DOWN SYNDROME WITH CONGENITAL HYDROCEPHALUS

Down syndrome is the most frequent genetic cause of mental retardation. Although usually presenting dysmorphic features and organ malformations, it is rarely associated with congenital hydro- cephalus. The case of male neonate whose hydrocephalus was detected since the pregnancy and was dis- covered to have the syndrome at birth is reported. Chromosomal analysis confirmed the genetic disorder, and hydrocephalus was treated with ventriculoperitoneal shunt because of abnormal increase of head cir- cumference. The patient has been accompanied and his development is considered normal when com- pared to the expected for those affected by the syndrome.
