Summary

Cerebral microbleed (CMB) refers to small, round dark-signal lesions detected by T2\*-weighted or gradient-echo (GRE) magnetic resonance imaging (MRI) ..CMBs were introduced to stroke physicians in the late 1990s and early 2000s after development of MRI techniques sensitive to paramagnetic effects The clinical significance of CMBs has been actively investigated, especially in the stroke field and more recently in studies on cognitive impairment, vascular dementia and later developement of cerebral hge ..Histological investigation has shown that CMBs are tiny foci containing hemosiderin-laden macrophages and abnormal microvessels . Clinical cases with frank symptoms caused by CMBs are uncommon, Because CMBs are manifestations of focal extravascular leakage of blood components, however, investigators have suggested that accumulation of CMBs reflects a bleeding-prone status in individuals with an elevated risk of cerebral hemorrhage. Clinical studies have found strong associations between CMBs and chronic hypertension and low cholesterol levels and between the proximity and volume of CMBs and those of subsequent intracerebral hemorrhage (ICH) . studies have found that CMBs are linked to subsequent hemorrhagic stroke in stroke survivors,and suggested that CMBs are related to antithrombotic-related hemorrhage.
