Due to these atypical symptoms, advanced imaging is very meaningful for clinical diagnosis. Course of cerebral amyloid angiopathy-related inflammation. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). [6,66] In addition, these two conditions may be present concurrently. Cerebral amyloid angiopathy-related inflammation (CAA-ri), also referred to as inflammatory cerebral amyloid angiopathy and A-related angiitis, is a distinct subset of cerebral amyloid angiopathy (CAA) characterized by an autoimmune reaction to cerebrovascular -amyloid deposits. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. Salvarani C, Brown RD Jr, Calamia KT, Christianson TJ, Huston J 3rd, Meschia JF, et al. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion.

Renard D, Wacongne A, Ayrignac X, Charif M, Fourcade G, Azakri S, et al. Historically, only ICAA was initially considered to be the only inflammatory form of CAA,[9] while ABRA was thought to represent coexisting primary angiitis of the central nervous system (PACNS) and CAA. [28] Antibody levels decrease after corticosteroid therapy,[2,42] indicating that anti-A autoantibody may be used as a biomarker for both diagnosis and monitoring the effect of treatment. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731.

The diagnostic criteria for "probable" inflammatory cerebral amyloid angiopathy require white matter hyperintensities on T2-FLAIRthat are asymmetric and extend to the immediately subcortical white matter 4. 38. Phrases such as CAA associated with inflammation, CAA-RI, ICAA, and ABRA are used interchangeably. Inflammatory cerebral amyloid angiopathy is an uncommon cerebral amyloid deposition disease, closely related to the far more common non-inflammatory cerebral amyloid angiopathy , and can present as areas of vasogenic edema. [5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. The site is secure. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. It would be more difficult to identify patients who also have a history of tumors. After treatment with corticoids, (D) WMH faded significantly. MRI is the modality of choice in assessing these patients as it is able to visualize the characteristic peripheral microhemorrhages of cerebral amyloid angiopathy. 8. Since there is no A deposition in the blood vessels supplying the spinal cord, symptoms of myelopathy have not been reported in ICAA and ABRA; thus, PACNS is a more likely diagnosis when symptoms involving the spinal cord occur. Brain MRI 9 months later showed multiple discrete regions . Epub 2022 Mar 14. In addition, the treatment of infection and other comorbidities should be considered in such cases.

[14] Based on the criteria of leptomeningeal enhancement, the sensitivity and specificity of recognizing CAA-RI from CAA patients are reported to be 70.4% and 92.6%, respectively. Semin Arthritis Rheum. However, given the segmental distribution of the lesions, they may be missed by the biopsy, which will lead to a missed diagnosis. The .gov means its official. 3. 20. Thus, in this review, we present the main pathological, clinical, neuroimaging, therapeutic, and prognostic features and the diagnostic criteria of CAA-RI to shed some light on its clinical practice, and then discuss issues that remain unresolved. 31. After several recurrences, WMH and CMBs progressed and long-term follow-up led to a diagnosis of CAA-RI. CAA-RI shares pathologic characteristics of CAA, which is A deposition in the cortical or leptomeningeal vessels, with positive Congo red staining. 22. Typical images of cerebral amyloid angiopathy-related inflammation. 48. [2,46,68] The most common abnormality found in PACNS is the presence of proximal or distal stenosis on MRA or conventional digital subtraction angiography; this is not commonly seen in CAA-RI. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Kirshner HS, Bradshaw M. The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI).
