Typical images of cerebral amyloid angiopathy-related inflammation. However, the prognosis of most untreated patients is poor. Nouh A, Borys E, Gierut AK, Biller J. Amyloid-Beta related angiitis of the central nervous system: case report and topic. Carmona-Iragui M, Fernndez-Arcos A, Alcolea D, Piazza F, Morenas-Rodriguez E, Antn-Aguirre S, et al. 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. Case of cerebral amyloid angiopathy-related inflammation - is the absence of cerebral microbleeds a good prognostic sign? Morris, M. Grundman.

However, the average patient is a little younger than in non-inflammatory cerebral amyloid angiopathy and older than those with non-amyloid primary cerebral angiitis 2. PMC Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. If only routine sequences are performed, it is easy to mistake WMH as the only image manifestation and consequently delay diagnosis and treatment. 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. 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. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory effect. Saliou V, Ben Salem D, Ognard J, Guellec D, Marcorelles P, Rouhart F, et al. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity. [18] It can be concluded that these pathologically similar diseases constitute a spectrum from CAA to PACNS [Table 1]. Epub 2014 Feb 11. Ann Neurol 2013; 73:449. Kotsenas AL, Morris JM, Wald JT, Parisi JE, Campeau NG. (C) No enhancement was seen. sharing sensitive information, make sure youre on a federal Medicine (Baltimore). Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. The former represents the inflammatory form of CAA, while the latter is an independent disease or a subtype of PACNS associated with CAA. 16. 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. 36. Miller-Thomas MM, Sipe AL, Benzinger TL et-al. [17] While another systematic review showed that the functional outcome of most patients was not ideal. Due to these atypical symptoms, advanced imaging is very meaningful for clinical diagnosis. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. National Library of Medicine Epub 2022 Mar 14. 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. Reid and Maloney first described CAA with vascular inflammation in a patient with AD in 1974, and subsequent cases were reported. 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. Teaching neuro: cerebral amyloid angiopathy-related inflammation presenting with isolated leptomeningitis. Unauthorized use of these marks is strictly prohibited. [57] A reduction of CMBs was found in one case after immunotherapy, but it cannot be ruled out that the natural course of CAA-RI may include a spontaneous reduction in CMBs. Cerebral amyloid angiopathy (CAA) is a condition in which proteins called amyloid build up on the walls of the arteries in the brain. Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. [50,51] In these extreme cases, brain biopsy seems to be the only choice. 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. However, anticoagulation was later suspended due to cerebral hemorrhage, and the patient was finally diagnosed with CAA-RI. 39. [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. 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. It is easy for doctors to diagnose CAA-RI when patients were APOE 4/4 homozygotes with typical clinical characteristics and image. Course of cerebral amyloid angiopathy-related inflammation. - "Advancing diagnostic criteria for sporadic cerebral amyloid angiopathy: Study protocol for a multicenter MRI-pathology validation of Boston criteria v2.0" Thus, it needs to be established whether excessive immune suppression would have an adverse effect on the long-term prognosis of patients. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. Perivascular and vascular inflammatory patterns without granulomas accounted for 22.5% of cases. Primary central nervous system vasculitis: comparison of patients with and without cerebral amyloid angiopathy. 2014 Aug;44(1):86-92. doi: 10.1016/j.semarthrit.2014.02.001. to maintaining your privacy and will not share your personal information without [18] Although the APOE 2 allele is considered a protective factor against AD, it clearly increases the risk of vascular disease.

Wolters Kluwer Health [69] A systematic review of both pathological subtypes revealed that, during an average follow-up period of 24 months, 55% of patients eventually end up being asymptomatic or with mild disability. It would be more difficult to identify patients who also have a history of tumors. Please enable it to take advantage of the complete set of features! These patients typically present with subacute mental status changes, headaches, and seizures, typically at a slightly younger age than those presenting with . Amyloid can be confirmed when the Congo red-stained section shows green birefringence under polarized light. [14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. 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. 1. In autopsy series, the estimated prevalence of CAA is high (20-40 % in nondemented subjects; 50-60 % in dementia) [1]. This article reviews the pathology and pathogenesis, clinical and imaging manifestations, diagnostic criteria, treatment, and prognosis of CAA-RI, and highlights unsolved problems in the existing research. Cerebral amyloid angiopathy is one of the leading causes of intracerebral hemorrhage and a significant contributor to age-related cognitive decline. (2016) Medicine. Pathogenetical subtypes of recurrent intracerebral hemorrhage: designations by SMASH-U classification system. Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. (C) No enhancement was seen. 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. Accessibility Immunosuppressants can be administered in cases showing no response to glucocorticoids or for preventing recurrence. 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. Porter M, Newey CR, Toth G. Teaching NeuroImages: treatment-resistant rapidly progressive amyloid -related angiitis. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. (A) Confluent WMH. Chin Med J 2021;134:646654. 42. Nakaya M, Hashimoto H, Usui G, Sawada K, Shirouzu I, Oshima A, et al. It may also present with cognitive impairments, incidental . [12,14,18] The erythrocyte sedimentation rate was increased in 37.5% of patients, while C-reactive protein (CRP) was elevated in 60%. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. For these reasons, this article does not attempt to distinguish between subtypes and treats the terms interchangably.

