Acute Cerebral Infarction Related to Stenosis of Accessory Middle Cerebral Artery / 대한뇌졸중학회지

ABSTRACT

The accessory middle cerebral artery (MCA) is an anomalous vessel which arises from the anterior cerebral artery (ACA) and runs through the Sylvian fissure along with the normal MCA. Here we present a case of acute cerebral infarction in a patient with stenosis of the accessory MCA. The accessory MCA, which originated from the proximal A1 segment of the ACA, had severe focal stenosis in its proximal part and the ischemic lesions were in the frontal subcortical white matter. This case illustrates the anomalous vessel and its territory, the atheromatous vascular change, and the related ischemic insults.
