Dandy-Walker Malformation
What is Dandy-Walker Malformation?
Dandy-Walker Malformation is a rare congenital brain malformation in children that involves the cerebellum.
The cerebellum is part of the brain responsible for motor coordination and balance. It affects the growth and development of the cerebellum. It results in an abnormally large head size, hydrocephalus (buildup of fluid in the brain), developmental delays, and other neurological symptoms.
What Causes Dandy-Walker Malformation?
Abnormality of the brain results in hydrocephalus and malformations of parts of the brain. Genetic mutations or environmental factors during fetal development can cause the condition, such as:
- Viral Infections
- Alcohol Consumption
- Drug Use
Signs & Symptoms
Common signs and symptoms of Dandy-Walker malformation include:
- Enlarged head circumference
- A bulge on the back of the skill (known as a "mound")
- Ridge at the back of the head
- Facial asymmetry
- Seizures
- Developmental delays in motor skills
- Intellectual disability
- Hearing loss
- Vision impairments
- Blindness
Risk Factors
Several risk factors are linked to the development of Dandy-Walker malformation in children. These include:
- Genetic factors: A family history of disorder that involves the central nervous system.
- Maternal health during pregnancy: Illnesses such as German measles, diabetes, and lupus can increase the risk for Dandy-Walker malformation.
- Infections during pregnancy: Infections in the mother, such as rubella or toxoplasmosis.
- Exposure to certain medications or toxins: Exposure to medications such as anticonvulsants and alcohol.
- Prematurity: Babies born prematurely can develop this condition
Diagnosis
Your health care team can diagnose this condition through a physical examination and imaging tests. Common tests include MRI, CT scans, or ultrasounds, which help evaluate the brain and identify the condition.
