title: Traumatic intracranial displacement of the ventriculoperitoneal valve chamber in a child-a report of 2 cases.
abstract: We present two cases of traumatic intracranial migration of the ventriculoperitoneal (VPS) valve chamber without malfunction of the system. In both patients, a shunt reservoir was surgically repositioned without a burr hole expansion and with no implantation of a new VPS system. We discuss a role of a head trauma and repeated valve palpation in this rare complication.
