Abstract
An 82-year-old woman had been suffering from progressive forgetfulness and abnormal speech and behavior for One month. Findings of the MRI of the head indicated scattered small cerebral infarcts in the cerebellum and in bilateral cerebral cortex/subcortical white matter. After admission, she experienced a subcortical hemorrhage, and the percentage of small cerebral infarcts increased over time. Based on the suspicion of central primary vasculitis or malignant lymphoma, we performed a brain biopsy targeting the right temporal lobe hemorrhage site, and the patient was diagnosed with cerebral amyloid angiopathy (CAA). We conclude that CAA can cause multiple small progressive cerebral infarcts.

Abstract
Cerebral amyloid angiopathy (CAA) is a common central nervous system (CNS) vasculopathy, which in some cases is associated with subacute encephalopathy, seizures, headaches, or strokes due to vascular inflammation directed against vascular amyloid accumulation. The pathological subtypes of inflammatory CAA include CAA-related inflammation (CAAri) with mostly perivascular lymphocytic infiltrates, or amyloid-beta (Aβ)-related angiitis (ABRA) with transmural granulomatous inflammation. CAAri and ABRA probably represent part of the spectrum of CNS vasculopathies, intermediate between CAA and primary CNS vasculitis, and they are closely related to Aβ-related imaging abnormalities and other manifestations of an inflammatory response directed against Aβ in the leptomeninges and cerebral parenchyma. As treatment strategies in Alzheimer's disease shift toward potentially effective antiamyloid immunotherapy, the incidence rate of inflammatory CAA (which is probably an underrecognized condition) is likely to increase. Its clinical features are varied and include subacute encephalopathy, behavioral symptoms, headaches, seizures, and focal neurological deficits, which necessitate a high degree of suspicion for this disorder that often responds to treatment. The recent definition of the typical clinical and radiological syndrome has increased its recognition and may eliminate the need for invasive histological sampling in at least some affected patients. Here we review the pathophysiology, clinical spectrum, and approach to diagnosis, and discuss illustrative cases that highlight the wide range of clinical presentations.

Cerebral Amyloid Angiopathy-Related Inflammation: A Single-Center Experience and a Literature Review. J Clin Med 2022; 11:jcm11226731. [PMID: 36431207 PMCID: PMC9692654 DOI: 10.3390/jcm11226731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 11/04/2022] [Accepted: 11/08/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Limited data exist regarding the prevalence of clinical, neuroimaging, and genetic markers among patients diagnosed with Cerebral Amyloid Angiopathy−related inflammation (CAA-ri). We sought to determine these characteristics in patients diagnosed in our center and to summarize available literature published either as single-case reports or small case series (<5 patients). Methods: We reported our single-center experience of patients diagnosed with CAA-ri according to international criteria during a seven-year period (2015−2022), and we abstracted data from 90 previously published cases. Results: Seven patients (43% women, mean age 70 ± 13 years) were diagnosed with CAA-ri in our center. The most common symptom at presentation was focal neurological dysfunction (71%), and the most prevalent radiological finding was the presence of T2/FLAIR white matter hyperintensities (100%). All patients were treated with corticosteroids and had a favorable functional outcome. Among 90 previously published CAA-ri cases (51% women, mean age 70 ± 9 years), focal neurological dysfunction was the most common symptom (76%), followed by a cognitive decline (46%) and headache (34%). The most prevalent neuroimaging findings were cerebral microbleeds (85%), asymmetric T2/FLAIR white matter hyperintensities (81%), and gadolinium-enhancing T1-lesions (37%). Genetic testing for the Apolipoprotein-E gene was available in 27 cases; 59% carried the APOE ε4/ε4 genotype. The majority of the published CAA-ri cases (78%) received corticosteroid monotherapy, while 17 patients (19%) were treated with additional immunosuppressive treatment. Favorable functional outcome following treatment was documented in 70% of patients. Conclusion: Improving the vigilance of clinicians regarding the early recognition and accurate diagnosis of CAA-ri is crucial for swift therapy initiation, which may result in improved functional outcomes.

