A large hyperdense collection is seen along the right convexity. Areas of relative
hypodensity are present within the collection. Significant midline shift is present
with subfalcine herniation.
The extraaxial hematoma (with areas of hyperacute bleeding ) is also causing
transtentorial herniation as evidenced by the obliteration of the basal cisterns.
