Ischemic Lesions and PACNS Insights

This chapter explores the differences in ischemic lesions between primary angiitis of the central nervous system (PACNS) and cerebral amyloid angiopathy (CAA), noting the challenges in diagnosis through conventional imaging. It emphasizes the significance of biopsy and the identification of specific imaging markers, such as white matter hyperintensities, while calling for improved biomarkers for better diagnostic accuracy.
