title: Intracerebral haemorrhage and cerebral amyloid angiopathy: CT features with pathological correlation.
abstract: OBJECTIVE
  To review the computed tomography (CT) features of intracerebral haemorrhage pathologically proven to be associated with cerebral amyloid angiopathy in order to facilitate recognition of the presence of cerebral amyloid angiopathy in life.
  
  
  METHODS
  We prospectively collected the clinical and brain imaging records of patients dying following an intracerebral haemorrhage who underwent a post-mortem examination and were found to have cerebral amyloid angiopathy. We reviewed the brain imaging to highlight features of the haemorrhage and of the rest of the brain common to these cases.
  
  
  RESULTS
  Seven patients aged 60-86 years were examined over a 30-month period. On CT, the notable features were that the haemorrhages appeared large, lobar, often extended through the cortex to the subarachnoid space or into the ventricles, and were multiple and recurrent in patients who survived the initial bleed. The high density (blood) within the haematoma tended to sediment posteriorly.
  
  
  CONCLUSIONS
  There are features on CT of cerebral amyloid angiopathy associated with spontaneous intracerebral haemorrhage which should raise the possibility of this underlying diagnosis. We suspect this condition is under-recognized in life, and should perhaps be considered more widely.
