tumefactive ms

OBJECTIVE: To investigate the clinical diagnosis and treatment of tumefactive multiple sclerosis (TMS). METHODS: Clinical data, laboratory and imaging examinations, and treatment of three patients with TMS were retrospectively analyzed. Data were further analyzed in relation to the literature. RESULTS: All three patients had acute or subacute onset with large lesions on imaging, which were difficult to differentiate from tumors. Two cases had relapses on follow-up and one case had a stereotactic biopsy...

Balo's concentric sclerosis (BCS) is a rare subtype of multiple sclerosis. Advanced MRI metrics, such as magnetization transfer ratio (MTR), fractional anisotropy (FA), mean diffusivity (MD), and the ratio of total N-acetylaspartate concentration/total creatine concentration (tNAA/tCr) using proton magnetic resonance spectroscopy (1 H-MRS), are commonly used in research studies to investigate the effect of a disease modifying therapy (DMT). We report a patient diagnosed with BCS, receiving ocrelizumab, and provide a comparison of the lesion volume, T1-gadolinium lesion volume, MTR, FA, MD, and MRS metrics at baseline, 6- and 12-month follow-up...

Infectious and inflammatory dermatoses featuring skin lesions with loss of tissue expose skin layers to microbial invasions, disrupt the normal skin microbiome, and potentially lead to sepsis. However, literature data on the incidence of cutaneous-onset sepsis are scarce. This retrospective observational study assessed hospital admissions for primary skin lesions without bacterial infections and sepsis during 2020-2022 in the largest emergency hospital in NE Romania. Of 509 patients, 441 had infected lesions, 78 had sepsis caused by venous ulcers from microbial eczema cellulitis, superinfected bullous dermatoses, erysipelas, and erythroderma...

Tumefactive demyelinating lesions (TDLs) can present as an isolated clinical incidence or could represent the initial presentation of multiple sclerosis. Radiological TDLs are characterized by large tumors like >2 cm space-occupying lesions with mass effect and perilesional edema. Diagnosis is based on MRI imaging and extensive work to exclude other causes and a biopsy of the lesion is often required. First-line treatments include pulsed methylprednisolone. We present a case of a refractory TDL treated successfully with therapeutic plasma exchange...

BACKGROUND: Many different pathologies may underlie tumefactive demyelinating lesions. Identifying clinical and radiologic distinguishing features before pathologic examination is essential for diagnosis and treatment. In this study, we aimed to determine the clinical and radiologic features affecting the etiology and disease course of patients with tumefactive lesions (TDL). MATERIALS AND METHODS: We included 35 clinicoradiologically or histologically diagnosed TDL patients in our center over 11 years...

Tumefactive multiple sclerosis (TMS) is characterized by large demyelinating brain lesions. This was a retrospective cohort study of 67 patients with TMS between January 2015-2023, examining different disease modifying therapy impact on expanded disability scale score change at follow-up. Median age was 36 with a female predominance. Mean EDSS was 3.3 ± 2.3 at TMS onset, 2.1 ± 1.9 at year one, and 2.1 ± 1.9 at last follow-up. A multilinear regression model found higher presentation EDSS and post-diagnosis non-B-cell high efficacy therapies were each independently associated with higher EDSS at last follow up...

Tumefactive multiple sclerosis (MS) is a subtype of atypical and rare MS that presents with tumor-like lesions in the central nervous system. The lesions may demonstrate a mass effect, edema, with ring enhancement. They can be mistaken for brain tumors or brain abscesses radiologically and clinically. Here we describe an instructive case of a 55-year-old woman with tumefactive MS who presented with occasional numbness in her right arm and leg, headache, thought confusion, and blurred vision for 2 years.

Idiopathic intracranial hypertension (IIH) and multiple sclerosis (MS) are rare neurological disorders that largely affect females within the reproductive age group. The clinical pictures of both diseases can overlap, which therefore places great importance on accurately studying and reporting their concurrence. Therein, we report a case of IIH presenting and progressing simultaneously with MS. This young, previously healthy female presented with the primary complaint of a severe right-sided headache associated with blurred vision and a finding of papilledema...

We present a case and video of a 31-year-old man with biopsy-confirmed tumefactive demyelination affecting the right internal capsule causing left hemiplegia, excessive yawning, and the curious but well-described phenomenon of parakinesia brachialis oscitans (PBO) with transient tonic elevation of his paralyzed arm while yawning. PBO is most commonly reported in ischemic stroke with internal capsule or pontomedullary brainstem lesions. Our case uniquely demonstrates this phenomenon in the case of tumefactive demyelination...

Tumefactive demyelinating lesions (TDL), characterized by large (≥ 2 cm) demyelinating lesions mimicking tumors, are a rare manifestation of the central nervous system inflammatory demyelinating diseases (CNS-IDD). Distinguishing TDL from other brain lesions can be challenging, often necessitating biopsy or advanced diagnostics. The natural history of TDL varies among races. This study aimed to assess demographics, clinical and radiological features, laboratory findings, management, and outcomes of Thai patients with TDL...

