Non-Anevrizmal Perimezensefalik Subaraknoid Kanama: 6 Olgu

Subarachnoid hemorrhage (SAH) is an important cause of mortality and morbidity in middle-age and elderly people. Although aneurysm ruptures are the most frequent causes of SAH, it cannot be identified in approximately 15% of the cases. However, the onset symptoms are similar, perimesencephalic non-aneurysmal SAH can be differentiated by benign prognosis from other forms. Its early diagnosis may prevent unnecessary neuroradiological and surgical procedures. In this study, 6 patients who admitted to Neurology Department with severe headache and detected hemorrhagic appearance around the mesencephalon (pretruncal) on computerized tomography were presented.