A definite diagnosis requires pathologic demonstration (such as biopsy or autopsy). Cerebral Amyloid Angiopathy and Cerebral Amyloid Angiopathy-Related Inflammation: Comparison of Hemorrhagic and DWI MRI Features. The clinical presentation is usually acute or subacute 1,2, but may be chronic4. Validation of Clinicoradiological Criteria for the Diagnosis of Cerebral Amyloid Angiopathy-Related Inflammation. This highlights the significance of the T2/SWI sequences in differentiation. 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. Piazza F, Greenberg SM, Savoiardo M, Gardinetti M, Chiapparini L, Raicher I, et al. Martucci M, Sarria S, Toledo M et-al. In patients who respond to treatment, imaging follow-up demonstrates regression of the aforementioned inflammatory findings. Angiography does not reveal evidence of vasculitis involving the large- or medium-sized vessels 6. 10. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. Typical images of cerebral amyloid angiopathy-related inflammation. sharing sensitive information, make sure youre on a federal Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. 10: 984. 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. DiFrancesco JC, Touat M, Caulo M, Gallucci M, Garcin B, Levy R, et al. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. Table 3. 23. The incidence of multiple lobar CMBs, as well as the total number of CMBs is significantly higher in CAA-RI patients. This pathological distinction is not reliably predicted on imaging 2. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. 64. Hao Q, Tsankova NM, Shoirah H, Kellner CP, Nael K. Vessel Wall MRI Enhancement in Noninflammatory Cerebral Amyloid Angiopathy. Cerebral amyloid angiopathy-related inflammation: a case report presenting with a rare variant in SORL1 gene. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. 2. Anti-amyloid autoantibodies in cerebral amyloid angiopathy-related inflammation: implications for amyloid-modifying therapies. Sengoku R, Matsushima S, Murakami Y, Fukuda T, Tokumaru AM, Hashimoto M, et al. 60. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. There have been few epidemiological studies on CAA-RI. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. After treatment with corticoids, (D) WMH faded significantly. Renard D, Tatu L, Collombier L, Wacongne A, Ayrignac X, Charif M, Boukriche Y, Chiper L, Fourcade G, Azakri S, Gaillard N, Mercier E, Lehmann S, Thouvenot E. J Alzheimers Dis. However, biopsy is invasive; consequently, some criteria for the diagnosis of CAA-RI have been based on clinical and radiological data. 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. The .gov means its official. Brain Pathol. [22,31] In fact, both ICAA and ABRA can present with or without granulomatous inflammation. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. 12. Once the diagnosis is made, glucocorticoids or even immunosuppressants should be adopted in order to improve the prognosis. doi: 10.1097/WCO.0000000000000510. [17] And the youngest case with pathologic evidence ever reported was 42 years old.[34]. (B) Strictly lobar, MeSH [28] CAA-RI is thought to be a spontaneous ARIA, while ARIA is considered to be iatrogenic CAA-RI. Careers. [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. Cerebral amyloid angiopathy-related inflammation with posterior reversible encephalopathy syndrome-like presentation: a case report. and transmitted securely. After treatment with corticoids, (D) WMH faded significantly. WMH and vasogenic edema accompanied by a mass effect make brain tumors a highly suspected differentiation. This also reflects the importance of the SWI sequence. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). A 62-year-old man presented with a moderately severe non-radiating frontal headache. Ichimata S, Hata Y, Yoshida K, Nishida N. Autopsy of a multiple lobar hemorrhage case with amyloid--related angiitis. 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. Bookshelf Hence, in such cases, close follow-up should be performed. However, clinicoradiological diagnostic criteria have been proposed for cerebral amyloid angiopathy related inflammation 4. at least one of these clinical features not directly attributable to an acute intracerebral hemorrhage: MRI with white matter hyperintensities (unifocal or multifocal, corticosubcortical or deep) that extend to the immediately subcortical white matter, at least one of these corticosubcortical hemorrhagic lesions: cerebral macrobleed, cerebral microbleed, or cortical superficial siderosis, absence of neoplastic, infectious, or other cause. 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. [14] Previous studies have revealed that, compared with multiple sclerosis and healthy people, anti-A autoantibodies in the CSF of CAA-RI patients increased during the acute phase, which is consistent with what was observed in ARIA, supporting the aforementioned hypothesis of an A-induced immune response. 61. 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. 10. Cerebrospinal fluid, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation. 7. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. There are still many questions related to CAA-RI that require investigation. Blood tests may reveal signs of inflammation. Amyloid--related angiitis: a report of 2 cases with unusual presentations. 2016YFC1300500-505). Moreover, amyloid deposits start in the cortical areas and spread to the hippocampal areas at a later stage [32,33].

