Interval left hemicraniectomy demonstrated with subsequent improvement of the previously demonstrated right sided midline shift. The is currently a region of postsurgical pneumocephalus along the left posterior temporal convexity with tiny locules of air tracking towards the left transverse dural venous sinus. There is a shallow rind of acute cortical haemorrhage adjacent to the region of left posterior temporal pneumocephalus, extending towards the left tentorium cerebelli.
The established left middle cerebral artery territory infarct is again demonstrated. More extensive haemorrhagic transformation is currently demonstrated within the infarct distribution, particularly along the more peripheral aspect of the vascular territory.
