Can Dandy-Walker be seen on ultrasound?
Dandy-Walker malformation (DWM) is easily seen with obstetrical ultrasound and is usually diagnosed by 20 weeks’ gestation, but has been seen even earlier. The findings on ultrasound consist of a cyst in the cerebellum. There may or may not be other birth defects in the brain or in other organ systems.
How is Dandy Walker Syndrome diagnosed?
Dandy Walker malformation is diagnosed with the use of ultrasound, CT and MRI. Prenatal diagnosis of Dandy-Walker malformation is sometimes made by ultrasound or fetal MRI.
What is the difference between Dandy-Walker malformation and variant?
Dandy-Walker variant (DWv) is a less severe posterior fossa anomaly than the classic Dandy-Walker malformation (DWM) and is considered being on the lesser end of the disease spectrum in the Dandy-Walker continuum.
When can Dandy Walker syndrome be diagnosed?
Some experts have noted that it may be fully formed by the end of 16 weeks gestation. However, while Dandy-Walker malformation (DWM) has been diagnosed in the first trimester, a false-positive diagnosis can be made at gestational ages of less than 18 weeks.
How rare is Dandy-Walker syndrome?
Dandy-Walker malformation is estimated to affect 1 in 10,000 to 30,000 newborns.
Is Dandy-Walker Syndrome progressive?
The syndrome can appear dramatically or develop unnoticed. Symptoms, which often occur in early infancy, include slow motor development and progressive enlargement of the skull.
Is Dandy-Walker syndrome a birth defect?

What causes Dandy Walker syndrome?
Dandy Walker syndrome (DWS) is brought about by an abnormal brain development that caused the cerebellum to become defective or abnormally formed, specifically at the posterior part of the brain.
What does Dandy-Walker syndrome stand for?
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.
What is Dandy- Walker syndrome?
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,…
What is Dandy Walker malformation?
