The Characteristics of Superficial Siderosis and Convexity Subarachnoid Hemorrhage and Clinical Relevance in Suspected Cerebral Amyloid Angiopathy

摘要

Background and aimsSystematic studies of superficial siderosis(SS) and convexity subarachnoid hemorrhage (cSAH) in patients with suspected cerebral amyloid angiopathy(CAA) without lobar intracerebral hemorrhage(ICH) are lacking. We sought to determine the potential anatomic correlation between SS/cSAH and transient focal neurological episodes (TFNE) and whether SS/SAH is predictor of future cerebral hemorrhagic events in these patients.
