title: Subarachnoid hemorrhage and extrapyramidal symptoms: a case report.
abstract: Parkinsonism may occur after brain lesions such as subarachnoid hemorrhage (1), hydrocephalus (2,3), slit ventricle (4), or shunt revision (5).Until now, pathogenesis remains unclear.
  
  
  
  Case Report.
  
  
  
  We described the case of a 53 years Caucasian male with subarachnoid hemorrhage after anterior communicating artery aneurysm rupture, with subsequent complications and early development of bilateral extrapiramidal symptoms. A DatSCAN showed an impairment of the nigro-sytriatal dopaminergic way. Levodopa therapy induced complete symptoms remission.
  
  
  
  Patient developed Parkinson Disease responding to Levodopa. Subarachnoid hemorrhage itself, shunt placement and revision, hydrocephalus, slit ventricle: all of these complications occurred and could be possible causes of shear, torsion, and ischemia of the nigrostriatal projection fibres.
