Brain metastases are rare and poorly understood complications of oesophageal carcinoma. This report describes a case of brain metastasis as the initial presentation of oesophageal adenocarcinoma. The rarity and the lack of prospective clinical trials of brain metastasis in oesophageal cancer result in the absence of treatment guidelines. Common treatments for brain metastases, regardless of tumour of origin, are applicable to oesophageal brain metastases and include surgical resection, whole brain radiation therapy, stereotactic radiosurgery, chemotherapy/immunotherapy and/or symptomatic control with steroids and anticonvulsants., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2025.

Introduction: COVID-19 challenges have underscored the potential of telemedicine in migraine management. This study focuses on assessing patients' telemedicine experience for headache management in Lithuania and identifying key barriers and facilitators for its wider use., Methods: A nationwide e-survey was conducted in 2023 via the Lithuanian Association of Migraine Patients' website, social media platforms, websites of public and private healthcare facilities, and migraine self-help groups. The survey covered sociodemographics, migraine characteristics, previous experience with teleconsultations for headaches with neurologists and general practitioners (GP), perceived advantages and disadvantages of telehealth, and preferred future consultation types., Results: Eight hundred and forty seven respondents with a confirmed migraine diagnosis were analyzed. The majority were female (97.2%), with a median age of 35 (IQR 30-42) years and an average of 5 (IQR 3-9) monthly headache days (MHDs). 7.0% of respondents had chronic migraine (CM). Prior teleconsultations for headaches were reported by 35.2% of respondents, 26.2% with a GP and 17.0% with a neurologist ( p < 0.0001). Teleconsultation outcomes included continuation of a prescribed treatment (84.7% for GPs and 83.3% for neurologists, p = 0.7295), initiation of new acute medications (12.2% for GPs with 70.4% reported as effective and 27.1% for neurologists with 84.6% effective, p = 0.0005 and p < 0.0001, respectively). Reasons for not undergoing remote neurology consultations: the lack of inquiry (69.7%), unavailability from neurologists (18.1%) and respondent's opposition to remote consultations (12.2%). Patients evaluated their experience with remote neurology services better than that of GPs ( p = 0.0289). 67.3% of respondents preferred a mixed-mode approach for future consultations. In-person-only preference (29.0%) correlated with multiple factors, including history of remote primary neurology consultations (OR 5.89, p = 0.0022), lower education (OR 2.20, p = 0.0001), physically demanding work (OR 1.95, p = 0.0001), and number of drawbacks in telemedicine identified (OR 1.30, p < 0.0001), and worse experience of a prior remote GP consultation (OR 0.704, p < 0.0001). The main indicator of preference for remote-only consultations was the perception of fewer telemedicine disadvantages (OR 0.503, p = 0.0007)., Conclusions: Our findings confirm that telemedicine contributes to effective migraine management and is used limitedly in Lithuania. Despite one-third of respondents having experienced teleconsultations, significant barriers remain. Our study highlights a clear preference for a hybrid consultation type., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Andruskevicius, Petrosian, Dapkute, Jokubaitis and Ryliskiene.)

Detection of neuronal antibodies for autoimmune encephalitis and paraneoplastic neurological syndromes relies on commercially available cell-based assays and lineblots. However, lineblots may reveal the presence of neuronal antibodies in patients with various non-autoimmune etiologies. Herein we describe patients with non-autoimmune etiologies (cohort B) and detectable neuronal antibodies and compare them to definite cases of autoimmune encephalitis (cohort A) for differences in clinical data. All patients positive for at least one neuronal antibody were retrospectively evaluated for autoimmune encephalitis and/or paraneoplastic neurological syndrome between 2016 and 2022. 39 cases in cohort B and 23 in cohort A were identified. In cohort B, most common diagnoses were neurodegenerative disorders in 9/39 (23.1%), brain tumors in 6/39 (15.4%) while most common detected antibodies were anti-titin (N10), anti-recoverin (N11), anti-Yo (N8) and all were detected in serum only. Differential aspects between cohort A and B were CSF pleocytosis (14/23 (60.8%) vs 11/35 (31.4%), p = 0.042, respectively), MRI features suggestive of encephalitis (6/23 (26.1%) vs 0 (0%), p = 0.002, respectively) and epilepsy restricted to temporal lobes (14/23 (60.9%) vs 2/30 (6.7%), p = 0.0003, respectively). A large proportion of lineblot results were non-specific when only serum was tested and were frequently found in non-autoimmune neurological conditions., (© 2024.

