Abstract

Meningiomas are tumors that originate in the arachnoid villi and are the most common non-glial neoplasm in the central nervous system. The clinical manifestations associated with meningioma depend, fundamentally, on its location. The location in the cerebral convexity is the most frequent, especially in the frontal lobes, manifesting with headache, motor disturbances, seizures and even neurocognitive disorders. There are 15 histologic subtypes of meningioma and three histologic grades. Within these, grades two and three have a worse prognosis and a higher rate of recurrence, as well as a radiological behavior that is generally more aggressive. Although there are some imaging features that can suggest a specific subtype, the definitive diagnosis will always require histological/molecular confirmation.

Resumen

Los meningiomas son tumores que se originan en las vellosidades aracnoideas y que constituyen la neoplasia no glial más común en el sistema nervioso central. Las manifestaciones clínicas asociadas al meningioma dependen, fundamentalmente, de su localización. La ubicación en la convexidad cerebral es las más frecuente, especialmente en lóbulos frontales, manifestándose con cefalea, alteraciones motoras, convulsiones e, incluso, con trastornos neurocognitivos. Existen 15 subtipos histológicos de meningioma y tres grados histológicos. Dentro de estos, los grados dos y tres tienen un peor pronóstico y una mayor tasa de recurrencia, así como un comportamiento radiológico, por lo general, más agresivo. Aunque existen algunas características de imagen que pueden permitir sugerir un subtipo concreto, el diagnóstico definitivo siempre requerirá la confirmación histológica/molecular.
