          Abstract

          RESUMEN Introducción: los meningiomas constituyen la segunda causa de tumores cerebrales primarios, en el adulto. Representan hasta el 32 % del total de los mismos. Objetivo: describir el comportamiento del meningioma intracraneal en los pacientes investigados. Materiales y métodos: se realizó un estudio analítico, descriptivo, retrospectivo a los pacientes neurointervenidos con meningioma intracraneal, en el Servicio de Neurocirugía del Hospital Docente Universitario “Comandante Faustino Pérez Hernández”, de la provincia Matanzas. En el período comprendido entre el 1ero de enero de 2017 al 1ero de enero del 2019. Los 15 pacientes intervenidos conformaron el universo de estudio. Resultados: la media poblacional fue de 55 años. Predominó el sexo femenino en un 73,3 %. La cefalea fue la manifestación clínica más frecuente, igualmente, que los meningiomas de la convexidad cerebral. En cuanto a la topografía, la media del tamaño de la lesión fue de 4,4 cm. La variedad meningotelial (40 %) fue la que predominó. El grado II de resección fue el que más se empleó. El edema cerebral postquirúrgico predominó en un 26,6 %. La puntuación de la escala de Karnofsky al egreso fue superior que al ingreso. Conclusiones: cuanto más precoz se realice el diagnóstico clínico y tratamiento quirúrgico en los pacientes portadores de meningioma, mejor será su calidad de vida al egreso.

          ABSTRACT Introduction: meningiomas are the second cause of primary brain tumors in adults, representing up to 32 % of the total. Objective: to describe the behavior of intracranial meningioma in the studied patients. Materials and methods: a retrospective, descriptive, analytical study was conducted on neurosurgery patients with intracranial meningioma in the Neurosurgery service of the University Teaching Hospital “Comandante Faustino Pérez Hernández” of the province of Matanzas, in the period from January 1st 2017 to January 1st, 2019. The 15 patients undergoing neurosurgery were the study universe. Results: the population mean was 55 years; female sex prevailed (73.3 %). Headache was the most frequent clinical manifestation as well as meningiomas of cerebral convexity in terms of topography. The average lesion size was 4.4 cm; the meningothelial variety (40 %) was the most commonly found; grade II resection was the most used one. Post-surgical cerebral edema (26.6%) predominated. Karnofsky scale score at discharge was higher than at admission. Conclusions: the earlier the clinical diagnosis and surgical treatment are performed in patients with meningioma the better will be their quality of life at discharge.

          Metastatic Atypical and Anaplastic Meningioma: A Case Series and Review of the Literature.

          Atypical (World Health Organization grade II) and anaplastic (World Health Organization grade III) meningiomas are rare, accounting for less than 5% of all meningiomas. Histologic grading has a significant impact on prognosis, risk of recurrence, and the need for adjuvant radiation or chemotherapy. Extracranial metastases are even more infrequent and occur in 0.1% of all cases.

            Surgical management of ventral and ventrolateral foramen magnum meningiomas: report on a 64-case series and review of the literature.

            Foramen magnum meningioma poses a challenge for neurosurgeons. Prognosis has generally improved with diagnostic and surgical advances over the past two decades; however, it may ultimately depend more on the surgeon's ability to tailor the approach and interpret intraoperative risks in single cases. The series comprised 64 patients operated on for ventral and ventrolateral foramen magnum meningioma. All patients underwent preoperative magnetic resonance imaging and received surgery via the dorsolateral route, rendering the series homogeneous in neuroradiological workup and surgical treatment. Particular to this series was that the majority of patients were of advanced age (n = 29; age, >65 years), had serious functional impairment (n = 30, Karnofski score <70), and large tumors (mean diameter, 3.5 cm). Total tumor removal was achieved in 52 (81 %) patients; operative mortality was nil. Early outcome varied depending on difficulties encountered at surgery (cranial nerve position and type of involvement in particular) and type of preoperative dysfunction. Long-tract signs and cerebellar deficits improved in 74 and 77 % of cases, respectively, but only 27 % of cranial nerve deficits did so. Surgical complications most often involved the cranial nerves: cranial nerve impairment, especially of the 9th through the 12th cranial nerves, due to stretching or encasement was noted in 44 cases. At final outcome assessment, two thirds of the cranial nerve deficits cleared, and all but two patients returned to a normal productive life. One patient was reoperated on during the follow-up period. Foramen magnum meningiomas behave like clival or spinal tumors depending on their prevalent extension. A dorsolateral approach tailored to tumor position and extension and meticulous surgical technique allow for definitive control of surgical complications. Scrupulous postoperative care may prevent dysphagia, a major persistent complication of surgery. Long-term observation of indolent tumor behavior at follow-up suggests that incomplete resection may be a viable surgical treatment option.
