[Dandy-Walker complex with multiple anomalies: report of one case].

A 3570 gram male newborn was born to a 29-year-old mother at the gestational age of 40 weeks with gross abnormalities of flexion contracture of third and fifth fingers and fourth toes bilaterally. After birth, cyanotic spell while feeding was found, and a series of examinations were done. The abnormalities were focused on brain echogram, computed tomogram and magnetic resonance imaging examination, which showed a large posterior fossa cyst, cerebellar hypoplasia complicated with multiple severe supratentorial anomalies, including marked ventricular dilatation, cerebral agyria, agenesis of corpus callosum, absence of thalamus and basal ganglion, and optic nerve atrophy. Clinically, the patient had neonatal seizure and high fever. The diagnosis of Dandy-Walker complex type A was made according to the new classification presented by Barkovick et al. in 1989.
