2016;51(2):525-32. doi: 10.3233/JAD-151036. [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. [2] CAA is clinically diverse. [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. [72] It is worth noting that this case involved a patient who had been using immunosuppressive agents. (2015) Stroke. Chu S, Xu F, Su Y, Chen H, Cheng X. Cerebral amyloid angiopathy (CAA)-related inflammation: comparison of inflammatory CAA and amyloid-beta-related angiitis. Kirshner HS, Bradshaw M. The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). Although CAA-RI is relatively rare at present, it may become more common in future with the improvement of diagnostic techniques. -, Wermer MJH, Greenberg SM. CAA is an important cause of lobar intracerebral hemorrhage in older adults [ 1,2 ]. 2. [65] Therefore, these two diseases are sometimes difficult to distinguish, and it may be necessary to observe changes during follow-up to obtain the correct diagnosis. Cerebral amyloid--related angiitis without cerebral microbleeds in a patient with subarachnoid hemorrhage. Objective. Cerebral amyloid angiopathy. 72. Probatory corticoid treatment resolved FLAIR changes . 37. Kotsenas AL, Morris JM, Wald JT, Parisi JE, Campeau NG. Reduction of microbleeds by immunosuppression in a patient with A-related vascular inflammation. 5. Cerebral amyloid angiopathy is unrelated to generalized amyloidosis. Careers. Recurrence of cerebral amyloid angiopathy-related inflammation: a report of two cases from the iCAbeta international network. (2016) Neurology. [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. However, due to the relatively few 2 alleles or genotypes detected in cases, it is difficult to determine the role of 2 in CAA-RI in small sample studies. (from kumar: robbins and cotran: pathologic basis of disease, 7th ed., 2005) ICD-10-CM I68.0 is grouped within Diagnostic Related Group (s) (MS-DRG v40.0): 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. 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. National Library of Medicine Accessibility 1. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. 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. 64. 21. Reid and Maloney first described CAA with vascular inflammation in a patient with AD in 1974, and subsequent cases were reported. In humans, cerebral amyloid angiopathy and related vascular dysfunction are suggested to affect small vessels in the cortical areas [30,31]. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. Cerebral amyloid angiopathy (CAA) is an important cause of cognitive impairment and spontaneous intracerebral hemorrhage in the elderly. Case of cerebral amyloid angiopathy-related inflammation - is the absence of cerebral microbleeds a good prognostic sign? [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. Please try after some time. Cerebral amyloid angiopathy and cerebral amyloid angiopathy-related inflammation: comparison of hemorrhagic and DWI MRI features. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory effect. 46. Federal government websites often end in .gov or .mil. In fact, in a subgroup of patients, spontaneous remission is encountered 1. [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. 41. doi: 10.5853/jos.2015.17.1.17. The growing clinical spectrum of cerebral amyloid angiopathy. [12,13] Because immunosuppressive therapy is effective for the disease, timely diagnosis and early commencement of therapy are very important. Biomedicines. Tumefactive cerebral amyloid angiopathy mimicking CNS neoplasm. Kimura A, Sakurai T, Yoshikura N, et al. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. 2022 Dec 3;22(1):449. doi: 10.1186/s12883-022-02979-6.

Chinese Medical Journal134(6):646-654, March 20, 2021. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity. Acta Neuropathol 1974; 27:131137. Martucci M, Sarria S, Toledo M, Coscojuela P, Vert C, Siurana S, et al. In patients who respond to treatment, imaging follow-up demonstrates regression of the aforementioned inflammatory findings. 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). [12,14,18] The erythrocyte sedimentation rate was increased in 37.5% of patients, while C-reactive protein (CRP) was elevated in 60%. [16,17] However, the terms used to describe this disease are confusing. 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. The APOE 4 allele is currently the only confirmed risk factor for CAA-RI. Curr Neurol Neurosci Rep. 2015 Aug;15(8):54. doi: 10.1007/s11910-015-0572-y. (2016) Radiology. SWI or T2: which MRI sequence to use in the detection of cerebral microbleeds? The use of glucocorticoids and immunosuppressants improves prognosis. 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. 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. Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. 1. 10: 984. A report of 2 cases. The case of an 85-year-old female with acute right hemiparesis with status epilepticus. 7. If only routine sequences are performed, it is easy to mistake WMH as the only image manifestation and consequently delay diagnosis and treatment. Cerebral amyloid angiopathy-related inflammation: a case report presenting with a rare variant in SORL1 gene. Epub 2014 Feb 11. One case was initially suspected of PRES or cerebral venous sinus thrombosis and was treated with anticoagulant and steroid. Another option is to follow the patient up closely. http://creativecommons.org/licenses/by-nc-nd/4.0. 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. An official website of the United States government. [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. Radiographics. By definition, CAA is characterized by vessel wall amyloid deposits. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. Inflammatory Cerebral Amyloid Angiopathy, Amyloid-Related Angiitis, and Primary Angiitis of the Central Nervous System. For these reasons, this article does not attempt to distinguish between subtypes and treats the terms interchangably. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Corticosteroid therapy in a patient with cerebral amyloid angiopathy-related inflammation. Terminology 12. Cerebral amyloid--related angiitis without cerebral microbleeds in a patient with subarachnoid hemorrhage. Nakaya M, Hashimoto H, Usui G, Sawada K, Shirouzu I, Oshima A, et al. 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. [40] Whether the etiology of these comorbidities, such as autoimmunity, or their treatment, such as radiation therapy,[41] are related to CAA-RI requires further study. Curr Opin Neurol 2018; 31:2835. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. Leptomeningeal contrast enhancement is seen in approximately half of patients 1,2. 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. PMC Many diseases with similar clinical manifestations should be carefully ruled out. Revesz T, Holton JL, Lashley T, Plant G, Frangione B, Rostagno A, Ghiso J. Genetics and molecular pathogenesis of sporadic and hereditary cerebral amyloid angiopathies. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. The gold standard for diagnosis is autopsy or brain biopsy. 2014 Aug;44(1):86-92. doi: 10.1016/j.semarthrit.2014.02.001.

