[5] Unlike non-inflammatory CAA, acute or subacute onset of cognitive decline or behavioral changes are the most common symptom of CAA-RI. The Karolinska Imaging Dementia Study. This site needs JavaScript to work properly. WMHs sometimes extend to the cortex with a mass effect showing hyperintensity in maps of apparent diffusion coefficient suggesting vasogenic edema. Before Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Many diseases with similar clinical manifestations should be carefully ruled out. Moosavi B, Torres C, Jansen G. Case 232: amyloid--related angiitis. [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. See this image and copyright information in PMC. Andersen OM, Rudolph IM, Willnow TE. Fukasawa R, Shimizu S, Hirose D, Kanetaka H, Umahara T, Obikane H, et al. 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. (B) Strictly lobar CMBs. 23. Key Diagnostic Features: However, the prognosis of most untreated patients is poor. Cerebral amyloid angiopathy with related inflammation (CAA-RI) is an uncommon inflammatory subtype of CAA, with a variety of presentations that can mimic other focal and diffuse neurological disorders. [2023] In recent years, it has gradually come to be accepted that these two pathological types are essentially similar. (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): BMC Neurol. [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. 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. Anti-amyloid beta autoantibodies in cerebral amyloid angiopathy-related inflammation: implications for amyloid-modifying therapies. 2022 Apr;12(2):e4-e6. The patient met the criteria for probable cerebral amyloid angiopathy-related inflammation (CAA-ri) and responded favorably to high-dose methylprednisolone. Risk factor SORL1: from genetic association to functional validation in Alzheimer's disease. Curr Opin Neurol 2018; 31:2835. Cerebral amyloid angiopathy is one of the leading causes of intracerebral hemorrhage and a significant contributor to age-related cognitive decline. 62. It is conceivable that posterior reversible encephalopathy syndrome (PRES) is a very important differential diagnosis. Other differential diagnoses include viral or autoimmune encephalitis, cerebral venous thrombosis, acute disseminated encephalomyelitis (ADEM), Hashimoto encephalopathy, neurosarcoidosis, and acute toxic-metabolic leukoencephalopathy. Another option is to follow the patient up closely. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. Amyloid PET is also unavailable in most hospitals in China. Cerebral amyloid angiopathy is a common small vessel disease in the elderly involving vascular amyloid- deposition. Diagnosis, treatment, and follow-up of patients with cerebral amyloid angiopathy-related inflammation. The accuracy of the standard was verified, and yielded a sensitivity and specificity of 82% and 97% diagnosing probable CAA-RI, respectively. Teaching neuro: cerebral amyloid angiopathy-related inflammation presenting with isolated leptomeningitis. 40. Yamada M. Cerebral amyloid angiopathy: emerging concepts. Leptomeningeal and parenchymal vessels should be scored separately. Revesz T, Holton JL, Lashley T, Plant G, Frangione B, Rostagno A, Ghiso J.