Background: tumefactive multiple sclerosis (TmMS) is a rare subtype of a demyelinating disease that develops over time. Cases of hyperacute presentations mimicking cerebrovascular disorders have been reported; however, detailed clinical and demographic data are lacking., Methods: this study aimed to systematically review the literature on tumefactive demyelinating disorders presenting as strokes. After screening the PubMed, PubMed Central, and Web of Science databases, 39 articles describing 41 patients were identified, including 2 historical patients from our center., Results: 23 (53.4%) patients were diagnosed with multiple sclerosis variants (vMS), 17 (39.5%) with inflammatory demyelinating variants (vInf), and 3 with tumors; however, only 43.5% of cases were verified histologically. In subgroup analysis, vMS differed from vInf in several aspects. Inflammatory cerebral spinal fluid parameters, including pleocytosis, proteinorachia was more commonly observed in vInf [11 (64.7%) vs. 1 (5.2%), P = 0.001 and 13/17 (76.4%) vs. 6/23 (31.5%), P = 0.02] than that in vMS. Neurological deterioration and fatal outcomes were more commonly observed in vInf [13/17 (76.4%) vs. 7/23 (30.4%), P = 0.003, and 11/17 (64.7%) vs. 0/23 (0%), P = 0.0001] than that in vMS., Conclusions: Clinicodemographic data might aid in recognizing different subtypes of TmMS and warrant consideration of unconventional therapies because outcomes may be poor in the vInf of TmMS., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited progressive cerebral microangiopathy with considerable phenotypic variability. The purpose of this study was to describe the generalizability of a recently proposed grading system of CADASIL across multiple centers in the United States., Methods: Electronic medical records (EMR) of an initial neurological assessment of adult patients with confirmed CADASIL were reviewed across 5 tertiary referral medical centers with expertise in CADASIL. Demographic, vascular risk factors, and neuroimaging data were abstracted from EMR. Patients were categorized into groups according to the proposed CADASIL grading system: Grade 0 (asymptomatic), Grade 1 (migraine only), Grade 2 (stroke, TIA, or MCI), Grade 3 (gait assistance or dementia), and Grade 4 (bedbound or end-stage). Inter-rater reliability (IRR) of grading was tested in a subset of cases., Results: We identified 138 patients with a mean age of 50.9 ± 13.1 years, and 57.2% were female. The IRR was acceptable over 33 cases (κ=0.855, SD 0.078, p <0.001) with 81.8% being concordant. There were 15 patients (10.9%) with Grade 0, 50 (36.2%) with Grade 1, 61 (44.2%) with Grade 2, 12 (8.7%) with Grade 3, and none with Grade 4. Patients with a lower severity grade (grade 0 vs 3) tended to be younger (49.5 vs. 61.9 years) and had a lower prevalence of hypertension (50% vs. 20%, p  = 0.027) and diabetes mellitus (0% vs. 25%, p  = 0.018). A higher severity grade was associated with an increased number of vascular risk factors ( p  = 0.02) and independently associated with hypertension and diabetes ( p <0.05). Comparing Grade 0 vs. 3, cortical thickness tended to be greater (2.06 vs. 1.87 mm; p  = 0.06) and white matter hyperintensity volume tended to be lower (54.7 vs. 72.5 ml; p  = 0.73), but the differences did not reach significance., Conclusion: The CADASIL severity grading system is a pragmatic, reliable system for characterizing CADASIL phenotype that does not require testing beyond that done in standard clinical practice. Higher severity grades tended to have a higher vascular risk factor burden. This system offers a simple method of categorizing CADASIL patients which may help to describe populations in observational and interventional studies., Competing Interests: None., (© 2023 The Author(s).)

Background: Spontaneous thrombosis of a developmental venous abnormality (DVA) is a rare complication associated with hypercoagulability. The objective of this case report is to describe an association between DVA thrombosis and mild coronavirus disease 2019 (COVID-19) infection in a vaccinated patient., Observations: A 28-year-old male with hypertension presented with severe headache and left-sided hemiparesis. Five weeks prior to presentation, the patient experienced mild respiratory symptoms and tested positive for COVID-19. Admission brain computed tomography (CT) showed a large right parieto-occipital intracerebral hemorrhage with surrounding edema. CT venography and catheter angiography showed a thrombosed DVA with associated venous infarction as the hemorrhage etiology. He was treated with decompressive hemicraniectomy, external ventricular drain placement, and systemic anticoagulation. The patient was functionally independent (modified Rankin Scale score, 2) at 4-month follow-up. Hypercoagulability work-up was unremarkable., Lessons: Delayed DVA thrombosis after the COVID-19 infectious period may represent an association between the infection and a protracted systemic viral-induced hypercoagulable state. The severity of COVID-19 symptomatology does not appear to correlate with risk of DVA thrombosis. Young patients with a recent history of COVID-19 infection who present with venous infarction should be evaluated for an underlying thrombosed DVA.
