Abstract

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.

대뇌 아밀로이드 혈관병증 관련 염증은 베타 아밀로이드가 혈관에 침착되어 혈관 주위의 급성 염증성 반응으로 발생하는 뇌병증이다. 이 질환은 주로 고령자에게서 발생하는 드문 질환으로, 급격히 진행하는 치매, 두통, 발작, 국소 신경학적 결손을 동반한 증상으로 나타나며 특징적인 뇌자기공명영상 소견을 보인다. 또한 스테로이드 또는 기타 면역억제요법에 반응하는 가역적인 질병이다. 대뇌 아밀로이드 혈관병증 관련 염증을 처음에는 아급성 경색으로 오진하였다가 추적 관찰 중 뇌 자기공명영상 소견을 분석하면서 대뇌 아밀로이드 혈관병증 관련 염증이 진단되었고, 자연 관해가 이뤄진 대뇌 아밀로이드 혈관병증 관련 염증 증례를 보고한다.
