Cystoperitoneal shunting for congenital arachnoid cysts.

Between 1980 and 1982, 8 children with congenital arachnoid cysts were treated at the University of Florida, 2 patients presented with unusual clinical syndromes, including isosexual precocity and a cephalic movement disorder. Cystoperitoneal shunting in combination with ventriculoperitoneal shunting for associated hydrocephalus was employed in the treatment of all supratentorial lesions, and proved to be a safe, efficacious mode of therapy.
