Dandy?Walker Malformation is a rare, congenital brain abnormality that affects the development of the cerebellum (the area controlling balance and coordination) and the fluid-filled spaces surrounding it. The abnormality causes a buildup of cerebrospinal fluid (CSF).
read more about dywalker malformation ...The cause is a congenital defect that occurs during foetal brain development, often related to environmental or genetic factors. The malformation involves enlargement of the fourth ventricle (a fluid-filled cavity) and a partial or complete absence of the cerebellar vermis (the central part of the cerebellum).
This severe structural anomaly disrupts fluid circulation and nerve signaling. It is often associated with other structural abnormalities of the brain and body, making it a serious diagnosis.
Symptoms in infants include an abnormally large head size, slow motor development (sitting up, walking), and signs of increased pressure inside the skull (vomiting, irritability). In older children, symptoms include poor coordination, an unsteady gait, and abnormal muscle stiffness. The severity of symptoms depends on the degree of the structural abnormality and the speed of fluid accumulation.
Dandy?Walker Malformation directly impacts eye health due to the pressure on the brain and cerebellar damage. Patients frequently develop nystagmus (uncontrolled eye movements) and severe strabismus (eye misalignment), affecting visual tracking and clarity. These symptoms are caused by damage to the nerve centers in the brain that regulate eye movement and coordination.
Diagnosis is often made during pregnancy via ultrasound or immediately after birth. Magnetic Resonance Imaging (MRI) is the definitive diagnostic tool, providing detailed images of the enlarged ventricle and the cerebellar structure. Computed Tomography scans are also used to assess the severity of the hydrocephalus (fluid buildup).
The necessary treatment is often the placement of a shunt. A shunt is a flexible tube used to drain the excess cerebrospinal fluid (CSF) away from the brain to another area of the body (like the abdomen) to relieve pressure. Relieving this pressure is vital to prevent further brain damage and manage symptoms.
No, the brain malformation is permanent, but the symptoms caused by excess fluid (hydrocephalus) are manageable with a shunt.
Yes, most individuals with the malformation have some degree of intellectual or learning disability.
No, the malformation is usually a spontaneous congenital defect, not an inherited genetic disorder.
Consult a pediatric neurologist for delayed motor skills or increasing head size in infants. This condition often causes "Nystagmus" or "Papilledema" (swelling of the optic nerve) due to high brain pressure. Lifelong monitoring of the shunt is necessary.
