Findings supporting CAA-RI include patchy or confluent T2 hyperintensity of subcortical white matter lesions, which are mostly asymmetric, in addition to the presence of multiple, strictly lobar CMBs and cSS on T2 or SWI, which is also a typical finding in CAA [Figure 1]. (2016) Radiology. PMC Cerebral amyloid angiopathy associated with inflammation: report of 3 cases and systematic. [2,1719] In addition, some researchers still believe that CAA-RI/ICAA and ABRA are two different disease entities. Inflammatory cerebral amyloid angiopathy.

Rajczewska-Oleszkiewicz C, Cyganek A, Stadnik A, Dziewulska D. Cerebral amyloid angiopathy-related inflammation - a case report presenting diagnostic difficulties. In contrast to CAA, which is currently without effective treatment, most studies have shown that empirical high-dose corticosteroids with or without additional immunosuppressive therapy can mitigate symptoms and imaging abnormalities and can improve the prognosis of CAA-RI. Early diagnosis and timely treatment may improve prognosis. [15] In fact, these two types sometimes do coexist. [17] In this review, cognitive decline was the most common clinical manifestation, accounting for 48%, followed by seizures (32%), headache (32%), encephalopathy (27%), presenting as confusion or disturbance of consciousness, weakness (16%), and aphasia (14%). 40.

Pathogenetical subtypes of recurrent intracerebral hemorrhage: designations by SMASH-U classification system. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. The aim of future research should focus on specific pathogenic mechanisms and inflammatory pathways to determine which types of CAA patients are prone to developing inflammation, whether other genes or alleles besides APOE 4 are also risk factors, how they play a role in the mechanism, and so on. [50,51] In these extreme cases, brain biopsy seems to be the only choice. [22] Nevertheless, in our experience, this is not typical and may not be meaningful in clinical practice. Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis. Cerebral amyloid angiopathy (CAA) is a type of cerebrovascular disorder characterized by the accumulation of amyloid within the leptomeninges and small/medium-sized cerebral blood vessels. Unable to load your collection due to an error, Unable to load your delegates due to an error. These symptoms may also include seizures and cognitive decline. 2020; 16:30-42. doi: 10.1038/s41582-019-0281-2 Google Scholar; 35. The same criteria as the possible category with the exception that the MRI white matter hyperintensities are also asymmetric, and that asymmetry is not due to past intracerebral hemorrhage. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. Moosavi B, Torres C, Jansen G. Case 232: amyloid--related angiitis. Dear Sirs, Cerebral amyloid angiopathy (CAA) causes intracerebral haemorrhages and is associated with cognitive impairment and Alzheimer's disease.

Anti-amyloid beta autoantibodies in cerebral amyloid angiopathy-related inflammation: implications for amyloid-modifying therapies. Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. However, some studies have questioned the idea. Cerebral amyloid angiopathy and Alzheimer disease - one peptide, two pathways. Chung KK, Anderson NE, Hutchinson D, Synek B, Barber PA. Cerebral amyloid angiopathy related inflammation: three case reports and a. Update of hot topics in neuralogic diseases. Vessel wall enhancement, however, is not specific for inflammation and may be seen with noninflammatory amyloid angiopathy 12. 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. Anti-A autoantibodies in the CSF of a patient with CAA-related inflammation: a case report. Epub 2022 Aug 5. (B) Strictly lobar CMBs. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been reported. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. There is currently no long-term follow-up cohort to establish prognosis, and differences in prognoses associated with different therapies for different subtypes are worth investigating. It is worth noting that CAA-RI is a diagnosis by exclusion. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. Chu S, Xu F, Su Y, Chen H, Cheng X. Cerebral Amyloid Angiopathy (CAA)-Related Inflammation: Comparison of Inflammatory CAA and Amyloid--Related Angiitis. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y. Epub 2015 Jul 2.

