After treatment with corticoids, (D) WMH faded significantly. Curr Neurol Neurosci Rep. 2015 Aug;15(8):54. doi: 10.1007/s11910-015-0572-y. A Collet-Sicard syndrome due to internal carotid artery dissection associated with cerebral amyloid angiopathy-related inflammation. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. -, Wermer MJH, Greenberg SM. Epub 2014 Feb 11. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. Martucci M, Sarria S, Toledo M, Coscojuela P, Vert C, Siurana S, et al. 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). Perivascular and vascular inflammatory patterns without granulomas accounted for 22.5% of cases. Cerebral amyloid angiopathy is one of the leading causes of intracerebral hemorrhage and a significant contributor to age-related cognitive decline. 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. 35. 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. 3.

CAARI, also called amyloid--related angiitis, is a rare form of cerebral amyloid angiopathy with a predominantly vascular inflammation or angiitis. 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. [17] In this review, cognitive decline was the most common clinical manifestation, accounting for 48%, followed by seizures (32%), headache (32%), encephalopathy (27%), presenting as confusion or disturbance of consciousness, weakness (16%), and aphasia (14%). An alternative transcript of the Alzheimer's disease risk gene SORL1 encodes a truncated receptor. At present, the main recommendation is that high-dose glucocorticoids should be used. WMHs sometimes extend to the cortex with a mass effect showing hyperintensity in maps of apparent diffusion coefficient suggesting vasogenic edema. In the remainder, which accounts for 60% of all affected individuals, even with treatment severe disability or death are encountered 2. (2019) Frontiers in neurology.

The former represents the inflammatory form of CAA, while the latter is an independent disease or a subtype of PACNS associated with CAA. Chin Med J 2021;134:646654. An official website of the United States government. [14] The recurrence probability of CAA-RI has differed across studies. 2016 May;95(20):e3613. Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. 2016 May;95(20):e3613. Kimura A, Sakurai T, Yoshikura N, et al. Medicine (Baltimore). [17] While another systematic review showed that the functional outcome of most patients was not ideal. 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. If the brain biopsy result is negative, but the patient meets the clinicoradiological diagnostic criteria, the course of action remains uncertain. Immunosuppressive therapy is effective both during initial presentation and in relapses. Probable Cerebral Amyloid Angiopathy-Related Inflammation Associated With Sitravatinib: A Case Report. (2016) Medicine. Amyloid-Beta Related Angitiis and Reversible Cerebral Vasoconstriction Syndrome: A Case Report (P6.057). [47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. 22. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. The gold standard for diagnosis is autopsy or brain biopsy. Finally, a multi-center prospective cohort study, using unified standards for the collection of data, application of designed therapies, and follow-up strategy is necessary. 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). Hainline C, Rucker JC, Zagzag D, Golfinos JG, Lui YW, Liechty B, et al. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. 10. Some authors are consistent with the terms we have used here, while some call the two subtypes CAA-RI and ABRA. 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. Moreover, ABRA was considered to be different from ICAA because it has the same vascular destructive pathological changes as PACNS. [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. 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.

[22,31] In fact, both ICAA and ABRA can present with or without granulomatous inflammation. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. However, given the segmental distribution of the lesions, they may be missed by the biopsy, which will lead to a missed diagnosis. Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. Amyloid--related angiitis: a report of 2 cases with unusual presentations. 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. 70. In addition, when starting the treatment, infection needs to be ruled out first, to avoid pervasion due to corticosteroid therapy. Piazza F, Greenberg SM, Savoiardo M, Gardinetti M, Chiapparini L, Raicher I, et al. 68. Risk factor SORL1: from genetic association to functional validation in Alzheimer's disease. An intense perivascular inflammation with multinucleated giant cells is found in a minority of CAA patients, possibly those with an exaggerated inflammatory response to vascular leakages that occur from amyloid- laden arteries. Keyword Highlighting There have been few epidemiological studies on CAA-RI. Chinese Medical Journal134(6):646-654, March 20, 2021. 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.

Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis. However, biopsy is invasive; consequently, some criteria for the diagnosis of CAA-RI have been based on clinical and radiological data. Neurology 2013; 81:15961603. [54] Therefore, the presence of the APOE 4/4 genotype may be meaningful for the diagnosis of CAA-RI. Kang P, Bucelli RC, Ferguson CJ, Corbo JC, Kim AH, Day GS. Terminology [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. Because of the similarity between CAA-RI and ARIA, the first theory seems unreasonable. Thirteen percent of patients were affected with some forms of visual impairment. Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. 20. 2016;36 (4): 1147-63. . A definite diagnosis requires pathologic demonstration (such as biopsy or autopsy). Other differential diagnoses include viral or autoimmune encephalitis, cerebral venous thrombosis, acute disseminated encephalomyelitis (ADEM), Hashimoto encephalopathy, neurosarcoidosis, and acute toxic-metabolic leukoencephalopathy. doi: 10.1097/MD.0000000000003613. [6,66] In addition, these two conditions may be present concurrently. Some error has occurred while processing your request. 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. [70] The clinical features of relapse are widely distributed, among which the decline of cognitive function and encephalopathy are the most common symptoms.