Prodromal Alzheimer's disease presenting as cerebral amyloid angiopathy-related inflammation with spontaneous amyloid-related imaging abnormalities and high cerebrospinal fluid anti-A autoantibodies. Salvarani C, Morris JM, Giannini C, Brown RD, Christianson T, Hunder GG. 63. This disorder typically responds to steroids but addition of other immune suppressants may be needed in some cases to control the disease. By definition, CAA is characterized by vessel wall amyloid deposits. Inflammatory Cerebral Amyloid Angiopathy, Amyloid-Related Angiitis, and Primary Angiitis of the Central Nervous System. In addition, when starting the treatment, infection needs to be ruled out first, to avoid pervasion due to corticosteroid therapy. Reid AH, Maloney AF. Beta-APP42 may activate mononuclear phagocytes in the brain and elicit inflammatory responses. 32. Liang JW, Zhang W, Sarlin J, Boniece I. National Library of Medicine [10] The carriage rate in non-inflammatory CAA patients was only 5.1%,[10] and it is rarely seen in healthy people or stroke patients. The diagnostic criteria for both probable and possible inflammatory cerebral amyloid angiopathy require at least one corticosubcortical hemorrhagic lesion 4, which is best demonstrated as signal loss on T2*-weighted sequences (susceptibility-weightedor gradient echo): cerebral macrobleed (intraparenchymal hematoma), cerebral microbleed (cerebral microhemorrhage). 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. Conclusive diagnosis of CAA-RI requires histopathological confirmation, but it is invasive and has certain risks. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Moreover, the efficacy of treatment was evaluated by observational studies; consequently, more clinical trials and even randomized clinical trials are required. Clinical manifestations of cerebral amyloid angiopathy-related inflammation. FOIA Coulette S, Renard D, Lehmann S, Raposo N, Arquizan C, Charif M, et al. Although CAA-RI is relatively rare at present, it may become more common in future with the improvement of diagnostic techniques. [14] The dosage used is based on individual selection. Probable Cerebral Amyloid Angiopathy-Related Inflammation Associated With Sitravatinib: A Case Report. Sugihara S, Ogawa A, Nakazato Y, Yamaguchi H. Cerebral beta amyloid deposition in patients with malignant neoplasms: its prevalence with aging and effects of radiation therapy on vascular amyloid. 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. Anti-amyloid beta autoantibodies in cerebral amyloid angiopathy-related inflammation: implications for amyloid-modifying therapies. 65. In humans, cerebral amyloid angiopathy and related vascular dysfunction are suggested to affect small vessels in the cortical areas [30,31]. It is conceivable that posterior reversible encephalopathy syndrome (PRES) is a very important differential diagnosis. Tumors including primary central nervous system lymphomas and metastases should be taken into consideration when making a diagnosis in such patients. Vonsattel grading for CAA severity on neuropathology samples. doi: 10.1111/bpa.13061. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. Typical images of cerebral amyloid angiopathy-related inflammation. Cerebral Amyloid Angiopathy (CAA) Associated with Inflammation (Inflammatory CAA) Background: Cerebral amyloid angiopathy (CAA) is characterized by deposition of amyloid-beta in the media and adventitia of cortical and leptomeningeal arteries. Unable to load your collection due to an error, Unable to load your delegates due to an error. [48,49], Gadolinium enhancement of parenchyma or leptomeninges may or may not be present [Figure 1],[43,50] although the proportion of enhancing cases in CAA-RI is significantly higher than that in non-inflammatory CAA cases. Other synonyms used for this entity include cerebral amyloid inflammatory vasculopathy,amyloid angiopathy and granulomatous angiitis of the central nervous system,cerebral amyloid angiitis, primary angiitis of the central nervous system associated with cerebral amyloid angiopathy, and cerebral amyloid angiopathy associated with giant cell arteritis9.

This article reviews the pathology and pathogenesis, clinical and imaging manifestations, diagnostic criteria, treatment, and prognosis of CAA-RI, and highlights unsolved problems in the existing research. 48. A 77-year-old female experienced light-headedness during walking and mild ataxic gait without any other objective neuropsychological deficits. [19] Spontaneous remission has been reported in some cases,[7,71] the fundamentals of which are not yet known. Epub 2022 Aug 5. Susceptibility-weighted imaging is more reliable than T2-weighted gradient-recalled echo MRI for detecting microbleeds. 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. Terminology [70] The clinical features of relapse are widely distributed, among which the decline of cognitive function and encephalopathy are the most common symptoms. These symptoms may also include seizures and cognitive decline. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. The APOE 4 allele is currently the only confirmed risk factor for CAA-RI. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Leptomeningeal and parenchymal vessels should be scored separately.
