Silent microbleeds are associated with volume of primary intracerebral hemorrhage

The authors performed a correlative radiologic study on the micro-bleeds and volume of intracerebral hemorrhage in the supratentorial ICH patients. In the patients with lobar or putaminal hemorrhage, the hemorrhage volumes increased more than twofold or threefold in the patients with micro-bleeds. Moreover, the presence of microbleeds was an independent risk factor for large-sized hemorrhage. These data show that microbleeds may be associated with a larger ICH volume.
