MRI of the brain demonstrated symmetric expansile T2 FLAIR hyperintensities within the bilateral mesial temporal lobes, thalami, and cingulate gyri (Figure 1). Due to the symmetry of the signal changes in the bilateral cerebral hemispheres and especially the mesial temporal lobes, an autoimmune encephalitis was strongly favored on imaging. Glioblastoma was a consideration on the initial scan; however, it was thought to be much less likely, and the patient received immunosuppression with plasmapheresis and IV steroids. At that time, it was even presumed that the patient improved mildly with plasmapheresis. The patient was discharged on PO steroids; however, a few weeks later the patient presented in status epilepticus. On repeat MRI brain, findings were not significantly changed, and the diagnosis of an autoimmune process was again favored on imaging. The patient received plasmapheresis and IV steroids. However, on the second admission the patient's neurologic function was markedly below baseline per the family's report. The patient had received an extensive autoimmune, infectious and metabolic work up, including testing for Creutzfeldt-Jacob disease, with all the tests coming back negative. Therefore, a brain biopsy was performed to understand the underlying pathology, IDH wild-type glioblastoma. On MRI, the expansile signal changes were bilateral and multifocal, affecting more than three cerebral lobes. This is a case of gliomatosis cerebri, which was misdiagnosed as autoimmune encephalitis due to the symmetry of cerebral involvement.","PeriodicalId":46355,"journal":{"name":"Neurohospitalist","volume":" ","pages":"19418744251343174"},"PeriodicalIF":0.9,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12102076/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144143994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to determine the prevalence, predictors, and 90-day outcomes of END in Tunisian stroke patients.Materials and methods: This was a retrospective cohort study of consecutive stroke cases admitted at the Neurology Department of the University Hospital in Monastir over 5 years, from 2018 to 2022. We included patients with an increment of two or more points on the NIHSS score within the first 7 days following IS. Univariate analysis and binary logistic regression were performed to identify independent factors associated with END.Results: We included 489 patients with a mean age of 64 years (24 to 90) and a male predominance (sex ratio M/F = 1.86). The prevalence of END was 12.06% (59/489 patients). An elevated initial NIHSS score (OR = 1.13; 95% CI = 1.05-1.21), anterior choroidal artery stroke (OR = 5.39; 95% CI = 1.99-14.55), and large artery atherosclerosis (OR = 2.85; 95% CI = 1.17-6.9), were found to be independent factors associated with END. The causes of END included IS recurrence (12%), hemorrhagic transformation (10%), brain edema (10%), and stroke progression (68%). At 90 days, 80.8% (P < 0.001) of patients who experienced END had a mRS score of 2 or more, with a mortality rate of 18.6% (P < 0.001).Conclusion: Patients with elevated NIHSS scores, AChA strokes, or LAA, should be prioritized for close observation during the acute phase. Enhancing our understanding of the predictive factors of END following IS could help target patients at very high risk of END and facilitate the development of more effective and rigorous strategies for prevention and treatment.","PeriodicalId":46355,"journal":{"name":"Neurohospitalist","volume":" ","pages":"19418744251341922"},"PeriodicalIF":0.9,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12078254/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aim to compare the incidence and timing of complications during the year under the targeted approach compared to prior years when the standard of care was followed.Methods: We conducted a single-center retrospective cohort study. We analyzed data from stroke patients treated with thrombolysis and/or endovascular thrombectomy in 2019 (pre-COVID-19, standard of care), 2020 (during COVID-19, standard of care) and 2021 (during COVID-19, targeted protocol).

This case describes a patient who demonstrated ocular dipping: slow conjugate downward eye movements with a quick return to primary gaze. Ocular dipping is a rare phenomenon that was initially described in patients with hypoxic brain injury and has since been described in only a handful of cases. Dipping resides in a spectrum of spontaneous vertical eye movements, with ocular bobbing being the first of these described eye movements. Ocular bobbing is characterized by a fast downward movement followed by a slow return to the mid gaze position which is classically associated with pontine injury. Other vertical eye movements that can be seen in patients with a disorder of consciousness include other variations of ocular bobbing and dipping, vertical myoclonus, and small-amplitude mainly vertical movements.","PeriodicalId":46355,"journal":{"name":"Neurohospitalist","volume":" ","pages":"19418744251331649"},"PeriodicalIF":0.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12050979/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
