Cerebrospinal fluid (CSF) diversion by shunting provides effective management of hydrocephalus.1 However, complication rates of CSF shunts range from 5% to 50%.1–3 Most common are shunt infections and mechanical failures; these may lead either to underdrainage (with re-emergence of hydrocephalus) or overdrainage (with intracranial hypotension and its potential complications, eg, subdural hematoma).3 ,4 Misplacement and migration of shunt catheters may cause seizures, intracerebral haemorrhage, and/or focal neurologic deficits, such as hemiparesis.1 ,2 We report a case of hemichorea after CSF shunt placement, and review the literature on CSF shunt-related movement disorders.
