[22] Nevertheless, in our experience, this is not typical and may not be meaningful in clinical practice. 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. 8. Miller-Thomas MM, Sipe AL, Benzinger TL et-al. doi: 10.1097/CM9.0000000000001427, This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited. Andersen OM, Rudolph IM, Willnow TE. Cerebral amyloid angiopathy (CAA) is presented with progressive deposition of amyloid proteins within the cortical and leptomeningeal arteries, which is a common pathology in the elder [1, 2].In recent years, studies show that coexisting inflammations found in CAA patients, such as vasculitis or perivasculitis, have been recognized as CAA-related inflammation (CAA-ri) []. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. The https:// ensures that you are connecting to the [Cerebral Amyloid Angiopathy-Related Inflammation/Vasculitis]. Neurol Clin Pract. 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. [18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. (E) No significant changes with CMBs. Due to the potentially reversible WMH in ICAA,[43] when clinical manifestations are present and findings on conventional MRI sequences are suggestive, it must be distinguished from PRES, which also has the characteristic of bilateral confluent T2 WMH, but is often associated with hypertension or other conditions. [2023] In recent years, it has gradually come to be accepted that these two pathological types are essentially similar. Reduction of microbleeds by immunosuppression in a patient with A-related vascular inflammation. 72. Keywords: Vonsattel grading for CAA severity on neuropathology samples. SWI or T2: which MRI sequence to use in the detection of cerebral microbleeds? The gold standard for diagnosis is autopsy or brain biopsy. [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. 16. 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 asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. Aghetti A, Sne D, Polivka M, Shor N, Lechtman S, Chabriat H, Jouvent E, Guey S. Cerebral Amyloid Angiopathy Related Inflammation With Prominent Meningeal Involvement. Before Validation of clinicoradiological criteria for the diagnosis of cerebral amyloid angiopathy-related inflammation. [15] In fact, these two types sometimes do coexist. A report of 2 cases. Clinical Presentation: Patients typically present with seizures, headache, and strokelike episodes, along with an acute or subacute decline in cognitive status. This disorder typically responds to steroids but addition of other immune suppressants may be needed in some cases to control the disease. Rapid progressive dementia, headache, seizures, or focal neurological deficits, with patchy or confluent hyperintensity on T2 or fluid-attenuated inversion recovery sequences and evidence of strictly lobar microbleeds or cortical superficial siderosis on susceptibility-weighted imaging imply CAA-RI. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. These symptoms may also include seizures and cognitive decline. CAA is an important cause of lobar intracerebral hemorrhage in older adults [ 1,2 ]. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. Hainline C, Rucker JC, Zagzag D, Golfinos JG, Lui YW, Liechty B, et al. Disclaimer. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. 64. A definite diagnosis requires pathologic demonstration (such as biopsy or autopsy). [72] It is worth noting that this case involved a patient who had been using immunosuppressive agents.

Bethesda, MD 20894, Web Policies Salloway SP, Sperling R, Fox NC, Sabbagh MN, Honig LS, Porsteinsson AP, et al. For more information, please refer to our Privacy Policy. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral haemorrhage. There are also cases of CAA-RI patients reported with genotype APOE 2/2 and APOE 2/3. 37. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion. 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. Cerebrospinal fluid, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation. 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 . Still others refer to only cerebral amyloid angiopathy-related inflammation alone 1,4,5,10or amyloid -related angiitis alone 7without mention of the other. 3. At present, the main recommendation is that high-dose glucocorticoids should be used. Amyloid angiopathy is a condition in which amyloid peptides are deposited in vessel walls in the brain and meninges, with a pattern of "microbleeds" visible on MRI gradient echo imaging and a tendency for large, lobar intracerebral hemorrhages. However, the average patient is a little younger than in non-inflammatory . [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. The most recent systematic review included 213 pathologically confirmed cases of CAA-RI. