Cerebral amyloid angiopathy-related inflammation (CAA-RI) is an encephalopathy caused by inflammation of β-amyloid peptide deposition in cerebrovascular vessels. It is a rare disease that mainly occurs in the elderly and is characterized by rapidly progressive dementia, headache, seizures, and focal neurologic deficits. CAA-RI can demonstrate characteristic brain MRI findings and can be reversed by steroids or other immunosuppressive therapies. Here, we report a case of CAA-RI, which was initially misdiagnosed as a subacute infarction but was diagnosed while reviewing follow-up brain MRI images, and spontaneous remission was achieved.
脑淀粉样血管病相关性炎症（CAA-RI）是一种由脑血管中β淀粉样肽沉积引发炎症所致的脑病。它是一种罕见疾病，主要发生于老年人，其特征为快速进展性痴呆、头痛、癫痫发作和局灶性神经功能缺损。CAA-RI可表现出特征性的脑部MRI表现，并且可通过类固醇或其他免疫抑制疗法得到缓解。在此，我们报告一例CAA-RI病例，该病例最初被误诊为亚急性梗死，但在复查脑部MRI随访图像时得以确诊，并实现了自发缓解。