Abstract
Purpose Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare potentially reversible encephalopathy associated with an autoimmune process against proteins deposited in the walls of cortical and leptomeningeal brain vessels. Definite diagnosis requires histopathological features of vascular inflammation and amyloid deposition from brain biopsy. Clinical-neuroradiological criteria have been recently introduced and validated to reduce the need for biopsy. The purpose of this paper is to report a historical retrospective review of clinical-neuroradiological follow-up of two patients with probable CAA-ri and five patients with a reasonably probable suspect of CAA-ri (4 females, 3 males, patient’s age at admission: 66–79 years) seen at our institution between 2007 and 2021, focusing on clinical and neuroradiological awareness to this entity and variable response to immunotherapy. Materials and methods Clinical features at presentation included subacute to acute confusion (6/7), seizures (4/7), cognitive impairment (5/7), and focal neurological signs (3/7). Neuroradiology included braincomputed tomography followed by magnetic resonance imaging. Infectious diseases and autoimmune workups were then performed. Results CSF analysis was performed in two patients. Cerebral angiography was performed in two patients, to rule out vascular malformations. Hemorrhagic posterior reversible encephalopathy syndrome has been suspected in two patients. Four patients underwent immunotherapy with corticosteroids followed by reduction of brain dysfunctions. Three patients did not undergo immunotherapy but underwent clinical and/or neuroradiological remission. Conclusions Patients with CAA-ri present a rare steroid-responsive acute to subacute brain dysfunction. Thus, it has to be known and recognized both clinically and neuroradiologically. Spontaneous clinical and/or neuroradiological improvement is possible in patients with mild symptoms.

Abstract
Epilepsy is classically considered a childhood disease. However, it represents the third most frequent neurological condition in the elderly, following stroke, and dementia. With the progressive aging of the general population, the number of patients with Late-Onset Epilepsy (LOE) is constantly growing, with important economic and social consequences, in particular for the more developed countries where the percentage of elderly people is higher. The most common causes of LOE are structural, mainly secondary to cerebrovascular or infectious diseases, brain tumors, trauma, and metabolic or toxic conditions. Moreover, there is a growing body of evidence linking LOE with neurodegenerative diseases, particularly Alzheimer's disease (AD). However, despite a thorough characterization, the causes of LOE remain unknown in a considerable portion of patients, thus termed as Late-Onset Epilepsy of Unknown origin (LOEU). In order to identify the possible causes of the disease, with an important impact in terms of treatment and prognosis, LOE patients should always undergo an exhaustive phenotypic characterization. In this work, we provide a detailed review of the main clinical and instrumental techniques for the adequate characterization of LOE patients in the clinical practice. This work aims to provide an easy and effective tool that supports routine activity of the clinicians facing LOE.

Abstract
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 are two recognized pathologically characterized variants: cerebral amyloid angiopathy-related inflammation (CAAri) and A beta-related angiitis (ABRA). Both variants produce a clinical picture that resembles primary angiitis of the CNS but is distinguished by a characteristic radiologic appearance. 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. This disorder typically responds to steroids but addition of other immune suppressants may be needed in some cases to control the disease.

