Practical Insights
-
- Causes up to 1/5 of primary intracranial hemorrhage in patients >60 years.
- Boston criteria are used for diagnosis without biopsy using presence of multiple asymmetric lobar microhemorrhages, cortical superficial siderosis, and lobar ICH.
- Other markers are multiple dilated perivascular spaces and white matter T2 hyperintensities (70%).
- May show sulcal or leptomeningeal enhancement or focal nonhemorrhagic mass (amyloidoma) extending to the ventricular wall in younger patients.
