Simplified computed tomography is useful for ruling in cerebral amyloid angiopathy in lobar intracerebral hemorrhage

Takeaway

• The simplified Edinburgh computed tomography (CT)-based criteria appeared clinically useful in predicting cerebral amyloid angiopathy (CAA) in patients who have lobar intracerebral hemorrhage (ICH).

Why this matters

• Accurate diagnostic characterization of ICH is essential for appropriate acute and long-term management but evaluation of bleeding etiologies, such as CAA, remains challenging in people with lobar ICH.

• CAA is associated with >2-fold risk of recurrent ICH and requires long-term management with antithrombotic medication, compared with other etiologies that require acute treatment. Early and precise diagnosis of CAA is therefore essential for treatment decision-making.
