Congenital hydrocephalus due to villous hypertrophy of the telencephalic choroid plexuses

Abstract

A case of villous hypertrophy or bilateral papilloma of the choroid plexus of the lateral ventricles is reported. The child exhibited known features associated with overproduction of cerebrospinal fluid, hydrocephalus that was difficult to control, ascites after ventriculoperitoneal shunting, and relief after surgical removal of the papillomatous tissue. A unique feature is the complexity of the telencephalic choroid plexuses as shown by computerized tomography and ultrasound in the newborn period.
