A late presentation of Dandy-Walker malformation and aortic coarctation

The Dandy-Walker malformation is a rare anomaly of the posterior cranial fossa. Concomitant brain or systemic malformations are frequent and can influence the outcome. Associated cardiac congenital defects usually induce a poor prognosis. We report a case of a 58-yearold man with hydrocephalus, in whom Dandy-Walker malformation was diagnosed, for the first time, after the demonstration of aortic coarctation. This association is very rare and only a few cases have been described; moreover, to our knowledge, this is the first description of this incidence in a middle-aged patient. The characteristic of diseases and physiopathologic features are discussed, focusing attention on the rare and late clinical manifestations.
