Abstract
|
|
|
|
A 44-year-old woman presented with acute confusion, apparently due to a clinically silent subarachnoid hemorrhage followed by vasospasm, which in turn led to an ischemic stroke. During the initial evaluation, an acute ischemic stroke in the left middle cerebral artery territory was observed. Magnetic resonance imaging revealed a late subacute hemorrhage in the left basal cistern. Digital subtraction angiography indicated the presence of a small saccular aneurysm that had recently ruptured, as well as vasospasm in the left circle of Willis. Balloon angioplasty and balloon-assisted coil embolization were performed for the vasospasm and saccular aneurysm, respectively. This case demonstrates that clinically silent subarachnoid hemorrhages resulting in ipsilateral vasospasm and infarction can occur as complications of a ruptured aneurysm.
