Scrotal migration of ventriculoperitoneal shunts.

Ventriculoperitoneal diversion of cerebrospinal fluid in infants and children with hydrocephalus has become the procedure of choice over the last 15 years. It has replaced ventriculoatrial shunts, resulting in a marked decrease in the complication rate after such procedures. Four cases of migration of the shunt tip through patent processus vaginalis resulting in scrotal hydrocele are presented.
