Poster Abstract
We report a case of a 15-year-old male who presented to the Emergency Department(ED) for agitation and was subsequently diagnosed with Dandy-Walker malformation (DWM). DWM is a rare congenital abnormality of the posterior fossa characterized by hypoplasia of the cerebellar vermis, cystic dilation of the fourth ventricle, and enlargement of the posterior fossa. It is typically diagnosed during infancy due to hydrocephalus, developmental delay, or neurologic abnormalities. Late presentations in adolescence are uncommon and may occur incidentally during evaluation for unrelated conditions.
