Presentamos 103 meningiomas confirmados histológicamente que se localizaban en la línea media intracraneal que fueron intervenidos quirúrgicamente en nuestro servicio. Consideramos su localización, presentación clínica, radiología, tipo de cirugía practicada y evolución posterior. La edad media de nuestra serie fueron 52 años y el 70% de nuestros pacientes eran mujeres. Predominan los meningiomas parasagitales y constituyen el 40% del total. En esta localización, el 62% se sitúan en el tercio medio. Sólo 1 paciente tenía un meningioma de línea media infratentorial a nivel de la convexidad cerebelosa.
Se discuten los resultados obtenidos en términos de morbilidad, mortalidad y secuelas psicofísicas, comparándolos a los de otras largas series en las que se incluyen meningiomas de cualquier localización intracraneal.
We present 103 histollogically confirmed meningiomas of the intracranial midline that were surgically treated in our service. We consider their localization, clinical presentation, radiological appearance, surgical procedure applied and evolution. The mean age of our group is 52 years and 70% of the patients were females. Parasagittal meningiomas predominate and constitute 40% of the whole group. In this localization 62% are situated in the parasagittal middle third. Only one patient had an infratentorial midline meningioma at the level of the cerebellar convexity.
We comment our results in terms of surgical morbidity, mortality and psychophysical outcome, comparing them with those of other large series which include meningiomas situated elsewere intracranially.
