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.
