Extradural haematoma
• Any patients• Usually high impact• Usually associated fracture• Arterial bleed – peels dura off skull under
pressure• Usually clinical deterioration <4 hours post
injury

What else?
• Thickness – in mm at widest point• Midline shift – in MM at most shifted point• Effacement of ventricles

Subdural haematoma
• Older people• Often minor injury/shearing force (25% no
trauma Hx)• Brain shrinks with age, subdural veins under
some tension• Slow bleed – often present weeks-months
later• Dcreased LOC, headache, ataxia, cognitive
dysfunction, Motor deficit, aphasia

What else?
• Thickness/Midline shift/ventricles• Age: Acute <4 days, subacute 4-21 days,
Chronic >21 days

Subarachnoid haemorrhage
• Can be traumatic, aneurysmal, hypertensive• Sudden onset severe headache +/- neurology• 80% from ruptured aneurysm• CTB is 100% sensitive in first 6 hours*
