Spontaneous regression of migrated ventriculoperitoneal shunt catheter from scrotum to peritoneum: a case-based review.

OBJECTIVE

The incidence of scrotal migration of a ventriculoperitoneal shunt (VPS) catheter is rare and may lead to life-threatening visceral complications. Management requires prompt removal of the migrated portion of the shunt and closure of the scrotal sac. We report an interesting case of a young child who presented with asymptomatic unilateral swelling of his scrotum secondary to a migrated VPS catheter. A repeat X-ray prior to his surgery to remove the migrated catheter showed that the entire length of the distal VPS catheter was back in the peritoneal cavity. In view of this unusual phenomenon, the case is discussed in corroboration with published literature.

METHODS AND

RESULTS

A systematic search of publications in the English language is performed in PubMed and Google Scholar. Our findings show that there are 49 reported cases (including our patient) of scrotal migration of shunt catheters in patients less than 18 years old. There is only 1 other case of spontaneous resolution of shunt catheter from the scrotum. Favoured management of choice is repositioning the distal shunt catheter back into the peritoneal cavity and herniotomy in the same setting, if possible. Overall, the literature suggests this is a shunt-related complication that has a good prognosis if intervention is timely.

CONCLUSION

Scrotal migration of a VPS catheter is a rare but potentially life-threatening complication in children. Our case report highlights the role of updated preoperative imaging and the need for consistent long-term shunt surveillance in children.
