Distinctive distribution of cerebral microbleeds
Distinctive distribution of cerebral microbleeds
(A-C) CMBs on T2*-weighted gradient echo MRI sequences suggestive of deep penetrating (hypertensive) vasculopathy. CMBs predominate in bilateral thalami (A), brainstem (B), and dentate nucleus of cerebellum (C).
(D-F) CMBs on T2*-weighted gradient echo MRI sequences suggestive of cerebral amyloid angiopathy. CMBs predominate in cerebral hemispheres (D, E). Associated findings include lobar hemorrhage (D; arrow and thick arrow) and superficial siderosis (F; circles).
CMB: cerebral microbleeds; MRI: magnetic resonance imaging.
