Intraparenchymal subependymoma: Case report and literature review

CONCLUSION: Intraparenchymal subependymoma is extremely rare tumors and literature review showed only 11 cases reported. In general, they are misdiagnosed as other tumors, so careful attention on clinical and radiological features must be taken when looking at a tumor close to the ventricular system, even though it does not have any obvious direct connection to it. Despite its benign nature, total removal must be attempted given that there are reports of recurrence, especially in partially removed tumors with high proliferation index. The role of adjuvant therapy is still limited and new treatment options are being developed as our knowledge on biological and molecular characteristics advances.PMID:33948324 | PMC:PMC8088500 | DOI:10.25259/SNI_526_2020

CONCLUSIONS: Neuro-ophthalmologic findings are mostly normal in patients with visual snow syndrome. Retinal or neurological diseases must be excluded as possible causes of visual snow. PMID: 33029971 [PubMed]

Abstract Glioblastoma multiforme (GBM) is a devastating disease without cure. It is also the most common primary brain tumor in adults. Although aggressive surgical resection is standard of care, these operations are limited by tumor infiltration of critical cortical and subcortical regions. A better understanding of how the brain can recover and reorganize function in response to GBM would provide valuable clinical data. This ability, termed neuroplasticity, is not well understood in the adult human brain. A better understanding of neuroplasticity in GBM could allow for improved extent of resection, even in areas...

Authors: Pérez Silguero D, Pérez Silguero MÁ, Pérez-Silguero Jiménez S, Encinas Pisa P Abstract The case concerns a 54-year-old woman, with a history of fibromyalgia and normal preoperative ocular and systemic study, who presented with a long-lasting disabling photophobia, after sequential bilateral cataract surgery without complications. Photophobia was accompanied by good uncorrected VA, with no pain or subjective eye discomfort, without migraine or indicators of psychic conflict. It was refractory to any prescribed treatment of the ocular surface, finally responding to oral ant...

AbstractObjectivesTo investigate the value of contrast-enhanced (CE) turbo spin echo black blood (BB) sequences for imaging of therapy-naive high-grade gliomas (HGGs).MethodsConsecutive patients with histopathologically confirmed World Health Organization (WHO) grade III or IV gliomas and no oncological treatment prior to index imaging (March 2019 to January 2020) were retrospectively included. Magnetic resonance imaging (MRI)  at 3 Tesla comprised CE BB and CE turbo field echo (TFE) sequences. The lack/presence of tumor-related contrast enhancement and satellite lesions were evaluated by two readers. Sharper delineat...

Conclusions: A 3.5 or 5 mL fluoroscopy-guided GON injection of methylene blue successfully stains the GON, TON, and suboccipital nerves. This suggests that such an injection would generate blockade of all three nerve groups, which may contribute to the efficacy of the block for CGH. A volume of 3.5 ml may be enough for the performance of a fluoroscopy-guided GON block for therapeutic purposes. PMID: 33029267 [PubMed - in process]

Conclusion: As we could not identify any other cause for the subacute subdural hematoma, hemorrhage from the meningioma was the most probable cause, and thus, we decided to remove it along with clot evacuation. Based on neuropathological findings, we propose an alternative mechanism for this spontaneous hemorrhage from the meningioma, involving the place where the periphery of the lesion insertion, the dura mater as the origin of the hemorrhage. Knowledge of this association could help define the best treatment in such cases. PMID: 33024602 [PubMed]

Authors: Sinclair G, Johnstone P, Hatiboglu MA Abstract Up until, June 13, 2020,>7,500,000 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and>400,000 deaths, across 216 countries, have been confirmed by the World Health Organization (WHO). With reference to the two previous beta-CoV outbreaks (SARS-CoV and middle east respiratory syndrome [MERS]), this paper examines the pathophysiological and clinical similarities seen across all three CoVs, with a special interest in the neuroinvasive capability and subsequent consequences for patients with primary or metastatic brain tumors. More wid...

Authors: Telles JPM, Yamaki VN, Yamashita RG, Solla DJF, Paiva WS, Teixeira MJ, Neville IS Abstract Background: Patients with cancer are subject to all neurosurgical procedures of the general population, even if they are not directly caused by the tumor or its metastases. We sought to evaluate the impact of urgent neurosurgery on the survival of patients with cancer. Methods: We included patients submitted to neurosurgeries not directly related to their tumors in a cancer center from 2009 to 2018. Primary endpoints were mortality in index hospitalization and overall survival. Results: We included 410 patien...

Conclusion: Proximal occlusion of the basilar artery combined with STA-SCA bypass was successful in preventing rerupture of BAD and ensuring blood flow in the upper basilar region. Although there is controversy regarding acute treatment for ruptured BAD, direct proximal occlusion with sufficient revascularization using bypass skull base technique may be one of the optimal treatments even in this era of endovascular treatment.
