Asymptomatic Dandy-Walker syndrome in an adult

This 34 years old man presented with moderate and persistent headache occurring 48 hours following Benin head injury. There were no symptoms of increased intracranial pressure. Neurological examination was unremarkable without cerebellar ataxia or psychomotor retardation .the patient was submitted to CT scan and magnetic resonance imaging (MRI) of the brain that revealed agenesis of cerebellar vermis and large posterior fossa cyst communicating with the enlarged fourth ventricle suggestive of Dandy-Walker malformation without hydrocephalus. He was managed conservatively and he is doing well following 2 years ago. The Dandy-Walker syndrome (DWS) is a rare posterior fossa malformation and more rarely observed in adults. This case is unique in that the patient has been entirely asymptomatic with this abnormality since birth. The preserved cortical cytoarchitecture and the rarity of additional neurodevelopmental changes in DWS adults may explain the mild or absence of clinical expression, compared with DWS infants.
