Resumo

Introdução: os meningiomas angiomatosos (AM) são um subtipo incomum de tumores cerebrais benignos, que afetam principalmente mulheres. Este estudo investiga as características clínicas e epidemiológicas da MA e fornece uma revisão da literatura. Objetivo: analisar as características clínicas e epidemiológicas da AM, avaliar sua incidência e revisar a literatura existente. Métodos: foi realizado um estudo retrospetivo em 28 casos de AM de 584 pacientes com meningioma operados entre 2013 e 2023. Os dados foram coletados de prontuários e exames de imagem. Resultados: a AM representou 4,7% dos casos, com predominância do sexo feminino (1,8:1). As localizações tumorais comuns incluíram a convexidade (33%), a região falx/parasagital (17%) e a asa esfenoidal (17%). As apresentações clínicas foram relacionadas ao aumento da pressão intracraniana, muitas vezes apresentando sintomas inespecíficos, como cefaleia e náuseas. Os resultados da RM foram consistentes com os padrões conhecidos. Conclusão: este estudo fornece informações valiosas sobre os aspectos clínicos e epidemiológicos da AM, auxiliando no diagnóstico preciso e no cuidado ao paciente. A revisão da literatura ressalta as características únicas da AM, enfatizando a necessidade de um manejo especial.

Abstract

 Introduction: angiomatous meningiomas (AM) are an uncommon subtype of benign brain tumors, primarily affecting women. This study investigates the clinical and epidemiological features of AM and provides a literature review. Objective: to analyze the clinical and epidemiological characteristics of AM, assess its incidence, and review the existing literature. Methods: a retrospective study was conducted on 28 AM cases out of 584 meningioma patients who underwent surgery between 2013 and 2023. Data was collected from medical records and imaging exams. Results: AM comprised 4.7% of the cases, with female predominance (1.8:1). Common tumor locations included the convexity (33%), falx/parasagittal region (17%), and sphenoid wing (17%). Clinical presentations were related to increased intracranial pressure, often presenting with non-specific symptoms such as headache and nausea. MRI findings were consistent with known patterns. Conclusion: this study provides valuable insights into AM’s clinical and epidemiological aspects, aiding in accurate diagnosis and patient care. The literature review underscores the unique features of AM, emphasizing the need for special management.
