Vulvar migration of the peritoneal end through the inguinal canal in a female infant: An unusual complication of the ventriculo-peritoneal shunt: A case report and review of literature

Unusual presentation of a common neurosurgical shunt procedure in an adult patient

Ventriculoperitoneal shunt surgery is one of the treatments of hydrocephalus. It involves placing a shunt from the cerebral ventricles to the peritoneum serving as a drainage point. Infection and catheter blockage are some of the possible complications resulting from this procedure. In some cases, other incidents such as peritoneal shunt migration have also been described. Here, we present the case of a 73-year-old male patient treated with ventriculoperitoneal shunt for a normal pressure hydrocephalus. After an initial blockage of the ventricular catheter, a revision surgery was performed with only mild improvement of his neurological symptoms. A repeat shunt series X-ray showed a migration of the distal catheter into the scrotum through an inguinal hernia. He was successfully treated with a laparoscopic repair of the inguinal hernia and repositioning of the distal catheter into the peritoneal cavity. Scrotal migration and hydrocele are unusual presentations and complications of ventriculoperitoneal shunts. Close follow-up of patients with a ventriculoperitoneal shunt should be performed if they experience worsening of their neurological symptoms. Shunt integrity should be assessed and any complications should be managed.

Rare complication of ventriculoperitoneal shunt. Early onset of distal catheter migration into scrotum in an adult male: Case report and literature review

•

Cases of scrotal migration of distal catheter in adults are rare.

•

There have been no reports for scrotal migration in adults at an early onset.

•

Early detection of migration of distal catheter prevents shunt malfunction.

•

Prompt surgical management of catheter repositioning is recommended.

Introduction

The role of shunt placement is to divert cerebrospinal fluid from within the ventricles to an alternative location in the setting of hydrocephalus. One of the rare shunt complications is distal catheter migration, and various body sites have been reported, including the scrotum. Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis. Furthermore, there has not been a case reported for scrotal migration in an adult at an early onset.

Presentation of case

65-year-old male underwent shunt placement for normal-pressure hydrocephalus-like symptoms. On post-operative day seven patient developed right testicular edema, for which ultrasound was performed, revealing hydrocele along with the presence of distal catheter in the scrotum. On post-operative day nine patient underwent distal catheter trimming via laparoscopic approach with general surgery, with post-operative imaging showing satisfactory location of distal catheter in the peritoneal cavity.

Discussion/Conclusion

Early onset of distal catheter migration into scrotum in an adult male is a unique case, as most cases are reported in pediatric patients, and it is the first case reported in the English literature to have occurrence at an early onset during the peri-operative period. As our case demonstrates, early occurrence and detection of scrotal migration of the distal catheter prevent shunt malfunction. Prompt surgical management of catheter repositioning is therefore recommended to avoid the risk of further complications.
