Paracentral strip infarcts of the middle cerebral artery: Borderzone ischaemia or cortical artery occlusion?

Abstract

Background and Purpose: We have noted the presence of small strip-like infarcts involving the cortex within the interdivisional territory of the middle cerebral artery (MCA) and sometimes extending to the periventricular region.
