title: Development of cerebral infarction shortly after intracerebral hemorrhage.
abstract: OBJECTIVE
  Cerebral infarction (CI) occurring soon after intracerebral hemorrhage (ICH) has been rarely reported. The purpose of the present study was to characterize this condition and discuss the possible pathophysiology.
  
  
  METHODS
  We retrospectively studied 6 patients who developed CI within 10 days after the onset of ICH.
  
  
  RESULTS
  The initial ICHs were located in the putamen (n=3), thalamus (n=2) and cerebellum (n=1), and were considered to be caused by hypertension in all of the patients. They showed sudden worsening (n=4) or change in neurologic symptoms (n=2) within 10 days after the initial ICH. Follow-up imaging revealed corresponding lacunar (n=2) and territorial (n=4) infarcts. Possible factors related to the development of new CIs included mechanical compression of cerebral vessels (n=2), dehydration (n=4), hypotension (n=2), infection (n=2) and concomitant small-vessel pathology (n=2).
  
  
  CONCLUSIONS
  ICH may predispose certain patients to the development of infarcts through a combination of mechanisms, including mechanical compression of cerebral vessels, hemodynamic instability, inflammation and concomitant small-vessel pathology.
