Leclercq L, Mechtouff L, Hermier M, Cho TH, Nighoghossian N, Ducray F. Intravascular large B-cell lymphoma mimicking cerebral amyloid angiopathy-related inflammation. It may also present with cognitive impairments, incidental . . [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 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. 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. Leptomeningeal enhancement may be a unique imaging manifestation in some cases with confirmed CAA-RI. Cerebral amyloid angiopathy-related inflammation with posterior reversible encephalopathy syndrome-like presentation: a case report. Careers. 3. MRI is the modality of choice in assessing these patients as it is able to visualize the characteristic peripheral microhemorrhages of cerebral amyloid angiopathy. HHS Vulnerability Disclosure, Help (2020) AJNR. Traschtz A, Tzaridis T, Penner AH, Kuchelmeister K, Urbach H, Hattingen E, et al. See this image and copyright information in PMC. [54] Therefore, the presence of the APOE 4/4 genotype may be meaningful for the diagnosis of CAA-RI. National Library of Medicine Beta-APP42 may activate mononuclear phagocytes in the brain and elicit inflammatory responses. Boncoraglio GB, Piazza F, Savoiardo M, Farina L, DiFrancesco JC, Prioni S, et al. 1. Cerebral amyloid angiopathy (CAA)related inflammation (CAA-RI) affects brain parenchyma, but rarely involves leptomeninges, a likely immunogenic consequence of -amyloid peptide expressed in the walls of small and medium sized cerebral vessels. Abeta-related angiitis: primary angiitis of the central nervous system associated with cerebral amyloid angiopathy. CAA is defined by histopathologydeposition of -amyloid in the cerebrovasculatureand through the 1980s the disorder was only diagnosed in patients with available brain tissue from hematoma evacuation, biopsy, or most commonly postmortem examination. Validation of Clinicoradiological Criteria for the Diagnosis of Cerebral Amyloid Angiopathy-Related Inflammation. It may also be possible that, due to sampling error on biopsy,the pathological diagnosis does not reflect the global picture depicted on imaging 6. J Alzheimers Dis. Unable to load your collection due to an error, Unable to load your delegates due to an error. Since there is no A deposition in the blood vessels supplying the spinal cord, symptoms of myelopathy have not been reported in ICAA and ABRA; thus, PACNS is a more likely diagnosis when symptoms involving the spinal cord occur. 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. [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.

[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. (C) No enhancement was seen. 34. Cerebral amyloid angiopathy related inflammation with prominent meningeal involvement. In addition, the treatment of infection and other comorbidities should be considered in such cases. Before Clipboard, Search History, and several other advanced features are temporarily unavailable.

Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. CAA can present on imaging as CAA (common), amyloidoma (uncommon), or inflammatory CAA (rare). [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. However, clinicoradiological diagnostic criteria have been proposed for cerebral amyloid angiopathy related inflammation 4. at least one of these clinical features not directly attributable to an acute intracerebral hemorrhage: MRI with white matter hyperintensities (unifocal or multifocal, corticosubcortical or deep) that extend to the immediately subcortical white matter, at least one of these corticosubcortical hemorrhagic lesions: cerebral macrobleed, cerebral microbleed, or cortical superficial siderosis, absence of neoplastic, infectious, or other cause. Data is temporarily unavailable. 2015 Sep;24(9):e245-50. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid (A)-related angiitis. Yeh SJ, Tang SC, Tsai LK, Jeng JS. 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. 15 (8): 54.

(C) No enhancement was seen. Neurol Clin Pract. Course of cerebral amyloid angiopathy-related inflammation. Clinicians should have a comprehensive understanding of the disease and order an MRI with multiple sequences, including T2 or SWI, in patients with suspected CAA-RI, particularly in those cases whose T2/FLAIR images show hypointense dots. 8600 Rockville Pike Cerebral amyloid angiopathy. Other synonyms used for this entity include cerebral amyloid inflammatory vasculopathy,amyloid angiopathy and granulomatous angiitis of the central nervous system,cerebral amyloid angiitis, primary angiitis of the central nervous system associated with cerebral amyloid angiopathy, and cerebral amyloid angiopathy associated with giant cell arteritis9. These cases emphasize that CAA-RI is a diagnosis by exclusion. At present, the main recommendation is that high-dose glucocorticoids should be used. [17] While another systematic review showed that the functional outcome of most patients was not ideal. A engulfed in macrophages can be observed at times. Aimen Moussaddy, Ariel Levy, Daniel Strbian, Sophia Sundararajan, France Berthelet, Sylvain Lanthier. [20] Currently, most evidence favors the hypothesis that inflammation is triggered by an autoimmune response to the deposited A protein. Xu YY, Chen S, Zhao JH, Chen XL, Zhang JW. 2016YFC1300500-505). Therefore, other biomarkers are needed to enrich the criteria. Cerebral amyloid angiopathy-related inflammation: a case report presenting with a rare variant in SORL1 gene. The https:// ensures that you are connecting to the 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).

