37. Growing numbers of patients have been reported with vascular inflammation associated with advanced cerebral amyloid angiopathy (59; 150). 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. After treatment with corticoids, (D) WMH faded significantly. [6,66] In addition, these two conditions may be present concurrently. Diagnostic procedures in this setting include blood tests, neuroimaging, CSF analysis, and brain biopsy when necessary to make a diagnosis of CAA-RI, as well as to exclude other conditions. http://creativecommons.org/licenses/by-nc-nd/4.0. Cerebral amyloid angiopathy is unrelated to generalized amyloidosis. 8600 Rockville Pike Clipboard, Search History, and several other advanced features are temporarily unavailable. The diagnostic efficiency for possible CAA-RI is low, with a specificity of only 68%. Immunosuppressive therapy is effective both during initial presentation and in relapses. Our clinical experience also supports this conclusion [Figure 1]. [11] The gold standard test for diagnosis is autopsy or brain biopsy. In addition, the treatment of infection and other comorbidities should be considered in such cases. Thus, it needs to be established whether excessive immune suppression would have an adverse effect on the long-term prognosis of patients. [11] This phenomenon may be explained by the fact that the blood vessel wall in cases of ICAA is less destroyed than that in cases of ABRA. This method scores the most advanced degree of CAA present within the specimen. [14], Angio-destructive changes, such as fibrinoid necrosis can also be found in some of the vessel walls in patients affected by ABRA.

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. Cenina AR, De Leon J, Tay KY, Wong CF, Kandiah N. Cerebral amyloid angiopathy-related inflammation presenting with rapidly progressive dementia, responsive to IVIg. (C) No enhancement was seen. Magnetic resonance angiography (MRA) or cerebral angiography is unremarkable in CAA-RI, due to the small caliber of the involved blood vessels, which prevents the lesion from being captured. Cancelloni V, Rufa A, Battisti C, De Stefano N, Mastrocinque E, Garosi G, Venezia D, Chiarotti I, Cerase A. Neurol Sci. Third, A was engulfed by macrophages expressing MHC class II antigens near CD4+ T cells, suggesting that A plays a pathogenic role in inducing inflammation in ABRA. Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. Brain MRI lesions; Cerebral amyloid angiopathy; Cerebral small vessel disease; Inflammation; Review. Hao Q, Tsankova NM, Shoirah H, Kellner CP, Nael K. Vessel Wall MRI Enhancement in Noninflammatory Cerebral Amyloid Angiopathy. Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation. 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). 60. Epub 2022 May 18. Thomas Tropea, Prasad Shirvalkar, Krithiga Sekar, Kyung-Wha Kim, Apostolos Tsiouris, Ehud Lavi, Alan Segal. However, anticoagulation was later suspended due to cerebral hemorrhage, and the patient was finally diagnosed with CAA-RI. 12. Terminology In the vast majority of cases (90%), microhemorrhages are present 1,2. [54] Therefore, the presence of the APOE 4/4 genotype may be meaningful for the diagnosis of CAA-RI. PMC 8600 Rockville Pike Unauthorized use of these marks is strictly prohibited. Cheng AL, Batool S, McCreary CR, Lauzon ML, Frayne R, Goyal M, et al. A Report of 2 Cases. If there is no response to corticosteroid therapy within 3 weeks, biopsy should be reconsidered to confirm the diagnosis. In addition, when starting the treatment, infection needs to be ruled out first, to avoid pervasion due to corticosteroid therapy. Epub 2015 Jul 2. [22,31] In fact, both ICAA and ABRA can present with or without granulomatous inflammation. 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.

There is currently no study giving recommendations on the choice of medication, dosage, and the time span of treatment. After several recurrences, WMH and CMBs progressed and long-term follow-up led to a diagnosis of CAA-RI. Cerebral amyloid angiopathy. 41 (3): 446-448. Many diseases with similar clinical manifestations should be carefully ruled out. (2016) Neurology. HHS Vulnerability Disclosure, Help Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis. (A) Confluent WMH. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been reported. A case of cerebral amyloid angiopathy-related inflammation with the rare apolipoprotein epsilon2/epsilon2 genotype. [5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. Discussion This report of neurologic autoimmunity in a patient receiving sitravatinib opens new lines of inquiry into the pathophysiology of CAA-ri. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Dear Sirs, Cerebral amyloid angiopathy (CAA) causes intracerebral haemorrhages and is associated with cognitive impairment and Alzheimer's disease. Mendona MD, Caetano A, Pinto M, Cruz e Silva V, Viana-Baptista M. 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. Cases of an isolated leptomeningeal process on imaging are more commonly categorized as amyloid related angiitis, within the limitations of variable terminology noted above 6. [3] CAA related lobar ICH has been identified as the second most common form of spontaneous ICH following hypertensive angiopathy. Savoiardo M, Erbetta A, Storchi G, Girotti F. Case 159: cerebral amyloid angiopathy-related inflammation. An alternative transcript of the Alzheimer's disease risk gene SORL1 encodes a truncated receptor. Some cases presented with involuntary movement,[35,36] while others had systemic diseases,[14] cerebral hernia caused by severe edema,[37] uveitis,[21] multiple malignancies,[14,15,38] extracranial vasculitis, or vascular dysplasia at baseline. 29.

MRA and vessel wall imaging may show medium-sized arteries involved with multifocal stenoses with wall thickening/enhancement 11. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. The incidence of multiple lobar CMBs, as well as the total number of CMBs is significantly higher in CAA-RI patients. 39. CT and MRI demonstrate an area of vasogenic edema involving the subcortical white matter 1. Second, vasculitis and the vascular areas affected by A co-localize. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein.

