Moosavi B, Torres C, Jansen G. Case 232: amyloid--related angiitis. Validation of Clinicoradiological Criteria for the Diagnosis of Cerebral Amyloid Angiopathy-Related Inflammation. 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. 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. Melzer N, Harder A, Gross CC, Wolfer J, Stummer W, Niederstadt T, et al. 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. [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. 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. 72. 29. Yamada M. Cerebral amyloid angiopathy: emerging concepts. Our clinical experience also supports this conclusion [Figure 1]. CAA is an important cause of lobar intracerebral hemorrhage in older adults [ 1,2 ]. Findings supporting CAA-RI include patchy or confluent T2 hyperintensity of subcortical white matter lesions, which are mostly asymmetric, in addition to the presence of multiple, strictly lobar CMBs and cSS on T2 or SWI, which is also a typical finding in CAA [Figure 1]. 8. Amyloid--related angiitis: a report of 2 cases with unusual presentations. It is conceivable that posterior reversible encephalopathy syndrome (PRES) is a very important differential diagnosis. 3. doi: 10.1097/MD.0000000000003613. 4. The .gov means its official. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. Yeh SJ, Tang SC, Tsai LK, Jeng JS. It would be more difficult to identify patients who also have a history of tumors. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Second, vasculitis and the vascular areas affected by A co-localize. It is worth noting that CAA-RI is a diagnosis by exclusion. A case of cerebral amyloid angiopathy-related inflammation with the rare apolipoprotein epsilon2/epsilon2 genotype. 68. Key Diagnostic Features: CAA can present on imaging as CAA (common), amyloidoma (uncommon), or inflammatory CAA (rare). 2014 Aug;44(1):86-92. doi: 10.1016/j.semarthrit.2014.02.001. 2016YFC1300500-505). (C) No enhancement was seen. Vonsattel grading for CAA severity on neuropathology samples. Angiography does not reveal evidence of vasculitis involving the large- or medium-sized vessels 6. Immunosuppressive therapy is effective both during initial presentation and in relapses. Cerebral amyloid angiopathy (CAA) is a common small vessel disease characterized by the deposition of amyloid (A) protein mainly in the media and adventitia of small- and medium-sized leptomeningeal and cortical blood vessels. Cerebral Amyloid Angiopathy and Cerebral Amyloid Angiopathy-Related Inflammation: Comparison of Hemorrhagic and DWI MRI Features. Coulette S, Renard D, Lehmann S, Raposo N, Arquizan C, Charif M, et al. [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. Epub 2014 Feb 11. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex. Eng JA, Frosch MP, Choi K, Rebeck GW, Greenberg SM. The work cannot be changed in any way or used commercially without permission from the journal. (E) No significant changes with CMBs. Moreover, amyloid deposits start in the cortical areas and spread to the hippocampal areas at a later stage [32,33]. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. If the brain biopsy result is negative, but the patient meets the clinicoradiological diagnostic criteria, the course of action remains uncertain. Many diseases with similar clinical manifestations should be carefully ruled out. Chung KK, Anderson NE, Hutchinson D, Synek B, Barber PA. Cerebral amyloid angiopathy related inflammation: three case reports and a. If there is no response to corticosteroid therapy within 3 weeks, biopsy should be reconsidered to confirm the diagnosis. These cases emphasize that CAA-RI is a diagnosis by exclusion. Savoiardo M, Erbetta A, Storchi G, Girotti F. Case 159: cerebral amyloid angiopathy-related inflammation. Moreover, ABRA was considered to be different from ICAA because it has the same vascular destructive pathological changes as PACNS. Please enable scripts and reload this page.

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. [18] It can be concluded that these pathologically similar diseases constitute a spectrum from CAA to PACNS [Table 1]. Disclaimer. Bogner S, Bernreuther C, Matschke J, Barrera-Ocampo A, Sepulveda-Falla D, Leypoldt F, et al. CAA-RI is now widely recognized as a relatively rare and aggressive subtype of CAA with diverse clinical presentations and characteristic radiological findings. In patients who respond to treatment, imaging follow-up demonstrates regression of the aforementioned inflammatory findings. [13] Nevertheless, these criteria are still imperfect, as samples included in the validation trial was small. [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]. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. 34 (10): 1958. An official website of the United States government.

Validation of clinicoradiological criteria for the diagnosis of cerebral amyloid angiopathy-related inflammation. Cenina AR, De Leon J, Tay KY, Wong CF, Kandiah N. Cerebral amyloid angiopathy-related inflammation presenting with rapidly progressive dementia, responsive to IVIg. 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. 42. It also remains unclear what should be done for those diagnosed with possible CAA-RI, and whether they still need to undergo brain biopsy. 56. 37. FOIA 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]. Cerebral amyloid angiopathy related inflammation (CAA-ri) is a rare encephalopathy resulting from perivascular inflammation after -amyloid (A) deposition in cerebral vessels leading to progressive dementia, focal neurological signs, seizures and intracerebral hemorrhages. 2022 Nov 14;11(22):6731. doi: 10.3390/jcm11226731. [19] Spontaneous remission has been reported in some cases,[7,71] the fundamentals of which are not yet known. Conclusive diagnosis of CAA-RI requires histopathological confirmation, but it is invasive and has certain risks. [14] The dosage used is based on individual selection. 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. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446.