Pathogenetical subtypes of recurrent intracerebral hemorrhage: designations by SMASH-U classification system. 16. Clinical Presentation: Patients typically present with seizures, headache, and strokelike episodes, along with an acute or subacute decline in cognitive status. [12,13] Because immunosuppressive therapy is effective for the disease, timely diagnosis and early commencement of therapy are very important. Accessibility The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral hemorrhage. CAA causes bleeding into the brain ( hemorrhagic stroke) and dementia. 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. The possible mechanism is that APOE 4 increases A deposition, and has a pro-inflammatory effect. Child ND, Braksick SA, Flanagan EP, Keegan BM, Giannini C, Kantarci OH. First, ABRA has the same radiological characteristics as ICAA, which are not common in PACNS. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity.

[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%). Besides, the study did not propose a specific treatment or plan for further examination for patients meeting a diagnosis of possible CAA-RI. Nat Rev Neurol. Please enable it to take advantage of the complete set of features! Semin Arthritis Rheum. 1. Almost half of those with ARIA-E also developed ARIA-H, with co-located lesions. [15] In fact, these two types sometimes do coexist. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex.

[18] No difference in outcome was found between patients receiving mono-therapy of corticosteroid and patients receiving a combination of immunosuppressant and corticosteroid therapy. [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. 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. [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]. 8600 Rockville Pike Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. 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. 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. Acute ischemic lesions in cerebral amyloid angiopathy-related inflammation. It would be more difficult to identify patients who also have a history of tumors.

Cerebral amyloid angiopathy-related inflammation in the immunosuppressed: a case report. 10. Eng JA, Frosch MP, Choi K, Rebeck GW, Greenberg SM. 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. Validation of clinicoradiological criteria for the diagnosis of cerebral amyloid angiopathy-related inflammation. Due to these atypical symptoms, advanced imaging is very meaningful for clinical diagnosis. However, there are many atypical cases or cases without T2/SWI sequence that were initially misdiagnosed, in whom the diagnosis was later revised. 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). 2022 Oct 13;58(10):1446. doi: 10.3390/medicina58101446. The rare forms of inflammatory angiopathy attributed to A, A-related angiitis . [14] Based on the criteria of leptomeningeal enhancement, the sensitivity and specificity of recognizing CAA-RI from CAA patients are reported to be 70.4% and 92.6%, respectively.

[58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI. 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. Rarer, inflammatory forms (CAAi) are characterized by the presence of . Brain Pathol. Many diseases with similar clinical manifestations should be carefully ruled out. However, some studies have questioned the idea. Probable Cerebral Amyloid Angiopathy-Related Inflammation Associated With Sitravatinib: A Case Report.

Amyloid-related imaging abnormalities in patients with Alzheimer's disease treated with bapineuzumab: a retrospective analysis. [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. [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. 69. After several recurrences, WMH and CMBs progressed and long-term follow-up led to a diagnosis of CAA-RI. In fact, in a subgroup of patients, spontaneous remission is encountered 1. A case of cerebral amyloid angiopathy-related inflammation with the rare apolipoprotein epsilon2/epsilon2 genotype. Accessibility Sperling R, Salloway S, Brooks DJ, Tampieri D, Barakos J, Fox NC, et al. 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. Saliou V, Ben Salem D, Ognard J, Guellec D, Marcorelles P, Rouhart F, et al. Hemorrhage and white matter injury seen at imaging reflect vascular damage caused by the accumulation of A in vessel walls. [18] It can be concluded that these pathologically similar diseases constitute a spectrum from CAA to PACNS [Table 1]. Acute or subacute onset of cognitive decline or behavioral changes is the mos [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. Imaging findings of cerebral amyloid angiopathy, Abeta-related angiitis (ABRA), and cerebral amyloid angiopathy-related inflammation: a single-institution 25-year experience. CAA-RI shares pathologic characteristics of CAA, which is A deposition in the cortical or leptomeningeal vessels, with positive Congo red staining.

Kirshner et al[8] reported a CAA-RI patient with pathologically confirmed grade III anaplastic astrocytoma. Hence, in such cases, close follow-up should be performed. Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. Thus, it needs to be established whether excessive immune suppression would have an adverse effect on the long-term prognosis of patients. and transmitted securely. Susceptibility-weighted imaging is more reliable than T2-weighted gradient-recalled echo MRI for detecting microbleeds. Cerebral amyloid angiopathy and Alzheimer disease - one peptide, two pathways. (A) Confluent WMH. 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. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Some of these diseases can be ruled out by T2 MRI or SWI. 5. Cerebral amyloid angiopathy associated with inflammation: a systematic, 18. Would you like email updates of new search results? If only routine sequences are performed, it is easy to mistake WMH as the only image manifestation and consequently delay diagnosis and treatment. [1] The amyloid deposition results in fragile vessels that may manifest in brain bleeds. [Cerebral Amyloid Angiopathy-Related Inflammation/Vasculitis]. WMH and vasogenic edema accompanied by a mass effect make brain tumors a highly suspected differentiation. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. A Report of 2 Cases. 1 Introduction of the imaging-based Boston criteria for diagnosis of CAA in the 1990s 2, 3 [17] Steroid therapy is also effective during recurrence, but increased microbleeds may be detected with T2/SWI sequences in that case.
