurordis directory.
The pathogenesis is incertain; it is generally agreed that it is originated from a developmental disorder brought about by the non-opening of the foramina of Luschka and Magendie.
The abnormally high position of dandt transverse sinuses, as seen in the X-ray of the skull or in the sinugram, is considered a pathognomonical sign.
Dandy—Walker syndrome is one such disease, part of an emerging class of diseases called ciliopathies. Arnold-Chiari malformation, Dandy-Walker syndrome, sinfrome cyst of the cerebellum and syringomyelia.

Stationary Office, Londres, This often involves hydrocephalus and complications due to associated genetic conditions, such as Spina Bifida.

Children with Dandy—Walker malformation often have delayed development, particularly a delay in motor skills such as crawling, walking, and coordinating movements. The syndrome can appear dramatically or develop unnoticed. Sindrome dandy walker malformation appears to be the fundamental fault.
In older children, symptoms of increased intracranial pressure such as irritabilityvomitingand convulsions and signs of cerebellar dysfunction such as unsteadiness and lack of muscle coordination or jerky movements of the eyes may occur. There are, at present, three identified types of Dandy—Walker complexes. Full text available only in PDF format.

Services on Demand Journal. Currarino syndrome Diastomatomyelia Syringomyelia. The Dandy—Walker complex is a genetically sporadic disorder that occurs one in every 30, live births. There is no reference in the literature to Spitz’s operation, which is, in our opinion, the best treatment.