Please enable it to take advantage of the complete set of features! 7. 1-6 It differs from more common noninflammatory forms of CAA . [1] The amyloid deposition results in fragile vessels that may manifest in brain bleeds. CT and MRI demonstrate an area of vasogenic edema involving the subcortical white matter 1. 3. CAA-RI shares pathologic characteristics of CAA, which is A deposition in the cortical or leptomeningeal vessels, with positive Congo red staining. 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 ].

Diagnosis, treatment, and follow-up of patients with 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]. AD patients who are apolipoprotein E (APOE) 4 gene carriers are more likely to develop ARIA after anti-A treatment,[25,26] in accordance with the findings in CAA-RI. Second, vasculitis and the vascular areas affected by A co-localize. The site is secure. [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. Moreover, the efficacy of treatment was evaluated by observational studies; consequently, more clinical trials and even randomized clinical trials are required. Many diseases with similar clinical manifestations should be carefully ruled out. Immunosuppressive therapy is effective both during initial presentation and in relapses. Although CAA-RI is relatively rare at present, it may become more common in future with the improvement of diagnostic techniques. 2022 Dec 3;22(1):449. doi: 10.1186/s12883-022-02979-6. Brain MRI lesions; Cerebral amyloid angiopathy; Cerebral small vessel disease; Inflammation; Review. Rarer, inflammatory forms (CAAi) are characterized by the presence of . Brain MRI 9 months later showed multiple discrete regions . Biomedicines. 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.

Genetics and molecular pathogenesis of sporadic and hereditary cerebral amyloid angiopathies. 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]. 41 (3): 446-448. Masrori P, Montagna M, De Smet E, Loos C. Posterior reversible encephalopathy syndrome caused by cerebral amyloid angiopathy-related inflammation. 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). 54. 2015 Sep;24(9):e245-50. (E) No significant changes with CMBs. 12. doi: 10.1016/j.jstrokecerebrovasdis.2015.04.042. A is deposited segmentally, but can be found in all those inflammation sites. Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. In the vast majority of cases (90%), microhemorrhages are present 1,2. [4] With the development of imaging technology, more clinical silent patients are identified by the classic imaging abnormalities, including multiple strictly lobar cerebral microbleeds (CMBs), cortical superficial siderosis (cSS) or cortical subarachnoid hemorrhage, and cortical atrophy.[3]. However, some studies have questioned the idea. (2015) Current neurology and neuroscience reports. Corovic A, Kelly S, Markus HS. [2023] In recent years, it has gradually come to be accepted that these two pathological types are essentially similar. Moreover, amyloid deposits start in the cortical areas and spread to the hippocampal areas at a later stage [32,33]. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex. Boncoraglio GB, Piazza F, Savoiardo M, Farina L, DiFrancesco JC, Prioni S, et al. 41. 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. 5. 6. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Semin Arthritis Rheum. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity. 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. [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. Acta Neuropathol 1974; 27:131137. 11. Probatory corticoid treatment resolved FLAIR changes . It would be more difficult to identify patients who also have a history of tumors. Validation of Clinicoradiological Criteria for the Diagnosis of Cerebral Amyloid Angiopathy-Related Inflammation. 66. 23. In autopsy series, the estimated prevalence of CAA is high (20-40 % in nondemented subjects; 50-60 % in dementia) [1]. Moosavi B, Torres C, Jansen G. Case 232: amyloid--related angiitis. This site needs JavaScript to work properly. Multimodality Review of Amyloid-related Diseases of the Central Nervous System. In order to make a diagnosis before histopathology, Chung et al[12] proposed the Boston criteria using clinicoradiological data in 2011. 47. However, many patients present with atypical symptoms other than those mentioned above, which may easily lead to an incorrect diagnosis. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. 37. An increase in inflammatory biomarkers has been observed in CAA-RI patients in different studies. DiFrancesco JC, Brioschi M, Brighina L, Ruffmann C, Saracchi E, Costantino G, et al. [44,45] However, sometimes the burden of CMBs is so obvious that hypointense lesions seen on SWI can also be identified on T2 or FLAIR images. 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. 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. -, Salvarani C, Hunder GG, Morris JM, Brown RD, Christianson T, Giannini C. A-related angiitis: comparison with CAA without inflammation and primary CNS vasculitis. [3] CAA related lobar ICH has been identified as the second most common form of spontaneous ICH following hypertensive angiopathy. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory 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. 64. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. 5. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Radiographics. [55] An APOE 4/4 homozygous patient with a rare SORL1 mutation has been reported. [15] In fact, these two types sometimes do coexist. 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. Castro Caldas A, Silva C, Albuquerque L, Pimentel J, Silva V, Ferro JM. [10,42,43] SWI is considered to be more reliable than T2 imaging, with greater reliability and sensitivity for detection of CMBs. 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. Epub 2022 May 18. Beta-amyloid 42 is a more effective reductant than beta-amyloid 40. Long-term follow up of patients with mild-to-moderate Alzheimer's disease treated with bapineuzumab in a phase III, open-label, extension study. BMC Neurol. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral hemorrhage. [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.

[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. [11] The most commonly used immunosuppressants are cyclophosphamide (33.9%), azathioprine (5.0%), mycophenolate mofetil (5.0%), methotrexate, immunoglobulin, and so on. 57. 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.
