Ventriculosubgaleal shunt: an effective CSF drainage in shunt disconnection.

A 4-year-old girl with a right ventriculoperitoneal shunt presented with a huge subcutaneous fluid collection in the scalp on the right side. There were no neurological symptoms or signs. On CT, a normal-sized ventricular system was seen. The shunt was disconnected distal to the antisiphon device and transmitted fluid into a subgaleal collection, which functioned as a reservoir for excess fluid. The ability of the subgaleal space to serve as a reservoir for cerebrospinal fluid is discussed.
