10. [14] In addition to A deposition, CAA-RI also demonstrates pronounced perivascular or transmural inflammatory infiltration. 52. The mechanism underlying CAA-RI remains unclear. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. Amyloid can be confirmed when the Congo red-stained section shows green birefringence under polarized light. 2. Lesions are usually unifocal but multifocal involvement is occasionally present at the time of diagnosis (~30%)1. This study was supported by a grant from the National Key Research and Development Program of China (No. Case of cerebral amyloid angiopathy-related inflammation - is the absence of cerebral microbleeds a good prognostic sign? Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. 1. The patient met the criteria for probable cerebral amyloid angiopathy-related inflammation (CAA-ri) and responded favorably to high-dose methylprednisolone. Kimura A, Sakurai T, Yoshikura N, et al. Clipboard, Search History, and several other advanced features are temporarily unavailable. Child ND, Braksick SA, Flanagan EP, Keegan BM, Giannini C, Kantarci OH. J Stroke 2015; 17:1730. 56. It is easy for doctors to diagnose CAA-RI when patients were APOE 4/4 homozygotes with typical clinical characteristics and image. 8. Leptomeningeal contrast enhancement is seen in approximately half of patients 1,2. Thus, other differential diagnoses should be carefully ruled out. BMC Neurol. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. 64. Clinical manifestations of cerebral amyloid angiopathy-related inflammation. Piazza F, Greenberg SM, Savoiardo M, Gardinetti M, Chiapparini L, Raicher I, et al. 38. Discussion This report of neurologic autoimmunity in a patient receiving sitravatinib opens new lines of inquiry into the pathophysiology of CAA-ri. 29. Introduction [58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI. Immune activation in amyloid--related angiitis correlates with decreased parenchymal amyloid- plaque load. Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions. Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. 2021 May;73(5):489-495. doi: 10.11477/mf.1416201790. Federal government websites often end in .gov or .mil. 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. J Alzheimers Dis. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). Since the treatment does not obviously harm the tumor, the response of the lesion to the given treatment can be observed to figure out whether it deteriorates as time goes by. In addition, the treatment of infection and other comorbidities should be considered in such cases. 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. 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. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. A spectrum from CAA to PACNS: pathological differences between CAA, ICAA, ABRA, and PACNS. Saliou V, Ben Salem D, Ognard J, Guellec D, Marcorelles P, Rouhart F, et al. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. Epub 2022 Aug 5. 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. Mandal J, Chung SA. Key Diagnostic Features: Once the diagnosis is made, glucocorticoids or even immunosuppressants should be adopted in order to improve the prognosis. [57]SORL1 encodes a 250-kDa protein called sorting protein-related receptor with A-type repeats (SorLA), which reduces the production and deposition of A peptides by regulating the processing of APP. These symptoms may also include seizures and cognitive decline. The white matter hyperintensity represents vasogenic edema, which may show localized mass effect. [14] However, findings from another study have suggested that non-specific vascular changes in ABRA may be observed when medium-sized arteries are involved. Bethesda, MD 20894, Web Policies [22] Moreover, ischemic stroke is more common in PACNS than in CAA-RI,[24] and there have been only a few cases of patients with CAA-RI presenting with ischemic stroke. WMH and vasogenic edema accompanied by a mass effect make brain tumors a highly suspected differentiation. 35. Update of hot topics in neuralogic diseases. [32] In a systematic review, of the 142 cases with available data, 27.5% presented with both perivascular inflammation and vasculitis with granuloma formation, which is the most common pathological pattern. 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. 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. There have been few epidemiological studies on CAA-RI. 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. These cases emphasize that CAA-RI is a diagnosis by exclusion. [6,66] In addition, these two conditions may be present concurrently. (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): Perivascular and vascular inflammatory patterns without granulomas accounted for 22.5% of cases. 13. Chu S, Xu F, Su Y, Chen H, Cheng X. Cerebral Amyloid Angiopathy (CAA)-Related Inflammation: Comparison of Inflammatory CAA and Amyloid--Related Angiitis. That is, 50% of all cases showed overlap between ICAA and ABRA patterns. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. This is in most cases a non-inflammatory age-related condition that is associated with cerebral hemorrhage, infarcts, leukoencephalopathy and dementia. There is currently no study giving recommendations on the choice of medication, dosage, and the time span of treatment. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. When rapid progressive dementia occurs in people over 40 years of age, accompanied by headache, seizures, or focal neurological deficits, with patchy or confluent T2 or FLAIR hyperintensity and evidence of CMBs or cSS, a diagnosis of CAA-RI should be suspected. (A) Confluent WMH. 30. Renard D, Tatu L, Collombier L, Wacongne A, Ayrignac X, Charif M, et al. Nationwide survey on cerebral amyloid angiopathy in Japan. 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. Vonsattel grading for CAA severity on neuropathology samples. A case of cerebral amyloid angiopathy-related inflammation with the rare apolipoprotein epsilon2/epsilon2 genotype. Epub 2022 Mar 14. 2. [33] Findings from several systematic reviews have shown that there is no obvious gender difference, but a slight male predominance was observed. Due to these atypical symptoms, advanced imaging is very meaningful for clinical diagnosis. [10,42,43] SWI is considered to be more reliable than T2 imaging, with greater reliability and sensitivity for detection of CMBs. [50,51] In these extreme cases, brain biopsy seems to be the only choice. 28. 7. Epub 2022 May 18. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity. 2016;36 (4): 1147-63. In autopsy series, the estimated prevalence of CAA is high (20-40 % in nondemented subjects; 50-60 % in dementia) [1]. 15 (8): 54. Castro Caldas A, Silva C, Albuquerque L, Pimentel J, Silva V, Ferro JM. Wermer MJH, Greenberg SM. Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. Bookshelf 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. 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. 2016YFC1300500-505). Traschtz A, Tzaridis T, Penner AH, Kuchelmeister K, Urbach H, Hattingen E, et al. Cerebral amyloid angiopathy-related inflammation (CAA-ri), also referred to as inflammatory cerebral amyloid angiopathy and A-related angiitis, is a distinct subset of cerebral amyloid angiopathy (CAA) characterized by an autoimmune reaction to cerebrovascular -amyloid deposits. Moreover, ABRA was considered to be different from ICAA because it has the same vascular destructive pathological changes as PACNS. Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. CAA-RI shares pathologic characteristics of CAA, which is A deposition in the cortical or leptomeningeal vessels, with positive Congo red staining. When the distinction is made, the difference lies in whether the inflammation is perivascular only (cerebral amyloid angiopathy-related inflammation or inflammatory cerebral amyloid angiopathy) or also involves and destroys the vessel wall (amyloid -related angiitis). Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Typical images of cerebral amyloid angiopathy-related inflammation. An official website of the United States government. [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. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. Piazza F, Greenberg SM, Savoiardo M, et al. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. Immunosuppressive therapy is effective both during initial presentation and in relapses. Second, vasculitis and the vascular areas affected by A co-localize. 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. Department of Neurology, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing 100730, China. However, anticoagulation was later suspended due to cerebral hemorrhage, and the patient was finally diagnosed with CAA-RI. CAA-RI is now widely recognized as a relatively rare and aggressive subtype of CAA with diverse clinical presentations and characteristic radiological findings. 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. MeSH Would you like email updates of new search results? 280 (2): 643-7. 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). You may search for similar articles that contain these same keywords or you may CT and MRI demonstrate an area of vasogenic edema involving the subcortical white matter 1. 63.

