Intraventricular migration of VP shunt.

The proximal migration of a ventriculoperitoneal shunt into the ventricles is very rare. Only 5 cases have been previously reported [4, 8, 10, 11]. We believe that this unusual phenomenon has not been well-studied in the literature. We report a case of a 16-month-old baby girl who suffered a shunt malfunction due to complete migration of the VP shunt into the lateral ventricle. This case and the other 5 cases are studied, and a possible cause is hypothesized. The group of patients at risk is also identified and methods of management are reported.
