Dandy-Walker Syndrome is a congenital brain defect in humans characterized by malformations to the cerebellum, the part of the brain that controls movement, and to the ventricles, the fluid-filled cavities that surround the cerebellum. The syndrome is named after physicians Walter Dandy and Arthur Walker, who described associated signs and symptoms of the syndrome in the 1900s. filexlib. The direct cause of Dandy Walker syndrome is not known or idiopathic in sense. This has been the major report among cases of Dandy Walker syndrome. But according to studies, the condition is considered as autosomal recessive. Environmental factors have also been noted to be part as a predisposing factor for Dandy Walker syndrome. Dandy-Walker syndrome is important because autosomal recessive inheritance is assumed for Joubert's syndrome; however, normal cerebellar hemispheres can be demon- strated on CT in comparison to the total cerebellar hypo- plasia of the Dandy-Walker syndr~me.'~ Dandy-Walker syndrome with evolutive hydrocephalus requires neurosurgery.
Dandy-Walker malformation affects brain development, primarily development of the cerebellum, which is the part of the brain that coordinates movement. In individuals with this condition, various parts of the cerebellum develop abnormally, resulting in malformations that can be observed with medical imaging. The central part of the cerebellum
5. Classification Dandy-Walker malformation: increase of the posterior fossa, complete or partially agenesis of the cerebellar vermis, and a tentorium elevation. 6. Variant of Dandy-Walker: hypoplasia of the cerebellar vermis in different degrees with or without increase of the posterior fossa. Dandy-Walker syndrome (DWS) affects the posterior cranial fossa resulting in characteristic dysmorphic facial and body features. Scoliosis is not typically reported as an extracranial manifestation of this condition. We present a 12-year-old female patient who developed a right thoracic scoliosis measuring 60° with increased lumbar lordosis.
Dandy-Walker malformation (DWM) is the most common congenital malformation of the human cerebellum, affecting 1/5000 live births. DWM is characterized by a hypoplastic cerebellar vermis, which is rotated away from the brainstem, and a significantly enlarged fourth ventricle in an enlarged posterior skull ( Millen and Gleeson, 2008 ).
El síndrome de Dandy-Walker se asocia a menudo con trastornos de otras áreas del sistema nervioso central, incluyendo la ausencia del cuerpo calloso (el área compuesta por fibras nerviosas que conectan a los dos hemisferios cerebrales) y malformaciones cardiacas, faciales, de las extremidades y de los dedos de las manos y los pies.

Symptoms of Dandy-Walker syndrome vary from person to person, but developmental troubles in infancy and increased head circumference due to hydrocephalus may be the first—or only—signs. Some other common symptoms of Dandy-Walker syndrome include: 3 . Slowed motor development: Kids with Dandy-Walker syndrome often experience delays in
Dandy-Walker malformation, also known as Dandy-Walker syndrome, is a rare congenital brain malformation in which the part joining the two hemispheres of the cerebellum does not fully form, and the fourth ventricle and space behind the cerebellum are enlarged with cerebrospinal fluid. Most of those affected develop hydrocephalus within the first year of life, which can present as increasing head size,
