Perimesencephalic nonaneurysmal subarachnoid hemorrhage: review of the literature

T H Schwartz et al. Neurosurgery. 1996 Sep.

Abstract

Objective: A critical review of the literature on the incidence, presentation, diagnosis, and prognosis of perimesencephalic nonaneurysmal subarachnoid hemorrhage.

Methods: Review of the relevant literature.

Conclusion: The importance of early computed tomography (< 3 d), anatomy of the perimesencephalic and neighboring cisterns, and adequate four-vessel angiography are discussed. Treatment strategies, including the avoidance of repeated angiographic studies and surgical exploration, are presented.
