Patient Data

Age: 70 years
Gender: Male

Bilateral acute on chronic subdural haematomas illustrating a 'layered' effect to the variable ages of blood.

The equal sized bilateral subdurals has resulted in no real midline shift or mass effect.


Case Discussion

Haematoma collecting, usually following trauma, between the meningeal and arachnoid layers of the dura.

May cross sutures but not dural attachments.

Bilateral subdural haematomas are less common than unilateral.

Subdurals may contain: hyperacute, acute, subacute and chronic haematoma

Half of subdural haematomas are due to rupture of a bridging vein and the other half due to torn cortical arteries.
