Highlight
Diffusion-weighted imaging (DWI)-positive lesions are common in acute intracerebral hemorrhage (ICH) patients and independently associate with markers of cerebral small vessel disease (cSVD) and poor 6-month functional outcomes. The anatomical distribution of these lesions differs between cerebral amyloid angiopathy (CAA) and non-CAA subtypes. Larger hematoma volume and severe white matter hyperintensities (WMH) correlate with the presence of DWI-positive lesions.
