Cerebral amyloid angiopathy (CAA) has been proven to be the most common pathological change in cerebral small vessel disease except arteriosclerosis. In recent years, with the discovery of imaging technology and new imaging markers, the diagnostic rate of CAA has greatly improved. CAA plays an important role in non-hypertensive cerebral hemorrhage and cognitive decline. This review comprehensively describes the etiology, epidemiology, pathophysiological mechanisms, clinical features, imaging manifestations, imaging markers, diagnostic criteria, and treatment of CAA to facilitate its diagnosis and treatment and reduce mortality.

脑淀粉样血管病：一种不可否认的小血管疾病。

脑淀粉样血管病（CAA）已被证明是脑小血管疾病中除动脉硬化外最常见的病理改变。近年来，随着影像技术和新影像标志物的发现，CAA的诊断率大大提高。 CAA在非高血压性脑出血和认知能力下降中发挥重要作用。本文全面介绍CAA的病因、流行病学、病理生理机制、临床特征、影像学表现、影像学标志物、诊断标准和治疗，以利于其诊断和治疗，降低死亡率。
