Abstract
We describe a boy with asymmetrical hydrocephalus in whom a marked hemiparesis of recent origin resolved completely following insertion of a shunt. In 2 children with shunted obstructive hydrocephalus due to a midline tumour a newly developed hemiparesis improved markedly in one and resolved in the other case subsequent to revision of a blocked shunt. A hemiparesis should therefore not necessarily be attributed to assumed progression of an underlying disease. Other unusual symptoms of hydrocephalus or shunt dysfunction reported in childhood as well as possible causes of hemiparesis in shunted patients are listed.