[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. [Cerebral Amyloid Angiopathy-Related Inflammation/Vasculitis]. 2016;36 (4): 1147-63. 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. Yeh SJ, Tang SC, Tsai LK, Jeng JS. 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. A report of 2 cases. [18] The clinical and radiological manifestations may be initially relieved after glucocorticoid therapy, but can relapse after withdrawal of steroids or during dose decrease. 38. 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. [18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. [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. Brain MRI 9 months later showed multiple discrete regions . [28] CAA-RI is thought to be a spontaneous ARIA, while ARIA is considered to be iatrogenic CAA-RI. Cerebral amyloid angiopathy (CAA) is a condition in which proteins called amyloid build up on the walls of the arteries in the brain. (A) Confluent WMH. Chin Med J 2021;134:646654. Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Cerebral amyloid angiopathy. Moosavi B, Torres C, Jansen G. Case 232: Amyloid -related Angiitis. 60. (A) Confluent WMH. [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. This also reflects the importance of the SWI sequence. Reid AH, Maloney AF. Shams S, Martola J, Cavallin L, Granberg T, Shams M, Aspelin P, et al. Typical images of cerebral amyloid angiopathy-related inflammation. Giant cell arteritis and arteriolitis associated with amyloid angiopathy in an elderly mongol. A nationwide survey demonstrated that its prevalence is about 0.13 per 100,000 population in Japan. [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. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. 14. Objective. -, Yeh SJ, Tang SC, Tsai LK, Jeng JS. 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. Immune activation in amyloid--related angiitis correlates with decreased parenchymal amyloid- plaque load. Piazza F, Greenberg SM, Savoiardo M, et al. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex. In order to make a diagnosis before histopathology, Chung et al[12] proposed the Boston criteria using clinicoradiological data in 2011. Probatory corticoid treatment resolved FLAIR changes . http://creativecommons.org/licenses/by-nc-nd/4.0. After treatment with corticoids, (D) WMH faded significantly. Epub 2022 Mar 14. Association between immunosuppressive treatment and outcomes of cerebral amyloid angiopathy-related inflammation. [70] The clinical features of relapse are widely distributed, among which the decline of cognitive function and encephalopathy are the most common symptoms. Inflammatory cerebral amyloid angiopathy is a largely reversible inflammatory vasculopathy that develops in an acute or subacute fashion in reaction to amyloid protein deposition in the central nervous system blood vessels. There is currently no study giving recommendations on the choice of medication, dosage, and the time span of treatment. Once the diagnosis is made, glucocorticoids or even immunosuppressants should be adopted in order to improve the prognosis. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y. 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. Amyloid--related angiitis presenting as a uveomeningeal syndrome. Salvarani C, Brown RD Jr, Calamia KT, Christianson TJ, Huston J 3rd, Meschia JF, et al. Some authors are consistent with the terms we have used here, while some call the two subtypes CAA-RI and ABRA. 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. [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. There have been few epidemiological studies on CAA-RI. 13. Cerebral amyloid--related angiitis without cerebral microbleeds in a patient with subarachnoid hemorrhage. Traschtz A, Tzaridis T, Penner AH, Kuchelmeister K, Urbach H, Hattingen E, et al. Acute or subacute onset of cognitive decline or behavioral changes is the mos The case of an 85-year-old female with acute right hemiparesis with status epilepticus. . The site is secure. Biomedicines. 7. 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. 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. The aim of future research should focus on specific pathogenic mechanisms and inflammatory pathways to determine which types of CAA patients are prone to developing inflammation, whether other genes or alleles besides APOE 4 are also risk factors, how they play a role in the mechanism, and so on. [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. 51. [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. 8600 Rockville Pike Epub 2019 May 25. Cerebral amyloid angiopathy (CAA) is characterized by amyloid beta-peptide deposits within small- to medium-sized blood vessels of the brain and leptomeninges. [68] Other features include seizures, headaches, T2-weighted white matter hyperintense (WMH) lesions on magnetic resonance imaging (MRI), and pathological evidence of inflammation against vascular A, which is the hallmark of CAA. Growing numbers of patients have been reported with vascular inflammation associated with advanced cerebral amyloid angiopathy (59; 150). DiFrancesco JC, Touat M, Caulo M, Gallucci M, Garcin B, Levy R, et al. [13] Nevertheless, these criteria are still imperfect, as samples included in the validation trial was small. [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. [12,13] Because immunosuppressive therapy is effective for the disease, timely diagnosis and early commencement of therapy are very important. 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. 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. This highlights the significance of the T2/SWI sequences in differentiation. 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]. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). (2016) Journal of Alzheimer's disease : JAD. doi: 10.1111/bpa.13061. 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. 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.

Cerebral amyloid angiopathy-related inflammation presenting with rapidly progressive dementia, responsive to IVIg. Renard D, Wacongne A, Ayrignac X, Charif M, Fourcade G, Azakri S, et al. MeSH 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. [11] The most commonly used immunosuppressants are cyclophosphamide (33.9%), azathioprine (5.0%), mycophenolate mofetil (5.0%), methotrexate, immunoglobulin, and so on. Cerebral Amyloid Angiopathy and Cerebral Amyloid Angiopathy-Related Inflammation: Comparison of Hemorrhagic and DWI MRI Features. Would you like email updates of new search results? [14] The dosage used is based on individual selection. Moreover, ABRA was considered to be different from ICAA because it has the same vascular destructive pathological changes as PACNS.

Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions. [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. 2018;64(4):1113-1121. doi: 10.3233/JAD-180269.

[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]. 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. A Report of 2 Cases. sharing sensitive information, make sure youre on a federal 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. 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. 2022 Nov 19;10(11):2982. doi: 10.3390/biomedicines10112982.
