Figure 3. Regions of interest. Background:Monoclonal antibody targeting amyloid for removal from the brain appears to unmask cerebral amyloid angiopathy (CAA). This may result in Amyloid Related Imaging Abnormalities (ARIA). ARIA-E is defined as edema, best seen on flair MRI. ARIA-H is defined as hemorrhages best seen on GRE. Both appear related to same increases in vascular permeability. ARIAE occured in 10% of subjects treated with bapineuzumab, and half of these also developed ARIA-H, all MH’s, with correlation in both time and space. Methods:We report a case of serial MRI’s tracking ARIAwith a 7.5 year follow up MRI, the longest reported follow up thus far reported. Results:At 7.5 years, the patient had
