Umbilical CSF fistula: a rare complication of ventriculoperitoneal shunt.

An umbilical CSF fistula following a ventriculoperitoneal shunt is an extremely rare complication. We report a 28-year-old man who presented with leak of clear fluid from the umbilicus, one month after a ventriculo-peritoneal shunt revision. Shuntogram revealed communication between umbilicus and abdominal end of the catheter. He was managed successfully with shunt exteriorization, antimeningitic treatment, and later shunt re-insertion.
