title: Minimally conscious state after ruptured giant basilar aneurysm.
abstract: OBJECTIVE
  To report the clinical and radiologic findings in a case of transient minimally conscious state after rupture and coiling of a giant basilar aneurysm.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Neuroscience intensive care unit.
  
  
  METHODS
  A 44-year-old man who developed a transient minimally conscious state in association with perianeurysmal edema in the rostral brainstem and thalamus after rupture and coiling of a giant basilar artery aneurysm.
  
  
  METHODS
  Correlation of clinical and magnetic resonance imaging findings.
  
  
  RESULTS
  A minimally conscious state and bilaterally symmetric vasogenic edema of the rostral brainstem and thalamus developed 2 days after endovascular aneurysm coiling. The clinical and radiologic abnormalities improved significantly and in parallel during the following 4 weeks.
  
  
  CONCLUSIONS
  Perianeurysmal vasogenic edema in the brainstem and thalamus can develop after rupture and coiling of a giant basilar artery aneurysm. This process can be transient and can produce dramatic alterations in consciousness that later resolve.
