Abstract/OtherAbstract:
Nonaneurysmal subarachnoid hemorrhage (NA-SAH) constitutes a heterogeneous group of patients, both perimesencephalic (PMN-SAH) and non-perimesencephalic (nPMN-SAH). Despite many reports and case series, the etiology of NA-SAH remains uncertain. The differences in clinical course and outcome between PMN-SAH and nPMN-SAH are evident and have to be taken into consideration at the time of admission, as aggressive diagnostic evaluation and management are required for latter patient. In terms of diagnostic evaluation, the most important determination is to differentiate PMN-SAH from nPMN-SAH and aneurysmal SAH. PMN-SAH can be distinguished on CT in the majority of patients, but should be confirmed by a negative cerebral angiography. In addition, Convexal NA-SAH is another important subtype of NA-SAH associated with diverse etiologies and symptoms, although prognosis is generally favorable.
