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.
