F: 1) right-sided frontal intracerebral white (hyperdense) area, 2) left-sided hyperdense areas in the sulci, 3) low density areas on the left side and 4) compression of the left ventricle and 5) midline shift to the right side 6) flattened sulci against inner skull 7) epidural changes omn the right side

INFO/WWW-LINKS General information: Fresh blood is high density compared with brain on CT and, at brain windows, appears white. As the clot absorbs, the lesion becomes isodens (2-3 weeks after bleeding) and, later, of low attenuation
Sites of intracranial heamorrhage/haematoma:
1) Between inner tabel and dura = extradural heamorrhage/haematoma
2) Between dura and arachnoid = subdural heamorrhage/haematoma
3) Between arachnoid and brain surface = subarachnoid heamorrhage/haematoma
4) Within brain = intracerebral heamorrhage/haematoma
5) Within ventricles = intraventricular heamorrhage/haematoma Rising intracranial pressure can be caused by e. g. head injury, meningoencephalitis, haemorrhage or cerebral oedema and tumour
Some more information according to cerebral infarction (stroke)

D: At brain windows evidence of Acute intracerebral haemorrhage 2) acute subarachnoid haemorrhage 3) infarction of the middle cerebral artery (low density areas) 4) compression of the left ventricle 5) midline shift to the right side 6) cerebral oedema 7) edidural haematoma