Abstract
Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an immune-mediated disorder of the central nervous system characterized by an inflammatory response to amyloid-beta (Aβ) deposition within cerebral blood vessel walls. Immunosuppressive therapy is the mainstay of treatment. We present a case of CAA-ri in a subject already on immunosuppressive therapy after orthotopic heart transplantation (OHT). A 57-year-old man 8 months post-OHT for sarcoid cardiomyopathy developed headaches and staring spells while hospitalized for disseminated mycobacterial infection. His brain MRI revealed bi-hemispheric T2-weighted fluid-attenuated inversion recovery white matter hyperintensities and widespread microhemorrhages. Two weeks later, he developed gait ataxia and alterations in mental status, and repeat brain MRI showed more extensive confluent white matter hyperintensities. Leptomeningeal and cortex biopsy revealed changes consistent with amyloid angiitis, with perivascular and intramural histiocyte and lymphocyte collections. Mass spectroscopy confirmed Aβ deposition. Notably, the patient was on immunosuppression with daily 5 mg oral prednisone and tacrolimus before biopsy. After high-dose intravenous followed by oral corticosteroids, he demonstrated significant clinical and radiographic improvement. No relapse was noted despite the relatively rapid tapering of the prednisone therapy over 3 months, as mandated by his systemic infection. Despite the lack of a standard treatment protocol for CAA-ri, case series have reinforced the benefit of prolonged courses of glucocorticoids as single agent or in combination with other immunomodulatory agents. Hence, management of CAA-ri in patients with disseminated mycobacterial infections or OHT is challenging. Our case is unique, as review of existing literature has not revealed any similar cases of patients on chronic immunosuppression at the time of CAA-ri diagnosis, which one would expect to protect against this disorder. In addition, CAA-ri in association with cardiopulmonary sarcoidosis was not previously reported; however, a common immunopathogenic mechanism may exist.

Slightly Symptomatic Cerebral Amyloid Angiopathy-Related Inflammation with Spontaneous Remission in Four Months. Case Rep Neurol Med 2019; 2019:5308208.

Abstract
Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare variant of CAA with autoimmune inflammation. A 77-year-old female experienced light-headedness during walking and mild ataxic gait without any other objective neuropsychological deficits. Brain magnetic resonance imaging (MRI) revealed an area of abnormal signal and mild parenchymal swelling in the right parietal lobe, indicating vasogenic edema. T2⁎-weighted gradient echo imaging revealed some subcortical microbleeds in the same lesion. Based on the proposed criteria for CAA-ri, she was diagnosed with probable CAA-ri. After 4 months, the spontaneous improvement was noted in the patient's clinical and radiological findings. This report presents a rare and atypical case of CAA-ri in which the diagnosis was established after the patient underwent neuroimaging for only mild neurological symptoms, and the patient's clinical and radiological findings displayed spontaneous improvement. Despite typical and striking MRI findings of CAA-ri, this patient only presented a minimal symptom; this dissociation could highlight the significance of not misinterpreting any new neurological symptoms. Thus, increased availability of MRI and growing awareness of CAA-ri might result in more incidentally diagnosed cases in the future. Furthermore, this case suggests that it would be better to strictly monitor the clinical-radiological findings of patients with probable CAA-ri who only present with minimal symptoms without the initiation of immunosuppressive therapy.

Abstract
The superficial siderosis (SS) of the central nervous system (CNS) is a rare condition characterized by a wide range of neurological manifestations directly linked to an acquired iron-mediated neurodegeneration. First described more than 100 years ago, only recently SS has been divided into two distinct entities, according to the distribution of iron deposition in the CNS: cortical superficial siderosis (cSS) and infratentorial superficial siderosis (iSS). Here we describe an adult case of iSS, with detailed clinical and radiological features. Moreover, we extensively review the literature of SS, particularly focusing on the pathogenesis, clinical-radiological classification, diagnostic algorithm and treatment options of this rare condition.

Abstract
We report a case of inflammatory cerebral amyloid angiopathy (CAA) that led to rapid cognitive decline, seizures, visual hallucinations, hyperproteinorrachia and right hemispheric leukopathy. Brain biopsy gave the diagnosis of CAA. Although no inflammatory infiltrate was found in the biopsy sample, corticosteroids led to a regression of the radiological lesions without significant clinical improvement. CAA is a rare disease, defined by lesions of classical cerebral amyloid angiopathy and perivascular infiltrates in contact with the affected vessels. In cases of rapidly progressive dementia associated with leukopathy, inflammatory amyloid angiopathy should be considered as cognitive disorders may improve after immunosuppressive therapy.
