Which clinical or imaging features of cerebral amyloid angiopathy aid in predicting future risk of intracerebral hemorrhage?

Hemorrhagic imaging features of cerebral amyloid angiopathy can help understand the future risk of intracerebral hemorrhage (ICH). Observational studies have found that patients with cortical microbleeds without lobar hemorrhage have an ~5% risk of future ICH. In those with prior lobar ICH, this ris...

From the literature and my own experience, I think that there are several factors predicting the risk of future hemorrhage. These include: number of microbleeds, any larger bleed on MRI, superficial siderosis, MRI finding of edema and hemorrhages (called CAA-ri, but almost identical to ARIA seen wit...