Scolding NJ, Joseph F, Kirby PA, Mazanti I, Gray F, Mikol J, et al. -, Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. Sakai K, Ueda M, Fukushima W, Tamaoka A, Shoji M, Ando Y, et al. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. In addition to clinical symptoms and image findings, detection of genotypes, CSF biomarkers, such as anti-A autoantibodies, and amyloid PET may also provide diagnostic evidence and serve as tools for evaluating treatment efficacy. Cerebral amyloid angiopathy-related inflammation (CAAri) is characterized by vasogenic edema and multiple cortical/subcortical microbleeds, sharing several aspects with the recently defined amyloidrelated imaging abnormalities (ARIA) reported in Alzheimer's disease (AD) passive immunization therapies. If the brain biopsy result is negative, but the patient meets the clinicoradiological diagnostic criteria, the course of action remains uncertain. 42. Inflammatory cerebral amyloid angiopathyis 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. About 60% of patients died or were severely disabled after immunotherapy, and there was no statistically significant difference in terms of prognosis between the two pathological types. 17. Corovic A, Kelly S, Markus HS. Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation. [62,63] Thus, it is very important to recognize the clinical and radiological properties of CAA-RI and bear some differential diagnoses in mind; those substantial differential diagnoses should be ruled out before CAA-RI was diagnosed. Wolters Kluwer Health FOIA Highlight selected keywords in the article text. A study has shown that more patients with ABRA (33.0%) require a combination of steroids and immunosuppressants than do patients with ICAA (12.8%), to achieve similar outcomes. The use of glucocorticoids and immunosuppressants improves prognosis. Inflammatory cerebral amyloid angiopathy is a largely reversible inflammatory vasculopathy that develops in an acute or subacute fashion in reaction to amyloid protein deposition in the central nervous system blood vessels. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. Cerebral amyloid angiopathy with related inflammation (CAA-RI) is an uncommon inflammatory subtype of CAA, with a variety of presentations that can mimic other focal and diffuse neurological disorders. [4] With the development of imaging technology, more clinical silent patients are identified by the classic imaging abnormalities, including multiple strictly lobar cerebral microbleeds (CMBs), cortical superficial siderosis (cSS) or cortical subarachnoid hemorrhage, and cortical atrophy.[3]. Thus, it needs to be established whether excessive immune suppression would have an adverse effect on the long-term prognosis of patients. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. There are still many questions related to CAA-RI that require investigation. CAA causes bleeding into the brain ( hemorrhagic stroke) and dementia. 1. The results of lumbar puncture revealed that more than 80% of patients had increased CSF protein, 44% had pleocytosis,[17] and generally no oligoclonal bands were detected. [2527] ARIA is also divided into two categories: ARIA-E, which manifests as focal or confluent vasogenic edema on fluid-attenuated inversion recovery (FLAIR) sequence images, and ARIA-H, characterized by CMBs or cSS on T2-weighted gradient-echo/susceptibility-weighted imaging (SWI) sequence scans, corresponding to the image hallmarks of CAA-RI. 2019 Sep-Oct;42:36-40. doi: 10.1016/j.carpath.2019.05.004. In an elderly patient with multiple white matter lesions and the appropriate clinical presentation, MR images depicting microhemorrhages may be the key to diagnosing cerebral amyloid angiopathy-related inflammation; finding the apolipoprotein E 4-4 genotype may strongly support the diagnosis. 2022 Jul;9(7):1102-1103. doi: 10.1002/acn3.51596. DiFrancesco JC, Touat M, Caulo M, Gallucci M, Garcin B, Levy R, et al. Although tumors, neurosarcoidosis, Hashimoto encephalopathy, ADEM, or PACNS are unlikely to be aggravated by empirical usage of corticosteroids, the treatment may obscure the diagnosis of those diseases. The case of an 85-year-old female with acute right hemiparesis with status epilepticus. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. In the remainder, which accounts for 60% of all affected individuals, even with treatment severe disability or death are encountered 2. Sakai K, Hayashi S, Sanpei K, Yamada M, Takahashi H. Multiple cerebral infarcts with a few vasculitic lesions in the chronic stage of cerebral amyloid angiopathy-related inflammation. Rarer, inflammatory forms (CAAi) are characterized by the presence of . Morris, M. Grundman. Auriel et al[13] updated the criteria in 2016, defined the WMH pattern specific for distinguishing between probable and possible CAA-RI, and proposed cSS as a marker of hemorrhage. However, given the segmental distribution of the lesions, they may be missed by the biopsy, which will lead to a missed diagnosis. Wermer MJH, Greenberg SM. 23. Careers. In another case, the patient had clinical and imaging characteristics of CAA-RI, but because of bicytopenia and an increase in CRP and lactate dehydrogenase, lymphoma was suspected. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. doi: 10.1097/MD.0000000000003613. official website and that any information you provide is encrypted While changes are typically confined to the subcortical white matter, the involvement of the cortex is also encountered and predisposes to seizures 1,2. Epub 2022 Mar 14. Amyloid PET is also unavailable in most hospitals in China. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. 45. HHS Vulnerability Disclosure, Help There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). Cerebral amyloid angiopathy and cerebral amyloid angiopathy-related inflammation: comparison of hemorrhagic and DWI MRI features. 8600 Rockville Pike Mandal J, Chung SA. Abstract. In humans, cerebral amyloid angiopathy and related vascular dysfunction are suggested to affect small vessels in the cortical areas [30,31]. Cerebral amyloid angiopathy (CAA) is an important cause of cognitive impairment and spontaneous intracerebral hemorrhage in the elderly. 25. Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions. [11] The most commonly used immunosuppressants are cyclophosphamide (33.9%), azathioprine (5.0%), mycophenolate mofetil (5.0%), methotrexate, immunoglobulin, and so on.