Brain Pathol. In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. [55,56] Thus, 2 carriers may also be predisposed to CAA-RI. However, many authors interchange the terms "cerebral amyloid angiopathy-related inflammation" and "inflammatory cerebral amyloid angiopathy," either encompassing of amyloid -related angiitis 8 or in distinction to it 3.

[18] It can be concluded that these pathologically similar diseases constitute a spectrum from CAA to PACNS [Table 1]. (2013) American Journal of Neuroradiology. Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. However, the average patient is a little younger than in non-inflammatory . Clinical history of progressive cognitive decline over a few weeks and asymmetrically grouped cerebral microbleeds with focal corticosubcortical FLAIR hyperintensity, untypical for stroke and without restricted diffusion, we suspected cerebral amyloid angiopathy related inflammation (CAA-RI). [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Cerebral amyloid angiopathy is a common small vessel disease in the elderly involving vascular amyloid- deposition. Cerebral amyloid angiopathy (CAA) is a cerebrovascular disorder caused by the accumulation of cerebral amyloid- (A) in the tunica media and adventitia of leptomeningeal and cortical vessels of the brain. Ronsin S, Deiana G, Geraldo AF, Durand-Dubief F, Thomas-Maisonneuve L, Formaglio M, et al. The clinical manifestations of PACNS can also mimic the pattern of CAA-RI. [2023] In recent years, it has gradually come to be accepted that these two pathological types are essentially similar.

Some of these diseases can be ruled out by T2 MRI or SWI. Recurrence of cerebral amyloid angiopathy-related inflammation: a report of two cases from the iCAbeta international network. [33] Findings from several systematic reviews have shown that there is no obvious gender difference, but a slight male predominance was observed. The major clinical manifestations of CAA-RI are subacute mental disorders and behavioral or cognitive changes, headaches, seizures, and focal neurological deficits, which are different from CAA. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Cerebrospinal fluid, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation.

Acute ischemic lesions in cerebral amyloid angiopathy-related inflammation. Introduction [17] Multiple lobar CMBs were found on SWI or T2 images in most patients, but some cases of pathologically confirmed CAA-RI were without CMBs on MRI. [14] The dosage used is based on individual selection. It is worth noting that CAA-RI is a diagnosis by exclusion. -, Reid AH, Maloney AF. 31. Sporadic cerebral amyloid angiopathy (CAA) is a common age-related small vessel disease of the brain, characterized by progressive deposition of amyloid- peptide in the walls of small- to medium-sized arteries, arterioles, and capillaries of the cerebral cortex and overlying leptomeninges [ 1 ]. Inflammatory Disorders of the Central Nervous System Vessels: Narrative Review. (C) No enhancement was seen. Diagnosis, treatment, and follow-up of patients with cerebral amyloid angiopathy-related inflammation. Blood tests may reveal signs of inflammation. An increase in inflammatory biomarkers has been observed in CAA-RI patients in different studies. Rajczewska-Oleszkiewicz C, Cyganek A, Stadnik A, Dziewulska D. Cerebral amyloid angiopathy-related inflammation - a case report presenting diagnostic difficulties. For these reasons, this article does not attempt to distinguish between subtypes and treats the terms interchangably.

In the remainder, which accounts for 60% of all affected individuals, even with treatment severe disability or death are encountered 2. and transmitted securely. [61] Despite this, negative brain biopsy findings are insufficient to exclude the diagnosis of CAA-RI, because of the segmental distribution of pathological changes. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral hemorrhage. doi: 10.1016/j.jstrokecerebrovasdis.2015.04.042. 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 . 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. A nationwide survey demonstrated that its prevalence is about 0.13 per 100,000 population in Japan. Cerebral amyloid angiopathy-related inflammation. 33. [18] The clinical and radiological manifestations may be initially relieved after glucocorticoid therapy, but can relapse after withdrawal of steroids or during dose decrease. It may present with symptomatic acute lobar intracerebral hemorrhage (ICH), chronic progressive cognitive decline, transient focal neurological episodes, and subacute cognitive disorder or behavioral changes caused by CAA-related inflammation (CAA-RI).

The term "inflammatory cerebral amyloid angiopathy" can be used as an umbrella term encompassing two subtypes:cerebral amyloid angiopathy-related inflammation and amyloid -related angiitis2,6. CD4(+) T cells predominate in cerebrospinal fluid and leptomeningeal and parenchymal infiltrates in cerebral amyloid beta-related angiitis. Beta-amyloid peptides bind to lipoproteins and apolipoproteins E and J in the CSF and to HDL particles in plasma, inhibiting metal-catalyzed oxidation of lipoproteins. [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. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y.

[17] Steroid therapy is also effective during recurrence, but increased microbleeds may be detected with T2/SWI sequences in that case. [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. Risk factor SORL1: from genetic association to functional validation in Alzheimer's disease. Abeta-related angiitis: primary angiitis of the central nervous system associated with cerebral amyloid angiopathy. Neuroradiology. Disclaimer. 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. Biopsy obtained from the white matter showed no evidence of inflammation in one case. Sakai K, Ueda M, Fukushima W, Tamaoka A, Shoji M, Ando Y, et al. 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. 8. Imaging findings of cerebral amyloid angiopathy, Abeta-related angiitis (ABRA), and cerebral amyloid angiopathy-related inflammation: a single-institution 25-year experience.
