title: Scrotal migration of the peritoneal catheter of a ventriculoperitoneal shunt in a 5-year-old male. Case report.
abstract: A 5-year-old male presented with scrotal migration of the catheter from a ventriculoperitoneal shunt manifesting as left scrotal swelling 4 months after implantation. Surgical obliteration of the patent peritoneal processus vaginalis that forms a corridor from the peritoneum to the scrotum was performed to avoid shunt malfunction. Review of the 26 reported cases including the present case revealed that most patients were up to 18 months old. Our patient was the oldest. Migration tended to occur within 6 months after implantation (mean 3.8 months, median 1.0 month). Involvement of the right side of the scrotum was prevalent (23 of 26 cases). Patent processus vaginalis and small peritoneal cavity probably contribute to scrotal catheter migration.
