Background
Non-traumatic, spontaneous subarachnoid hemorrhage occurs in approximately 85% of cases where there is a ruptured saccular aneurysm. An additional 10% of cases arise from non-aneurysmal peri-mesencephalic hemorrhages.
Case presentation
We report a rare case of a young female, with underlying Evans syndrome, who was initially thought to have non-hemorrhagic stroke, eventually diagnosed having isolated non-traumatic, non-aneurysmal convexal subarachnoid haemorrhage.
Conclusions
Spontaneous non-traumatic, non-aneurysmal convexal subarachnoid hemorrhage is a rare entity - of which there are multiple possible etiologies.
