Brain MRI 9 months later showed multiple discrete regions . 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 is in most cases a non-inflammatory age-related condition that is associated with cerebral hemorrhage, infarcts, leukoencephalopathy and dementia. 2016;51(2):525-32. doi: 10.3233/JAD-151036. -, Reid AH, Maloney AF.

Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. CD4(+) T cells predominate in cerebrospinal fluid and leptomeningeal and parenchymal infiltrates in cerebral amyloid beta-related angiitis. The resultant vascular fragility tends to manifest in normotensive elderly patients as lobar intracerebral hemorrhage. Cerebral amyloid angiopathy related inflammation with prominent meningeal involvement. Angiography does not reveal evidence of vasculitis involving the large- or medium-sized vessels 6. There are also cases of CAA-RI patients reported with genotype APOE 2/2 and APOE 2/3. Biopsy obtained from the white matter showed no evidence of inflammation in one case. 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.

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]. Sallles E, Bonneville F, Delisle MB, Rigal E, Raposo N, Pariente J. CAA causes bleeding into the brain ( hemorrhagic stroke) and dementia. 11C-PiB PET imaging of encephalopathy associated with cerebral amyloid angiopathy. [54] Therefore, the presence of the APOE 4/4 genotype may be meaningful for the diagnosis of CAA-RI. 12. CAA can present on imaging as CAA (common), amyloidoma (uncommon), or inflammatory CAA (rare). Hemorrhage and white matter injury seen at imaging reflect vascular damage caused by the accumulation of A in vessel walls. 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. A spectrum from CAA to PACNS: pathological differences between CAA, ICAA, ABRA, and PACNS. - "Advancing diagnostic criteria for sporadic cerebral amyloid angiopathy: Study protocol for a multicenter MRI-pathology validation of Boston criteria v2.0" Vessel wall enhancement, however, is not specific for inflammation and may be seen with noninflammatory amyloid angiopathy 12. Medicine (Baltimore). 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. Kinnecom C, Lev MH, Wendell L, Smith EE, Rosand J, Frosch MP, et al. [22] Nevertheless, in our experience, this is not typical and may not be meaningful in clinical practice. Cerebral amyloid angiopathy and cerebral amyloid angiopathy-related inflammation: comparison of hemorrhagic and DWI MRI features.

Susceptibility-weighted imaging is more reliable than T2-weighted gradient-recalled echo MRI for detecting microbleeds. Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. 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. 65. 13. While changes are typically confined to the subcortical white matter, the involvement of the cortex is also encountered and predisposes to seizures 1,2. 66.

There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). [13] For patients diagnosed with probable CAA-RI by means of these criteria, immunosuppressive therapy can be given empirically to avoid brain biopsy. Our clinical experience also supports this conclusion [Figure 1]. Search for Similar Articles Table 4. 2022 Nov;43(11):6381-6387. doi: 10.1007/s10072-022-06299-y. Leptomeningeal enhancement may be a unique imaging manifestation in some cases with confirmed CAA-RI. 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. -, Yeh SJ, Tang SC, Tsai LK, Jeng JS. PMC However, given the segmental distribution of the lesions, they may be missed by the biopsy, which will lead to a missed diagnosis. [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. [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. government site. Shams S, Martola J, Cavallin L, Granberg T, Shams M, Aspelin P, et al. After treatment with corticoids, (D) WMH faded significantly. 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). 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, MRI, and florbetaben-PET in cerebral amyloid angiopathy-related inflammation. [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. 10. There are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). 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. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. Blechingberg J, Poulsen ASA, Kjlby M, Monti G, Allen M, Ivarsen AK, et al. Cerebral amyloid angiopathy (CAA) is a kind of disease in which amyloid (A) and other amyloid protein deposits in the cerebral cortex and the small blood vessels of the brain, causing . Other diagnostic indexes include the apolipoprotein E 4 allele, A and anti-A antibodies in cerebral spinal fluid and amyloid positron emission tomography. [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. It is worth noting that CAA-RI is a diagnosis by exclusion. The use of glucocorticoids and immunosuppressants improves prognosis. [58,59] Thus, a variant in SORL1 may lead to dysfunction of SorLA, eventually adding to the risk of CAA-RI.

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. 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. Reid AH, Maloney AF. If there is no response to corticosteroid therapy within 3 weeks, biopsy should be reconsidered to confirm the diagnosis. (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): 52. doi: 10.1212/CPJ.0000000000001162.

CAA-RI shares pathologic characteristics of CAA, which is A deposition in the cortical or leptomeningeal vessels, with positive Congo red staining. [19] Spontaneous remission has been reported in some cases,[7,71] the fundamentals of which are not yet known. The gold standard for diagnosis is autopsy or brain biopsy.

Imaging Findings of Cerebral Amyloid Angiopathy, A-Related Angiitis (ABRA), and Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Institution 25-Year Experience. 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. Amyloid can be confirmed when the Congo red-stained section shows green birefringence under polarized light. 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. Semin Arthritis Rheum. Leclercq L, Mechtouff L, Hermier M, Cho TH, Nighoghossian N, Ducray F. Intravascular large B-cell lymphoma mimicking cerebral amyloid angiopathy-related inflammation. 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. 4. CAARI, also called amyloid--related angiitis, is a rare form of cerebral amyloid angiopathy with a predominantly vascular inflammation or angiitis. Gera A, Witek N, Bailey M. Pearls & Oy-sters: CAA-related inflammation presents as subacute cognitive decline in a patient with Parkinson disease. 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. [33] Findings from several systematic reviews have shown that there is no obvious gender difference, but a slight male predominance was observed. [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]. In the vast majority of cases (90%), microhemorrhages are present 1,2. The asymmetry should not be due to past intracerebral hemorrhage to satisfy this criterion 4. Accessibility [1] The amyloid deposition results in fragile vessels that may manifest in brain bleeds. 3. doi: 10.1097/MD.0000000000003613. 50. [47,60] In the future, the significance of these indicators for the differential diagnosis of CAA-RI mimics should be studied. Brain MRI, particularly FLAIR and T2/SWI sequences, is the most important imaging modality for the identification of patients suspected of CAA-RI. Rarer, inflammatory forms (CAAi) are characterized by the presence of . Thus, in this review, we present the main pathological, clinical, neuroimaging, therapeutic, and prognostic features and the diagnostic criteria of CAA-RI to shed some light on its clinical practice, and then discuss issues that remain unresolved. [69] A systematic review of both pathological subtypes revealed that, during an average follow-up period of 24 months, 55% of patients eventually end up being asymptomatic or with mild disability. 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.

A 77-year-old female experienced light-headedness during walking and mild ataxic gait without any other objective neuropsychological deficits. (A) Confluent WMH. Thus, PACNS is on the list of differential diagnoses whenever multifocal hyperintensity is seen on FLAIR images, although it is a diagnosis of exclusion. Salvarani C, Morris JM, Giannini C, Brown RD Jr, Christianson T, Hunder GG. [72] It is worth noting that this case involved a patient who had been using immunosuppressive agents. [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. A Collet-Sicard syndrome due to internal carotid artery dissection associated with cerebral amyloid angiopathy-related inflammation. Immunosuppressive therapy is effective both during initial presentation and in relapses. 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).
