  • Serial Magnetic Resonance Imaging Changes of Pseudotumor Lesions In
    Yan et al. BMC Neurol (2021) 21:219 https://doi.org/10.1186/s12883-021-02250-4 CASE REPORT Open Access Serial magnetic resonance imaging changes of pseudotumor lesions in retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations: a case report Yuying Yan1, Shuai Jiang1, Ruilin Wang2, Xiang Wang3, Peng Li3* and Bo Wu1* Abstract Background: Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is an adult-onset rare monogenic microvasculopathy. Its typical neuroimaging features are punctate white matter lesions or pseudotumor alterations. RVCL-S is often under-recognized and misdiagnosed because of its rarity and similar imaging manifestations to multiple sclerosis or brain malignant mass. Case presentation: Here we report a case of a 36-year-old Chinese man who developed multiple tumefactive brain lesions spanning over two years leading to motor aphasia, cognitive decline, and limb weakness. He also presented with slight vision loss, and fundus fuorescein angiography indicated retinal vasculopathy. He underwent brain biopsies twice and showed no evidence of malignancy. Given the family history that his father died of a brain mass of unclear etiology, RVCL-S was suspected, and genetic analysis confrmed the diagnosis with a heterozygous insertion mutation in the three-prime repair exonuclease 1 gene. He was given courses of corticosteroids and cyclophospha- mide but received little response. Conclusions: The present case is one of the few published reports of RVCL-S with two-year detailed imaging data. Serial magnetic resonance images showed the progression pattern of the lesions. Our experience emphasizes that a better understanding of RVCL-S and considering it as a diferential diagnosis in patients with tumefactive brain lesions may help avoid unnecessary invasive examinations and make an earlier diagnosis.

  • Radiologically Isolated Syndrome: a Review for Neuroradiologists
    REVIEW ARTICLE Radiologically Isolated Syndrome: A Review for Neuroradiologists M. Hosseiny, S.D. Newsome, and D.M. Yousem ABSTRACT SUMMARY: Radiologically isolated syndrome refers to an entity in which white matter lesions fulfilling the criteria for multiple sclerosis occur in individuals without a history of a clinical demyelinating attack or alternative etiology. Since its introduction in 2009, the diagnostic criteria of radiologically isolated syndrome and its clinical relevance have been widely debated by neu- rologists and radiologists. The aim of the present study was to review the following: 1) historical evolution of radiologically iso- lated syndrome criteria, 2) clinical and imaging findings in adults and children with radiologically isolated syndrome, 3) imaging features of patients with radiologically isolated syndrome at high risk for conversion to MS, and 4) challenges and controversies for work-up, management, and therapeutic interventions of patients with radiologically isolated syndrome. ABBREVIATIONS: CIS ¼ clinically isolated syndrome; DIS ¼ dissemination in space; DIT ¼ dissemination in time; MAGNIMS ¼ Magnetic Resonance Imaging in MS; RIS ¼ radiologically isolated syndrome; RRMS ¼ relapsing-remitting multiple sclerosis; CADASIL ¼ cerebral autosomal dominant arteriopathy with sub- cortical infarcts and leukoencephalopathy; ADEM ¼ acute disseminated encephalomyelitis adiologically isolated syndrome (RIS) refers to an entity in patients are being evaluated for headache, trauma, or nonspecific Rwhich brain or spine MR

Materials and methods: T2-weighted and fluid-attenuated inversion recovery magnetic resonance images of 19 MS patients and 19 patients affected by CSVD were analysed for the presence and localisation of focal hyperintense white matter lesions. Lesions were subdivided into periventricular or non-periventricular (juxtacortical, subcortical, deep white matter and cerebellar) distributed. The number and localisation of lesions presenting with the central vein sign were recorded and compared between MS and CSVD lesions. Results: A total of 313 MS patients and 75 CSVD lesions were identified on T2-weighted and fluid-attenuated inversion recovery magnetic resonance images. The central vein sign was found in 128 MS lesions (40.9%), and the majority of them (71/128, 55.5%) had a periventricular distribution. The central vein sign was found in 22 out of 75 (29.3%) CSVD lesions, and periventricular distribution was seen in six out of 22 (27.2%) CSVD lesions. The difference in the proportion of white matter hyperintense lesions that presented with the central vein sign on susceptibility-weighted images in patients with MS and CSVD was statistically different, and a significantly higher number of MS patients presented with lesions with the central vein sign compared to CSVD patients.

Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Demyelinating lesions larger than 2 cm in diameter, with or without edema, are known as tumefactive demyelinating lesions (TDLs). Tey constitute a rare infammatory demyelinating disorder of the central nervous system. TDLs are typically characterized by headaches, cortical symptoms such as aphasia, hemiparesis, hemisensory defcits, seizures, and changes in consciousness. TDLs may occur in patients with or without an established diagnosis of MS or may occur as the initial demyelinating event. Tey may also be observed during follow-up in patients with MS, neuromyelitis optica, acute disseminated encephalomyelitis, or other autoimmune diseases. Diferential diagnosis includes brain tumors, abscess, granulomatous diseases, and vasculitis. In some cases, it may be very difcult to distinguish TDLs from a tumor, such that biopsy might be needed. However, no cases of asymptomatic TDLs have yet been reported in the literature. Hence, in this report, we present a case involving an asymptomatic TDL detected incidentally during magnetic resonance imaging in an 18-year-old man.

The latest revision of McDonald’s criteria allow for an earlier diagnosis of MS from a single baseline brain MRI providing improved sensitivity and specificity in the definite diagnosis of MS after and in monitoring the disease course; however, it lacks sensitivity to gray matter lesions and the first clinically isolated syndrome (CIS). Conventional MRI plays a key role in diagnosing diffuse damage throughtout the white matter. Advanced MRI techniques offer new biomarkers more closely linked to the pathological features of the disease, which are likely to improve the understanding of MS pathophysiology. However, the adoption of advanced techniques into clinical research and practice need to be refined and validated due to several limitations. of MS, including the more

In this work, we evaluated the pooled proportion of the CVS in brain MS lesions and to estimate the diagnostic performance of CVS to perform a diagnosis of MS and propose an optimal cut-off value. Methods: A systematic search was performed on publicly available databases (PUBMED/MEDLINE and Web of Science) up to 24 August 2020. Analysis of the proportion of white matter MS lesions with a central vein was performed using bivariate random-effect models. A meta-regression analysis was performed and the impact of using particular sequences (such as 3D echo-planar imaging) and post-processing techniques (such as FLAIR*) was investigated.

Occult cerebrovascular disease (CVD) is an important cause of late-onset seizures (LOS) and late- onset epilepsy (LOE). LOS/LOE are associated with a three-fold increased risk of subsequent clinical stroke. This relationship exists not only in later life, but with ‘late-onset’ seizures or epilepsy occurring from the fourth decade of life onwards. There is an increasing evidence for the importance of hypertension and cerebral small vessel disease in epileptogenesis, but there is a considerable need for further work to elucidate underlying mechanisms.

Recent evidence shows that beta amyloid-independent vascular changes and beta amyloid-dependent neuronal dysfunction both equally influence the disease, leading to loss of structural and functional connectivity. White matter changes (WMCs) in the brain are commonly observed in dementia patients. The effect of vascular factors on WMCs and the relationship between WMCs and severity of AD in patients remain to be clarified. We recruited 501 clinically diagnosed probable AD patients with a series of comprehensive neuropsychological tests and brain imaging.
