Dandy-Walker Malformation can cause swelling of the brain.

This refers to a brain malformation that occurs during embryonic development of the cerebellum and 4th ventricle. Symptoms may include developmental delay, low muscle tone (hypotonia) or spasticity, and poor coordination and balance. In addition, DWM is sometimes (20-80%) associated with hydrocephalus, in which blockage of the normal flow of spinal fluid leads to excessive amounts of fluid accumulating in and around the brain. This leads to abnormally high pressure within the skull and swelling of the head, and can lead to neurological impairment.
