Background: A pretruncal subarachnoid hemorrhage has been accepted as a "benign" entity. Here we present two patients with delayed cerebral infarction following pretruncal subarachnoid hemorrhage.
Methods: Case report.
Results: Two patients with possible delayed cerebral infarction after pretruncal subarachnoid hemorrhage were identified. Both patients developed basilar artery vasospasm within 2 weeks of their bleeding events. Although they remained clinically asymptomatic, the location and the timing of infarction implicated the observed focal arterial vasospasm.
Conclusions: Clinicians should bear in mind the possibility of arterial vasospasm and ensuing cerebral infarction in patients with pretruncal subarachnoid hemorrhage.

Distinguishing the aneurysmal from nonaneurysmal subarachnoid hemorrhage (SAH) may be difficult as acute bleeding in the subarachnoid space is a common denominator. It is believed that toxic effects of breakdown products of acute bleed, including hemoglobin, contribute to the morbidity and mortality of this condition; and that early drainage will potentially reduce them. This series focuses on our local experience with the application of external cerebrospinal fluid (CSF) drainage in the management of a series of cases confirmed to be nonaneurysmal SAH and its effects on the outcome.

Background: Spontaneous subarachnoid haemorrhage (SAH) is a significant cause of stroke and associated with high morbidity and mortality. One substantial complication of SAH is cerebral vasospasm (CV) and delayed cerebral ischemia (DCI). This study aimed to define the clinical profile in patients with SAH, CV and DCI secondary to spontaneous SAH (aneurysmal and pretruncal non-aneurysmal).

Background: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSH) is characterized by a typical pattern of localized pretruncal hemorrhage on head computed tomography. PNSH is usually associated with a benign clinical course and a lower incidence of complications. The etiology is unknown, but many explanations have been proposed, including venous injury or rupture followed by thrombosis of a ruptured microaneurysm.

Intradural spinal arteriovenous fistulas (sAVF) are spinal vascular lesions that usually manifest due to myelopathy or local symptoms caused by venous congestion and ischemia. In addition, perimedullary arteriovenous fistulas (PMAVF) in particular may rupture and cause subarachnoid or intramedullary hemorrhage along with relevant symptoms. Subarachnoid hemorrhage (SAH) can propagate into cranial space with clinically dominant symptoms and signs of typical aneurysmal intracranial SAH.
