- Abstract
- Hyperintense vessels are frequently observed on fluid-attenuated inversion recovery imaging in acute ischemic stroke
patients. Some investigators suggest that a hyperintense vessel sign in patients with middle cerebral arterial occlusion
results
from collateral blood flow originating in neighboring arterial territories, especially via pial collaterals. We report
two cases of acute proximal middle cerebral arterial infarction that exhibited hyperintense vessels signs on
fluid-attenuated inversion recovery imaging accompanying pial collaterals as confirmed by cerebral angiography. Key Words: Fluid-attenuated inversion recovery, Cerebral infarction, Collateral circulation
