There has been interval removal of the multiple nails penetrating the calvaria. Linear foci of hyperdense blood in both frontal lobes are consistent with haemorrhagic contusions along the tracts of the nails penetrating these regions. There is stable diffuse subarachnoid blood. No extra-axial collection or other new foci of intracranial haemorrhage. A few tiny locules of pneumocephalus overlie the left frontal lobe. A small fleck of bone fragment is again noted in the left temporal lobe. Normal grey-white matter differentiation is maintained. No intraorbital postseptal haematoma identified.
