Lymphoplasmacyte-Rich Meningioma of the Third Ventricle: Case Report

Introduction Meningiomas are the most common primary intracranial tumors, accounting for up to 35% of the neoplasms in this category. Approximately 10­20% of these neoplasms are histologically atypical, and the lymphoplasmacyte-rich meningioma (LPM) corresponds to a very rare subtype of meningioma that is characterized histopathologically by massive infiltrates of inflammatory cells. The case described in the present study is the sixth case of an intraventricular LPM found in the literature and the first case considering the location in the third ventricle. Case Description A 21-year-old male without previous comorbidities sought medical attention due to visual impairment (complaining of intermittent visual blur) for 2 months. A magnetic resonance imaging of the brain confirmed the presence of a well-delimited solid mass in the third ventricle of 3.0 2.3 cmwith a cystic component that extended itself inferiorly and distorted the visual pathway anatomy. Neurosurgeons decided to access the lesion using an interhemispheric transcallosal approach with a transforaminal access, and the lesion was resected completely. The patient has an ambulatorial endocrinological follow-up and is neurologically stable 6 months after the procedure. No new visual deficits were noted. Conclusion Lymphoplasmacyte-rich meningioma is a very rare intracranial tumor, and the involvement of the third ventricle make this case unique.

Intracranial Subdural Hematoma after Spinal Anesthesia: Report of Two Cases with different Outcomes

Spinal anesthesia is a technique commonly used for local anesthesia and in obstetric surgeries. Rarely, the formation of an intracranial subdural hematoma (SDH) may result from spinal anesthesia, constituting a serious condition that often leads to severe neurological deficits. The presentation and course of this pathology may occur in a completely different way, which makes its diagnosis and management difficult. In the present article, the authors report two cases of patients with intracranial SDH after spinal anesthesia with completely different presentations and outcomes, demonstrating the variability of the manifestations of this condition. A quick review of key points of its pathophysiology, symptomatology, diagnosis, and treatment was also performed.

Impact of surgery on pain, disability, and quality of life of patients with degenerative lumbar disease: Brazilian data / Impacto da cirurgia na dor, incapacidade e qualidade de vida de portadores de doença degenerativa lombar: dados brasileiros

ABSTRACT Objective: To study the impact of surgery on pain, disability, quality of life, and patient satisfaction in a sample of patients with Degenerative Lumbar Disease (DLD). Methods: Retrospective analysis of prospectively collected data. Comparison between pre and postoperative (6 - 12 months) ODI and SF-36, plus postoperative Patient Satisfaction Index. Results: From a total of 216 patients included, improvement was observed in average scores of pain (201.2%), disability (39.7%), physical quality of life (42%), and mental quality of life (37.8%). Among these patients, 57.7% reached or surpassed the minimal clinically important difference (MCID) for ODI, 57.7% for the SF-36 pain component, 59.7% for the SF-36 physical component summary, and 50.5% achieved or surpassed the MCID for the SF-36 mental component summary. Conclusions: Surgery produced a significantly positive impact on pain, disability, and quality of life of patients. Overall, 82.5% of the patients were satisfied.

RESUMO Objetivo: Descrever o impacto da cirurgia na dor, incapacidade, qualidade de vida e a satisfação global do paciente numa amostra unificada de pacientes portadores de DDL. Métodos: Análise retrospectiva de dados colhidos prospectivamente em pacientes operados no período de janeiro de 2014 a março de 2017, que tivessem avaliação pré-operatória e pelo menos uma avaliação pós-operatória entre 6 e 12 meses com os questionários de ODI, SF-36 e o ISP. Resultados: Um total 216 pacientes preenchia os critérios de inclusão. Houve melhora no escore médio de dor (201,2%), incapacidade (39,7%), qualidade de vida física (42%) e mental (37,8%). Da amostra, 57,7% alcançaram o MCID de dor, 59,7% de ODI, 59,7% 50,5% de PCS e 50,5% de MCS; 82,5% dos pacientes se consideraram "Satisfeitos". Conclusões: O efeito da cirurgia foi amplamente favorável na dor, incapacidade e qualidade de vida dos pacientes portadores de DDL. Estes dados podem servir de guia para aconselhamento pré-operatório quanto às perspectivas de sucesso.

Pseudotumor Cerebri Presenting Unilateral Papilledema Associated with Iron-deficiency Anemia

Pseudotumor cerebri is a relatively common pathology that is characterized by intracranial hypertension in the absence of mass lesions. It commonly affects young and obese women, and its presentation with visual loss and bilateral papilledema is well-described in the literature. We present a case of a 44-year-old, non-obese, female patient presenting with unilateral papilledema and iron-deficiency anemia. This case emphasizes this unusual presentation and the rare association with iron deficiency.

O pseudotumor cerebral é uma patologia relativamente comum, caracterizada pela hipertensão intracraniana na ausência de lesões causando efeito de massa. Frequentemente afeta mulheres jovens e obesas, e sua apresentação, com perda do campo visual e papiledema bilateral, é bem descrita na literatura. Nós apresentamos um caso de uma paciente de 44 anos, não obesa, com papiledema unilateral e anemia ferropriva. Esse caso destaca essa apresentação incomum e a rara associação com a deficiência de ferro.
