What is a common symptom of Dandy Walker malformation?

Dandy Walker malformation is a congenital brain malformation characterized by the enlargement of the fourth ventricle, cystic dilation of the cerebellar vermis, and the possible involvement of the posterior fossa. One of the hallmark symptoms associated with this condition is hydrocephalus, which can occur due to the obstruction of cerebrospinal fluid (CSF) pathways. The malformation can lead to an accumulation of CSF, increasing intracranial pressure and causing symptoms such as headaches, vomiting, and developmental delays.

While seizures, spasticity, and hypotonia can be associated with various neurological conditions, they are not as directly connected to Dandy Walker malformation as hydrocephalus. Hydrocephalus is particularly significant because it results from the structural abnormalities caused by the malformation, making it a defining and common symptom of this condition. Recognizing hydrocephalus as a primary symptom is crucial for proper diagnosis and management of patients with Dandy Walker malformation.
