Bilateral anterior cerebral artery thrombosis - a mimicker of basilar artery thrombosis: a case report

Abstract

We present a rare case of bilateral anterior cerebral artery (ACA) territory infarction with akinetic mutism, quadriparesis and frontal lobe release signs along with limbic dysfunction mimicking a basilar artery thrombosis. The etiology was thrombosis of the anterior communicating artery with propagation or embolism of the thrombus to both A2 segments of the anterior cerebral artery and restricted or absent blood flow in the branches arising from the A2 and A3 segments causing extensive infarction. We also aim to review the anatomy of the ACA to understand localization of lesions.
