One case was initially suspected of PRES or cerebral venous sinus thrombosis and was treated with anticoagulant and steroid. [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]. The clinical presentation is usually acute or subacute 1,2, but may be chronic4. Cerebral amyloid angiopathy is often asymptomatic, which can cause dementia, intracranial hemorrhage, or transient neurological events. 15 (8): 54.

This case was reminiscent of ANCA-associated vasculitis, although the relationship between proteinase 3-antineutrophil cytoplasmic antibody and the pathogenesis of CAA-RI remains unclear. [12,14,18] The erythrocyte sedimentation rate was increased in 37.5% of patients, while C-reactive protein (CRP) was elevated in 60%. Xu YY, Chen S, Zhao JH, Chen XL, Zhang JW. [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. 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. sharing sensitive information, make sure youre on a federal 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. 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.

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. At present, the main recommendation is that high-dose glucocorticoids should be used. Neuroradiology. 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.

There are also cases of CAA-RI patients reported with genotype APOE 2/2 and APOE 2/3. 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. Cerebrospinal fluid Alzheimer's disease biomarkers in cerebral amyloid angiopathy-related inflammation. 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. Du Y, Liu C, Ma C, Xu X, Zhou X, Zhou H, et al. 63. CMBs: Cerebral microbleeds; WMH: White matter hyperintensity. MRI is the modality of choice in assessing these patients as it is able to visualize the characteristic peripheral microhemorrhages of cerebral amyloid angiopathy. 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 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.

The patient met the criteria for probable cerebral amyloid angiopathy-related inflammation (CAA-ri) and responded favorably to high-dose methylprednisolone. Conclusive diagnosis of CAA-RI requires histopathological confirmation, but it is invasive and has certain risks. 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. However, there are many atypical cases or cases without T2/SWI sequence that were initially misdiagnosed, in whom the diagnosis was later revised. Epub 2022 Aug 5. (A) Confluent WMH. [47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. Summary of MRI markers of small vessel disease and CAA to be evaluated in the project, including their definition, ratings scales and important points/modifications in their assessment specifically for clinical use within the Boston criteria v.2.0. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. 61. [61] Despite this, negative brain biopsy findings are insufficient to exclude the diagnosis of CAA-RI, because of the segmental distribution of pathological changes. Yamada M. Cerebral amyloid angiopathy: emerging concepts. Amyloid beta-related angiitis--a case report and comprehensive review of literature of 94 cases. It is worth noting that CAA-RI is a diagnosis by exclusion. Cerebral amyloid angiopathy (CAA) is a vasculopathy caused by deposition of amyloid (A) in the arteries and veins of the leptomeninges and cortex. Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. Child ND, Braksick SA, Flanagan EP, Keegan BM, Giannini C, Kantarci OH. 35. 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.

The Inflammatory Form of Cerebral Amyloid Angiopathy or "Cerebral Amyloid Angiopathy-Related Inflammation" (CAARI). 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. 67. 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. Ichimata S, Hata Y, Yoshida K, Nishida N. Autopsy of a multiple lobar hemorrhage case with amyloid--related angiitis. 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.
