Subarachnoid haemorrhage - MCA aneurysm rupture

Case contributed by Dr Ian Bickle

Presentation

Terrible headache of acute onset. GCS reduced.

Patient Data

Age: 40 years
Gender: Male

Diffuse sub-arachnoid haemorrhage throughout both cerebral hemispheres.

Large haematoma centred on the M1-M2 segment of the right middle cerebral artery. A 'filling defect' is visible within the clot, suggesting the culpable aneurysm. 

The basal cisterns contain blood as does the ventricular system.

Mild left temporal horn dilatation.

Case Discussion

Typical appearances of a subarachnoid haemorrhage.

The location of the haematoma is highly suggestive of a MCA aneurysm, which was subsequently proven on catheter angiography.

The aneurysm underwent surgical clipping.
