The puzzle of spontaneous versus traumatic subarachnoid hemorrhage

Abstract

Subarachnoid hemorrhage (SAH) is a neurological emergency occurring frequently and has significant morbidity and mortality. Etiological classification divides it into traumatic and nontraumatic or spontaneous. Even though it has been referred that these are almost the same pathology, there is a slight difference between them regarding several aspects, such as epidemiological, pathophysiological, clinical, and diagnostic approach and treatment. These differences deserve detailed understanding to help physicians treat this disease more efficiently. We reviewed all available literature regarding these two types of SAH and tried to elicit differences between them with respect to etiology and treatment. The differences were made keeping in mind the utility of the same to a general physician so that rapid and informed decisions can be made at that level. Pathophysiological differentiation of these two diseases is of paramount importance, and etiological diagnosis determines prognosis. Knowledge of the same is essential and lifesaving.