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. Epub 2022 Aug 5. Theodorou A, Palaiodimou L, Safouris A, Kargiotis O, Psychogios K, Kotsali-Peteinelli V, Foska A, Zouvelou V, Tzavellas E, Tzanetakos D, Zompola C, Tzartos JS, Voumvourakis K, Paraskevas GP, Tsivgoulis G. J Clin Med. 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. This also reflects the importance of the SWI sequence. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. -, Reid AH, Maloney AF. 6. Vessel wall enhancement, however, is not specific for inflammation and may be seen with noninflammatory amyloid angiopathy 12. HHS Vulnerability Disclosure, Help doi: 10.1161/strokeaha.114.005598. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. Acute ischemic lesions in cerebral amyloid angiopathy-related inflammation. 8600 Rockville Pike In addition, when starting the treatment, infection needs to be ruled out first, to avoid pervasion due to corticosteroid therapy. Cerebral amyloid angiopathy is one of the leading causes of intracerebral hemorrhage and a significant contributor to age-related cognitive decline. Porter M, Newey CR, Toth G. Teaching NeuroImages: treatment-resistant rapidly progressive amyloid -related angiitis. Objective. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is characterized by sub-acute confusion, progressive cognitive decline, seizure or headaches; reversible focal subcortical and/or cortical T2 hyperintensities on magnetic resonance imaging (MRI); and neuropathological evidence of cerebral amyloid angiopathy (CAA) and associated vascular or perivascular inflammation [1-3]. However, some studies have questioned the idea. Moreover, the efficacy of treatment was evaluated by observational studies; consequently, more clinical trials and even randomized clinical trials are required. The gold standard for diagnosis is autopsy or brain biopsy. 256 (1): 323-7. Ronsin S, Deiana G, Geraldo AF, Durand-Dubief F, Thomas-Maisonneuve L, Formaglio M, et al. In the vast majority of cases (90%), microhemorrhages are present 1,2. Amyloidogenic peptides in this condition are nearly always the same ones found in alzheimer disease. Key Diagnostic Features: [28] CAA-RI is thought to be a spontaneous ARIA, while ARIA is considered to be iatrogenic CAA-RI. 2022 Dec 3;22(1):449. doi: 10.1186/s12883-022-02979-6. Mendona MD, Caetano A, Pinto M, Cruz e Silva V, Viana-Baptista M. J Stroke Cerebrovasc Dis. In humans, cerebral amyloid angiopathy and related vascular dysfunction are suggested to affect small vessels in the cortical areas [30,31]. Moreover, amyloid deposits start in the cortical areas and spread to the hippocampal areas at a later stage [32,33]. Unable to load your collection due to an error, Unable to load your delegates due to an error. Leptomeningeal enhancement may be a unique imaging manifestation in some cases with confirmed CAA-RI. [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. 13. [11] The most commonly used immunosuppressants are cyclophosphamide (33.9%), azathioprine (5.0%), mycophenolate mofetil (5.0%), methotrexate, immunoglobulin, and so on. Szpak GM, Lewandowska E, Sliwiska A, Stpie T, Tarka S, Mendel T, et al. This site needs JavaScript to work properly. [19,29,30] Usually, B lymphocytes are fewer compared to T cells. 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. doi: 10.1007/bf00687163.

Cerebral amyloid angiopathy-related inflammation presenting with rapidly progressive dementia, responsive to IVIg. 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. Phrases such as CAA associated with inflammation, CAA-RI, ICAA, and ABRA are used interchangeably. Savoiardo M, Erbetta A, Storchi G, Girotti F. Case 159: cerebral amyloid angiopathy-related inflammation. [18] However, these results should be carefully considered because the high proportion of granulomatous inflammation may be due to the higher biopsy rate in those cases showing more serious clinical and imaging manifestations and a tendency of malignant diseases.[22]. 10. 73 (2): 197-202. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been reported. FOIA This pathological distinction is not reliably predicted on imaging 2. Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation. Kang P, Bucelli RC, Ferguson CJ, Corbo JC, Kim AH, Day GS. Kimura A, Sakurai T, Yoshikura N, et al.

Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Mandal J, Chung SA. Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. It is not clear why only a small proportion of patients with CAA develop inflammation against A. Dear Sirs, Cerebral amyloid angiopathy (CAA) causes intracerebral haemorrhages and is associated with cognitive impairment and Alzheimer's disease. These cases emphasize that CAA-RI is a diagnosis by exclusion. Cerebral amyloid angiopathy and cerebral amyloid angiopathy-related inflammation: comparison of hemorrhagic and DWI MRI features. Nouh A, Borys E, Gierut AK, Biller J. Amyloid-Beta related angiitis of the central nervous system: case report and topic. may email you for journal alerts and information, but is committed This study was supported by a grant from the National Key Research and Development Program of China (No. 59. (A) Confluent WMH. An official website of the United States government. [14] The dosage used is based on individual selection. [12,13] Because immunosuppressive therapy is effective for the disease, timely diagnosis and early commencement of therapy are very important. The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. Immunosuppressants can be administered in cases showing no response to glucocorticoids or for preventing recurrence. Ann Clin Transl Neurol. However, many patients present with atypical symptoms other than those mentioned above, which may easily lead to an incorrect diagnosis. 28. Renard D, Wacongne A, Ayrignac X, Charif M, Fourcade G, Azakri S, et al. [28] This strongly suggests that an immune response to A is responsible for CAA-RI. These patients typically present with subacute mental status changes, headaches, and seizures, typically at a slightly younger age than those presenting with . [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. J. Barakos, R.

A spectrum from CAA to PACNS: pathological differences between CAA, ICAA, ABRA, and PACNS. 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. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. In fact, in a subgroup of patients, spontaneous remission is encountered 1. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Due to these atypical symptoms, advanced imaging is very meaningful for clinical diagnosis. 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. [20] The incidence of ARIA gradually increased with an increase in the therapeutic antibody dose. 40. MRI is the modality of choice in assessing these patients as it is able to visualize the characteristic peripheral microhemorrhages of cerebral amyloid angiopathy. 36. 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. The growing clinical spectrum of cerebral amyloid angiopathy. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). The distribution of CMBs does not follow the regional pattern of occipital dominance in non-inflammatory CAA. [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. PMC Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. Second, vasculitis and the vascular areas affected by A co-localize. 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. doi: 10.1111/bpa.13061. Zhu X, Schrader JM, Irizarry BA, Smith SO, Van Nostrand WE. The white matter hyperintensity represents vasogenic edema, which may show localized mass effect. The diagnosis of inflammatory cerebral amyloid angiopathy on clinicoradiologic grounds requires the exclusion of other causes: amyloid-related imaging abnormalities (ARIA)seen in patients treated with amyloid lowering therapies 13, infection, such as progressive multifocal leukoencephalopathy (PML)or meningoencephalitis of various causes, vascular pathologies, such as primary CNS vasculitisor posterior reversible encephalopathy syndrome (PRES), Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. After treatment with corticoids, (D) WMH faded significantly. However, antibody titer determination kits are currently not commercially available and are still worth developing. Federal government websites often end in .gov or .mil. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral hemorrhage. 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. Cerebral amyloid--related angiitis without cerebral microbleeds in a patient with subarachnoid hemorrhage. DiFrancesco JC, Longoni M, Piazza F. Anti-Abeta autoantibodies in amyloid related imaging abnormalities (ARIA): candidate biomarker for immunotherapy in Alzheimer's disease and cerebral amyloid angiopathy. The rare forms of inflammatory angiopathy attributed to A, A-related angiitis . There are two major types of CAA: one is hereditary CAA, which is associated with Down syndrome or mutations in the A protein precursor (APP) gene or presenilin gene,[1] and the other one is age-related sporadic CAA. Bookshelf A engulfed in macrophages can be observed at times. 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. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require at least one of the following clinical features that are not directly attributable to an acute intracerebral hemorrhage4: Some patients also present with hallucinations 2. Lesions are usually unifocal but multifocal involvement is occasionally present at the time of diagnosis (~30%)1. 35. If the brain biopsy result is negative, but the patient meets the clinicoradiological diagnostic criteria, the course of action remains uncertain. 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. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. [14], Angio-destructive changes, such as fibrinoid necrosis can also be found in some of the vessel walls in patients affected by ABRA. 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. Traschtz A, Tzaridis T, Penner AH, Kuchelmeister K, Urbach H, Hattingen E, et al. Early diagnosis and timely treatment may improve prognosis. [18] Although the APOE 2 allele is considered a protective factor against AD, it clearly increases the risk of vascular disease. Accessibility [46,47] A possible explanation for this finding is that, once an immune response to vascular amyloid protein is generated, it affects multiple regions of brain via the spread of antibodies. Epub 2022 Mar 14. 41 (3): 446-448. 61. 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.
