Recurrent cerebral microbleeds with acute stroke symptoms

摘要

Rationale:Cerebral microbleeds are lesions that appear as round low signal intensity areas with a diameter of 2–5 mm on gradient echo T2-weighted sequence magnetic resonance imaging. Cerebral microblees are hemorrhages found in the brain parenchyma and they are caused by the extravasation of the blood. Although more patients with ischemic stroke are found to have cerebral microbleeds, only a few studies have evaluated other neurologic abnormalities outside of cognitive dysfunction due to cerebral microbleeds.
