Sulcal Hyperintensity as an Early Imaging Finding in Cerebral Amyloid Angiopathy–Related Inflammation

Abstract

Regions of sulcal hyperintensity, sometimes with associated gyral swelling, can be an early imaging finding in CAA-ri. These neuroimaging markers could potentially improve the accuracy of existing diagnostic criteria for CAA-ri to allow earlier diagnosis and treatment without biopsy in patients with atypical presentations.