BACKGROUND: Relapsing or recurrent tumefactive demyelination is rare and has not been studied beyond individual case reports. OBJECTIVE: We examined the clinical course, neuroimaging, cerebrospinal fluid (CSF), treatment and outcomes of patients with recurrent tumefactive demyelinating lesions (TDLs). METHODS: We used PubMed to identify reports of recurrent TDLs and included the details of an additional, unpublished patient. RESULTS: We identified 18 cases (11F, 7 M)...

This case report highlights the diagnostic challenges encountered in a 30-year-old female presenting with fever followed by Wernicke's aphasia without right-sided weakness, ultimately diagnosed as tumefactive demyelination (TD). TD is a rare neurological condition often misidentified as brain tumors or inflammatory disorders. The case emphasizes the importance of precise differentiation through advanced magnetic resonance imaging, showing restricted diffusion at lesion edges and the absence of gadolinium enhancement...

In both children and adults, magnetic resonance imaging of the brain in cases of multiple sclerosis (MS) has typical indications, where one of the key points for differentiating between demyelinating processes and place-taking processes is the fact that most of the lesions that appear in multiple sclerosis do not cause a mass effect or much edema around them. There are several uncommon subtypes of multiple sclerosis that can appear specifically in adolescents, presenting with a stormy clinical course and accompanied by brain lesions that resemble space-occupying lesions...

BACKGROUND: Although myelin-oligodendrocyte-glycoprotein (MOG)-antibody-associated disease (MOGAD) has been considered a more favorable demyelinating central nervous system disorder, recent data evidence that some patients might experience severe relapses and high disability. Actual treatment-options are acquired mostly from anti-aquaporin-4-antibody-positive neuromyelitis optica spectrum disorder and rely on clinical experience. Therefore, treatment of aggressive forms of MOGAD can be challenging...

The epidemic of COVID-19 is mainly manifested by respiratory symptoms caused by SARS-CoV-2 infection. Recently, reports of central nervous system diseases caused or aggravated by SARS-CoV-2 infection are also increasing. Thus, the COVID-19 pandemic poses an unprecedented challenge to the diagnosis and management of neurological disorders, especially to those diseases which have overlapping clinical and radiologic features with each other. In this study, a 31-year-old female patient had been diagnosed with relapsing-remitting multiple sclerosis (RRMS) initially and subsequently developed tumefactive demyelinating lesions (TDLs) following an infection with SARS-CoV-2...

PURPOSE: Tumefactive demyelination (TD) lesion and its subtype Balo's concentric sclerosis (BCS), are rare manifestations of central nervous system demyelinating disease. Because of its rarity, physicians might hesitate in reaching a diagnosis or initiating steroid pulse therapy. This study aims at pinpointing the key neuroimaging features to distinguish TD lesions from surgical conditions, and illustrating the clinical outcomes of patients with TD lesions. CASE REPORT: Two of the three patients had solitary TD lesions, one 47-year-old man presenting with newly onset seizure and another 54-year-old women suffering from progressive hemiparesis...

In ancient times, Withania coagulans Dunal was used as a therapeutic plant for the treatment of several diseases. This report aims to examine the effect of Agrobacterium tumefactions -mediated transformation of W. coagulans with the rolA gene to enhance secondary metabolite production, antioxidant activity, and anticancer activity of transformed tissues. Before transgenic plant production, the authors designed an efficient methodology for in vitro transformation. In this study, leaf explants were cultured on Murashage and Skoog (MS) media containing different amounts of naphthalene acetic acid (NAA) and benzyl adenine (BA)...

OBJECTIVES: Parakinesia brachialis oscitans (PBO) is the involuntary movement of an otherwise paretic upper limb triggered by yawning. We describe the first case of PBO in a patient with a first manifestation of tumefactive multiple sclerosis (MS). METHODS: A 35-year-old man presented to the emergency department with a first episode of generalized seizure. Neurologic examination revealed left-sided spastic hemiparesis, predominantly affecting his upper limb. Brain MRI showed a tumefactive right hemisphere lesion consistent with demyelination...

INTRODUCTION: Baló's concentric sclerosis (BCS) is a rare subtype of multiple sclerosis characterized by inflammatory demyelination within the central nervous system. CASE PRESENTATION: This case report presents a challenging diagnostic scenario involving a 26-year-old woman diagnosed with BCS. Despite treatment, her condition did not ameliorate, and magnetic resonance imaging (MRI) findings remained unchanged. A subsequent stereotactic biopsy revealed tumefactive Balo disease, highlighting the intricate diagnostic and therapeutic issues surrounding BCS...