Auriel E, Charidimou A, Gurol ME, Ni J, Van Etten ES, Martinez-Ramirez S, et al. The mechanism underlying CAA-RI remains unclear. [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. Please enable it to take advantage of the complete set of features! It is easy for doctors to diagnose CAA-RI when patients were APOE 4/4 homozygotes with typical clinical characteristics and image. Typical images of cerebral amyloid angiopathy-related inflammation. Danve A, Grafe M, Deodhar A. Amyloid beta-related angiitis--a case report and comprehensive. [18] Sakai et al[32] reported a case of CAA-RI at the chronic stage, with persistently elevated proteinase 3-antineutrophil cytoplasmic antibody levels. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an unusual cause of encephalopathy, seizures and focal neurological deficits.1 2 We report three cases of CAA-ri with minimal symptoms but striking and dynamically evolving brain MRI findings. In addition, some researchers found that, compared with non-inflammatory CAA, PACNS, and healthy controls, patients with CAA-RI have relatively low levels of A42 and A40 in the CSF. This site needs JavaScript to work properly. Stroke-Like Episodes Heralding a Reversible Encephalopathy: Microbleeds as the Key to the Diagnosis of Cerebral Amyloid Angiopathy-Related Inflammation-A Case Report and Literature Review. Occasional cases of pathologically-confirmed inflammatory cerebral amyloid angiopathy have been reported with prominent leptomeningeal involvement without the typical white matter or hemorrhagic lesions on imaging 5,6. In one case, heart transplantation was performed because of sarcoid cardiomyopathy, followed by long-term use of immunosuppressants, and CAA-RI occurred during hospitalization after mycobacterial infection. - "Advancing diagnostic criteria for sporadic cerebral amyloid angiopathy: Study protocol for a multicenter MRI-pathology validation of . doi: 10.1097/MD.0000000000003613. Cerebral amyloid--related angiitis without cerebral microbleeds in a patient with subarachnoid hemorrhage. Case of cerebral amyloid angiopathy-related inflammation - is the absence of cerebral microbleeds a good prognostic sign? Kirshner et al[8] reported a CAA-RI patient with pathologically confirmed grade III anaplastic astrocytoma. The presence of symmetric white matter lesions that extend to the immediately subcortical white matter would only meet the criteria for "possible" inflammatory cerebral amyloid angiopathy 4. J Alzheimers Dis. (E) No significant changes with CMBs. Lesions are usually unifocal but multifocal involvement is occasionally present at the time of diagnosis (~30%)1. 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. A is deposited segmentally, but can be found in all those inflammation sites. 8. Disclaimer. Mendona MD, Caetano A, Pinto M, Cruz e Silva V, Viana-Baptista M. J Stroke Cerebrovasc Dis. 61. 46. Blood tests may reveal signs of inflammation. In addition, it has been observed that immune activation in the parenchyma near the affected blood vessels increased significantly and the A load decreased accordingly. 59. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. Many diseases with similar clinical manifestations should be carefully ruled out. 13. This method scores the most advanced degree of CAA present within the specimen. 28. Biopsy obtained from the white matter showed no evidence of inflammation in one case. The .gov means its official. Additionally, although there is considerable overlap, inflammatory cerebral amyloid angiopathy should be distinguished from amyloid-related imaging abnormalities (ARIA)that are seen in the setting of treatment with novel amyloid-lowering therapies such as monoclonal antibodies 13. Amyloidogenic peptides in this condition are nearly always the same ones found in alzheimer disease. However, there are many atypical cases or cases without T2/SWI sequence that were initially misdiagnosed, in whom the diagnosis was later revised. [64] Another patient was first diagnosed with PRES, which was responsive to anti-edema intravenous steroid and antihypertensive therapy. 95 (20): e3613. Cerebral amyloid angiopathy (CAA) is a kind of disease in which amyloid (A) and other amyloid protein deposits in the cerebral cortex and the small blood vessels of the brain, causing . Summary of MRI markers of small vessel disease and CAA to be evaluated in the project, including their definition, ratings scales and important points/modifications in their assessment specifically for clinical use within the Boston criteria v.2.0. 51 (2): 525-32. CAA is defined by histopathologydeposition of -amyloid in the cerebrovasculatureand through the 1980s the disorder was only diagnosed in patients with available brain tissue from hematoma evacuation, biopsy, or most commonly postmortem examination. 62.

J Clin Med. However, the prognosis of most untreated patients is poor. [2] CAA is clinically diverse. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare variant of CAA with autoimmune inflammation. Coulette S, Renard D, Lehmann S, Raposo N, Arquizan C, Charif M, et al. WMHs sometimes extend to the cortex with a mass effect showing hyperintensity in maps of apparent diffusion coefficient suggesting vasogenic edema. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. 3.

A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. 56. [39] One patient with a history of Parkinson's disease (PD) was mistakenly thought to have developed the mental manifestation of PD when he presented with the symptoms of CAA-RI. 4. Cerebral amyloid angiopathy associated with inflammation: a systematic, 18. 31. Cerebral amyloid angiopathy (CAA) is a common small vessel disease characterized by the deposition of amyloid (A) protein mainly in the media and adventitia of small- and medium-sized leptomeningeal and cortical blood vessels. [33] Findings from several systematic reviews have shown that there is no obvious gender difference, but a slight male predominance was observed. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. BMC Neurol. Pathological changes within the cerebral vasculature in Alzheimer's disease: New perspectives. 2018;64(4):1113-1121. doi: 10.3233/JAD-180269. Many cases have reported that patients were misdiagnosed with tumors, and the diagnosis was modified to CAA-RI when the data were retrospectively analyzed or after the biopsy results became available.
