RT Journal Article SR Electronic T1 Hydrocephalus induced chorea JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr0820080788 DO 10.1136/bcr.08.2008.0788 VO 2009 A1 N C Voermans A1 P J Schutte A1 B R Bloem YR 2009 UL http://casereports.bmj.com/content/2009/bcr.08.2008.0788.abstract AB Chorea can result from many causes, and the diagnostic workup can be challenging. Although often accompanied by other extrapyramidal symptoms, hydrocephalus has not been mentioned as a possible cause of chorea to date. Here we report an unusual case of chorea secondary to normal pressure hydrocephalus, which clearly improved after shunt placement.