Medicine (Baltimore). Another option is to follow the patient up closely. Hemorrhage and white matter injury seen at imaging reflect vascular damage caused by the accumulation of A in vessel walls. [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. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. 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. 69. SWI or T2: which MRI sequence to use in the detection of cerebral microbleeds? The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). [22] Nevertheless, in our experience, this is not typical and may not be meaningful in clinical practice. However, some studies have questioned the idea.

CAA causes bleeding into the brain ( hemorrhagic stroke) and dementia. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex.

CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Our clinical experience also supports this conclusion [Figure 1]. Cerebrospinal fluid, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation. 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. [14] The dosage used is based on individual selection. [Cerebral Amyloid Angiopathy-Related Inflammation/Vasculitis]. Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare variant of CAA with autoimmune inflammation. National Library of Medicine Semin Arthritis Rheum. doi: 10.1212/WNL.0b013e3182a9f545. [19,29,30] Usually, B lymphocytes are fewer compared to T cells. Some of these diseases can be ruled out by T2 MRI or SWI. [22] The mainstream view is that granulomatous inflammation is the pathological hallmark of ABRA, but not of ICAA. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. Cancelloni V, Rufa A, Battisti C, De Stefano N, Mastrocinque E, Garosi G, Venezia D, Chiarotti I, Cerase A. Neurol Sci. 3. 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. Careers. 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. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. 62. A significant proportion of patients respond readily to treatment with corticosteroids, with or without a cytostatic agent,with improvement evident within a week or two of commencement of treatment. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. It would be more difficult to identify patients who also have a history of tumors. The distribution of CMBs does not follow the regional pattern of occipital dominance in non-inflammatory CAA. However, the average patient is a little younger than in non-inflammatory . Neurol Clin Pract. Epub 2014 Feb 11. 66. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al. [64] Another patient was first diagnosed with PRES, which was responsive to anti-edema intravenous steroid and antihypertensive therapy. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory effect. Acta Neuropathol. may email you for journal alerts and information, but is committed 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. 3.
