Abstract Background COVID-19 is a pandemic disease responsible for many deaths worldwide. Many neurological manifestations have been described. We report a case of normal pressure hydrocephalus (NPH) 2 months after acute COVID19 infection, in a patient without other risk factors. Case presentation A 45-year-old male patient presented an 8-month history of progressive gait disorder and cognitive impairment after being hospitalized for SARS-CoV-2 infection. Magnetic resonance imaging (MRI) was compatible with NPH. A spinal tap test was positive and there was progressive improvement after shunting, with complete resolution of symptoms. Conclusion Other infections such as syphilis, cryptococcosis and Lyme disease have been associated with NPH. Possible mechanisms for NPH after COVID include disruption of choroid plexus cells by direct viral invasion or as a result of neuroinflammation and cytokine release and hypercoagulability leading to venous congestion and abnormalities of CSF flow. Given the significance of NPH as a cause of reversible dementia, it is important to consider the possibility of a causal association with COVID19 and understand the mechanisms behind this association.

RESUMO Objetivo Caracterizar o perfil dos quadros afásicos determinados pela hemorragia subaracnóidea aneurismática (HSA) da artéria cerebral média esquerda. Método Estudo analítico, retrospectivo, transversal, tendo como banco de dados as avaliações cognitivas de 193 pacientes do Hospital da Restauração com HSA aneurismática no período de março de 2007 a novembro de 2009. Destes, foram selecionados 26 pacientes com HSA em território da ACM-E, confirmada por angiografia digital. Os quadros afásicos foram classificados através do desempenho da linguagem dos pacientes através do Protocolo Montreal Toulose - Versão Alpha e a tarefa de fluência verbal da bateria CERAD. A pesquisa foi realizada no período de junho a agosto de 2015. Resultados Foi identificado comprometimento da linguagem e fluência verbal nos pacientes com HSA em território de ACM–E quando comparados com a população controle (50 indivíduos). Dos 26 pacientes com HSA, 11 apresentaram quadros afásicos ainda no período pré-operatório. Conclusão Os resultados da pesquisa corroboram com a literatura, mostrando que o quadro da HSA promove comprometimentos cognitivos ainda na fase pré-operatória para oclusão de aneurisma. Tendo em vista os aspectos observados, os quadros afásicos predominantes caracterizam afasia de compreensão por sequelas nas áreas cerebrais posteriores.

There are few reports in the literature of transorbital penetration brain damage. We reported a transorbital craniocerebral injury caused by a barbecue skewer in a child in the context of domestic-accident. A 7-year-old male child accidentally fell and a barbecue skewer penetrated his right orbit. The object was pulled out immediately by the boy's father. On admission, he demonstrated disproportioned right hemiparesis and Axial CT images showed no evidence of fracture of orbital wall on the right side and a small hematoma and traumatic subarachnoid hemorrhage on the left hemisphere. Surgery was not indicated, antibiotics were administered for 14 days, his neurological impairment recovered completely on seven days. On the 12th post-admission day, a CT was done which showed no hematoma. At the time of discharge, the boy was alert without any physical sequelae or complication. Children are frequently harmed during play and are mainly jeopardized by accidents at home, and it is necessary more governmental investment to objectively lowering penetrating wounds to the head in children and divulgated for general population that foreign body penetrating the intracranial cavity must be removed only during surgery.

OBJECTIVE: To present the results of cerebral aneurysms treated by endovascular technique. METHOD: Retrospective analysis of patient files of Hospital Geral de Fortaleza, Brazil. RESULTS: We report the results of 163 cerebral aneurysms treated by endovascular techniques from January 2002 to October 2005. Patients with ruptured aneurysms (87.2%), according to Hunt-Hess scale were: 33.7% HH I, 28.4% HH II, 24.1% HH III, 13.8% HH IV. The Fisher scale grade IV was the most common (39.7%). Remodeling, coil embolization, arterial occlusion and histoacryl embolization were the techniques employed. Effective occlusion was achieved in 87.7%, partial occlusion in 5.3% and non-effective occlusion in 7.0% of the patients. Glasgow outcome scale results were: 76.3% GOS 5, 5.0% GOS 4, 5.8% GOS 3, 1.4% GOS 2 and 11.5% GOS 1. CONCLUSION: Endovascular treatment seems to be feasible within Brazilian public health system, with results as good as those obtained in larger international centers.OBJETIVO: Apresentar os resultados de aneurismas tratados pela técnica endovascular. MÉTODO: Análise retrospectiva de prontuários do Hospital Geral de Fortaleza, Brasil. RESULTADOS: Apresentamos os resultados de 163 aneurismas cerebrais tratados por técnicas endovasculares de Janeiro de 2002 a Outubro de 2005. Os pacientes com aneurismas rotos (87,2%) eram, segundo a escala de Hunt-Hess: 33,7% HH1; 28.4% HH II, 24.1% HH III, 13.8% HH IV. O Grau IV da escala de Fisher foi o mais comum (39,7%). Empregaram-se as técnicas de remodeling, espiras metálicas, oclusão arterial e embolização com histoacryl. Foi obtida oclusão efetiva em 87,7%, oclusão parcial em 5,3% e oclusão não-efetiva em 7,0% dos casos. De acordo com a Glasgow outcome scale, os resultados foram: 76,3% GOS 5, 5,0% GOS 4, 5,8% GOS 3, 1,4% GOS 2 e 11,5% GOS 1. CONCLUSÃO: A aplicação de técnica endovasculares mostra-se viável na rede pública brasileira, com resultados comparáveis aos de grandes centros mundiais.

Cognitive deficits caused by subarachnoid hemorrhage (SAH) after rupture of cerebral aneurysms are common, as approximately half of patients have severe, or at least striking, declines in one or more functions of the cognitive domain. The Fisher Scale is associated with the development of vasospasm and thus with the final performance of the patient after SAH. The association of this scale with language disorders in the period preceding the treatment has not been reported yet in the literature. Associate the presence of language deficits with varying degrees of the Fisher Scale in patients with SAH in the period preceding the treatment of aneurysm, as well as compare the various degrees of this scale, identifying the Fisher Scale degrees more associated with the decline of language. The database of 185 preoperative evaluations of language was studied, through the Montreal Toulouse Protocol Alpha version and verbal fluency through CERAD battery, of patients of Hospital da Restauração with aneurysmal SAH. The data relating to the Fisher Scale, the location of the aneurysm, the age and the gender of patients were obtained through review of medical records. Patients were divided according to the Fisher Scale (Fisher I, II, III or IV) and compared with a control group of individuals considered normal. Disorders in language and verbal fluency in patients with SAH in the preoperative period were evidenced. The classification of the patients according to the Fisher Scale allowed to identify differences between the sub-groups and to conclude that patients with bulkier bleeding (Fisher III and IV) have larger declines in the analyzed functions.
