Extensive infarction in the MCA and ACA territory is visualised with large, diffuse areas of encephalomalacia and decreased density. No acute haemorrhage is seen. Expansion of brain parenchyma way beyond the former course of the right calvaria, in keeping with a space-occupying infarction due to extensive vasogenic edema.No signs of acute raised intracranial pressure, no midline shift, no other acute findings.