Boncoraglio GB, Piazza F, Savoiardo M, Farina L, DiFrancesco JC, Prioni S, et al. 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. The .gov means its official. Rajczewska-Oleszkiewicz C, Cyganek A, Stadnik A, Dziewulska D. Cerebral amyloid angiopathy-related inflammation - a case report presenting diagnostic difficulties. -. Hence, in such cases, close follow-up should be performed. [13] Nevertheless, these criteria are still imperfect, as samples included in the validation trial was small. It may also present with cognitive impairments, incidental . Melzer N, Harder A, Gross CC, Wolfer J, Stummer W, Niederstadt T, et al. (2016) Medicine. [18] It can be concluded that these pathologically similar diseases constitute a spectrum from CAA to PACNS [Table 1]. 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. The .gov means its official. Disclaimer. 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. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. 38. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. [18] Sakai et al[32] reported a case of CAA-RI at the chronic stage, with persistently elevated proteinase 3-antineutrophil cytoplasmic antibody levels. Copyright 2021 Elsevier B.V. All rights reserved. (2013) American Journal of Neuroradiology. Anti-A autoantibodies in the CSF of a patient with CAA-related inflammation: a case report. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare variant of CAA with autoimmune inflammation. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. The clinical manifestations of PACNS can also mimic the pattern of CAA-RI. [46] Two-thirds of ABRA patients and only 31.3% of ICAA patients showed contrast enhancement on MRI. [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 and Alzheimer disease - one peptide, two pathways. 11. 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. Bookshelf FOIA [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. Inflammatory cerebral amyloid angiopathy. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al. It would be more difficult to identify patients who also have a history of tumors. Unable to load your collection due to an error, Unable to load your delegates due to an error.

[14] The recurrence probability of CAA-RI has differed across studies. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. However, the prognosis of most untreated patients is poor. Sperling R, Salloway S, Brooks DJ, Tampieri D, Barakos J, Fox NC, et al. The diagnostic criteria for possible or probable inflammatory cerebral amyloid angiopathy require age 40 years 4. It is generally recommended that brain biopsy should be performed from an area with abnormal radiologic manifestations, preferably at a lesion in the cortex or leptomeninges. This case was reminiscent of ANCA-associated vasculitis, although the relationship between proteinase 3-antineutrophil cytoplasmic antibody and the pathogenesis of CAA-RI remains unclear. 60. [3] CAA related lobar ICH has been identified as the second most common form of spontaneous ICH following hypertensive angiopathy. 19. Department of Neurology, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing 100730, China. Unable to load your collection due to an error, Unable to load your delegates due to an error. Similar clinical processes and radiological changes of CAA-RI appear in amyloid-related imaging abnormalities (ARIA), initially during the clinical trial of bapineuzumab, the monoclonal antibody for AD, and later in that of other amyloid modification therapies. However, some studies have questioned the idea. modify the keyword list to augment your search. A 62-year-old man presented with a moderately severe non-radiating frontal headache. BMC Neurol. Nouh A, Borys E, Gierut AK, Biller J. Amyloid-Beta related angiitis of the central nervous system: case report and topic. 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). Teaching neuro: cerebral amyloid angiopathy-related inflammation presenting with isolated leptomeningitis. Still others refer to only cerebral amyloid angiopathy-related inflammation alone 1,4,5,10or amyloid -related angiitis alone 7without mention of the other. Growing numbers of patients have been reported with vascular inflammation associated with advanced cerebral amyloid angiopathy (59; 150). In addition, there is a need to determine more biomarkers by which to modify the diagnostic criteria and further improve diagnostic efficiency. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. 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. 69. 1 Introduction of the imaging-based Boston criteria for diagnosis of CAA in the 1990s 2, 3 Mendona MD, Caetano A, Pinto M, Cruz e Silva V, Viana-Baptista M. J Stroke Cerebrovasc Dis. Early diagnosis and timely treatment may improve prognosis. 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. Risk factor SORL1: from genetic association to functional validation in Alzheimer's disease. 8600 Rockville Pike 2022 Nov;32(6):e13061. 54. [17] While another systematic review showed that the functional outcome of most patients was not ideal. This site needs JavaScript to work properly. An individual with cerebral amyloid angiopathy-related inflammation who displayed involuntary movements. Amyloid can be confirmed when the Congo red-stained section shows green birefringence under polarized light. [67] For such patients, a clinicoradiological diagnosis only may result in missing a coexisting tumor, and thus the pros and cons of biopsy should be weighed carefully. There are still many questions related to CAA-RI that require investigation. Cerebral amyloid angiopathy associated with inflammation: report of 3 cases and systematic. 58. Thus, it needs to be established whether excessive immune suppression would have an adverse effect on the long-term prognosis of patients. 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. [5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. 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. Savoiardo M, Erbetta A, Storchi G, Girotti F. Case 159: cerebral amyloid angiopathy-related inflammation. The work cannot be changed in any way or used commercially without permission from the journal. 34 (10): 1958. A clinico-radiological study of cerebral amyloid angiopathy-related inflammation. Hemorrhage and white matter injury seen at imaging reflect vascular damage caused by the accumulation of A in vessel walls. Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. It is worth noting that CAA-RI is a diagnosis by exclusion. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been 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.
