Convexal subarachnoid haemorrhage – http://id.who.int/icd/entity/352591452

This is bleeding into the subarachnoid space – the area between the arachnoid membrane and the pia mater surrounding the brain – but only intrasulcal bleeding within the hemispheric convexities. It results from neither aneurysm nor trauma.