Kirshner et al[8] reported a CAA-RI patient with pathologically confirmed grade III anaplastic astrocytoma. doi: 10.1212/CPJ.0000000000001162. Federal government websites often end in .gov or .mil. Curr Opin Neurol 2018; 31:2835. Inflammatory cerebral amyloid angiopathy. Thirteen percent of patients were affected with some forms of visual impairment. The former represents the inflammatory form of CAA, while the latter is an independent disease or a subtype of PACNS associated with CAA.

J Clin Med. Thus, amyloid positron emission tomography (PET) might be important for the diagnosis of CAA-RI, by showing sites with markedly elevated amyloid deposition.[11,52,53]. [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. 2015 Sep;24(9):e245-50. After treatment with corticoids, (D) WMH faded significantly.

[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. [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. 11. [18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. That is, 50% of all cases showed overlap between ICAA and ABRA patterns. 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. 11. Subcortical white matter will demonstrate usually a solitary area of low density with localized mass effect 1,2. 63. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. 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. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. The use of glucocorticoids and immunosuppressants improves prognosis. 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. Discussion This report of neurologic autoimmunity in a patient receiving sitravatinib opens new lines of inquiry into the pathophysiology of CAA-ri. [70] The clinical features of relapse are widely distributed, among which the decline of cognitive function and encephalopathy are the most common symptoms. Ann Neurol 2013; 73:449. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. In particular, amiloid tracers revealed higher retention in CAA patients, correlation with cerebral bleed, the ability to differentiate between CAA and other related conditions (such as Alzheimer's disease) and a correlation with some cerebrospinal fluid biomarkers. Epub 2022 Aug 5. 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. Disclaimer. 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).

[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. CAA causes bleeding into the brain ( hemorrhagic stroke) and dementia. Leptomeningeal and parenchymal vessels should be scored separately. Careers. [12,14,18] The erythrocyte sedimentation rate was increased in 37.5% of patients, while C-reactive protein (CRP) was elevated in 60%. [20] The incidence of ARIA gradually increased with an increase in the therapeutic antibody dose. [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.

Although originally defined as a clinicopathologic diagnosis, it can now often be diagnosed based on clinicoradiologic criteria, though confirmation with brain and meningeal biopsy is still required in some cases. 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. WMHs sometimes extend to the cortex with a mass effect showing hyperintensity in maps of apparent diffusion coefficient suggesting vasogenic edema. 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.

Cerebral amyloid angiopathy (CAA) is characterized by amyloid beta-peptide deposits within small- to medium-sized blood vessels of the brain and leptomeninges. [15] In fact, these two types sometimes do coexist. [47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. 1. The term "inflammatory cerebral amyloid angiopathy" can be used as an umbrella term encompassing two subtypes:cerebral amyloid angiopathy-related inflammation and amyloid -related angiitis2,6. Imaging findings of cerebral amyloid angiopathy, Abeta-related angiitis (ABRA), and cerebral amyloid angiopathy-related inflammation: a single-institution 25-year experience. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion. 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. [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. In general, the same patient group affected by cerebral amyloid angiopathy is affected, and thus most patients are elderly, typically 60-80 years of age. [14,29] Finally, in terms of clinical manifestations and prognosis, there was no difference between the two pathological subtypes of CAA-RI. 2016;36 (4): 1147-63.

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). (2016) Journal of Alzheimer's disease : JAD. 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. Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation. The incidence of multiple lobar CMBs, as well as the total number of CMBs is significantly higher in CAA-RI patients. CAARI, also called amyloid--related angiitis, is a rare form of cerebral amyloid angiopathy with a predominantly vascular inflammation or angiitis. The clinical presentation is usually acute or subacute 1,2, but may be chronic4. Cerebral amyloid angiopathy-related inflammation: imaging findings and clinical outcome. [64] Another patient was first diagnosed with PRES, which was responsive to anti-edema intravenous steroid and antihypertensive therapy. (2016) Neurology. 21. PACNS usually occurs in younger patients (mean age, 45 years), while CAA-RI is common in slightly older people. 1 Introduction of the imaging-based Boston criteria for diagnosis of CAA in the 1990s 2, 3 17. 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.

There are still many questions related to CAA-RI that require investigation. [50,51] In these extreme cases, brain biopsy seems to be the only choice. [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. 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.
