"It can be difficult to delineate from traumatic subarachnoid haemorrhage, particularly as in many instances the cause of head trauma may have been spontaneous subarachnoid (e.g. while driving)."
"Distinguishing between aneurysmal subarachnoid haemorrhage and traumatic non-aneurysmal subarachnoid haemorrhage is not always possible, and the trauma may have in reality been precipitated by a spontaneous aneurysmal haemorrhage (e.g. while driving)."
