Core Tip

Core Tip: Relevant cases of spontaneous subarachnoid hemorrhage (SAH) recurrence, the underlying mechanisms and possible etiology were reviewed. Perimesencephalic nonaneurysmal SAH (PNSAH) recurrence should arouse vigilance; however, the definite source of idiopathic SAH in this case report deserves further attention. Furthermore, patients should be advised regarding the potential recurrence of PNSAH.
