ABSTRACT

RESUMEN En muchas ocasiones, los pacientes con tumores cerebrales tienen una variedad de síntomas psiquiátricos inespecíficos. Algunos de estos pueden constituir la primera o única manifestación del tumor, sin la presencia de ningún síntoma o signo neurológico. El diagnóstico ha de basarse en la anamnesis completa y en la exploración neurológica; la neuroimagen confirmará el diagnóstico clínico. Con el presente trabajo se describió la asociación inusual de hematoma subdural crónico y meningioma parasagital en un caso presentado. Se trató de un paciente de 68 años con antecedentes de esquizofrenia. Acudió a consulta con una hemiparesia izquierda. Se le realizó una tomografía axial computarizada de cráneo y arrojó un hematoma subdural crónico y un meningioma parasagital derecho. Se le aplicó tratamiento quirúrgico en dos tiempos operatorios. Su evolución posquirúrgica transcurrió sin complicaciones (AU).


ABSTRACT In many cases, patients with brain tumors have a variety of nonspecific psychiatric symptoms. Some of them can be the first or the only manifestation of the tumor, without presenting any neurological signs or symptoms. The diagnosis must be based on the complete anamnesis and on the neurological examination. The neuroimaging will confirm the clinical diagnosis. The unusual association of a chronic subdural hematoma and a parasagittal meningioma was described in a case presented in the current work. It dealt with a patient, aged 68 years with antecedents of schizophrenia. He assisted the consultation with left hemiparesis. A skull computed tomography showed a chronic subdural hematoma and a right parasagittal meningioma. He underwent a two-steps surgery. His post-surgery evolution ran without complications (AU).

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 (AU).


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 (AU).

ABSTRACT

Abstract Introduction: One of the main concerns in endoscopic endonasal approaches to the skull base has been the high incidence and morbidity associated with cerebrospinal fluid leaks. The introduction and routine use of vascularized flaps allowed a marked decrease in this complication followed by a great expansion in the indications and techniques used in endoscopic endonasal approaches, extending to defects from huge tumours and previously inaccessible areas of the skull base. Objective: Describe the technique of performing endoscopic double flap multi-layered reconstruction of the anterior skull base without craniotomy. Methods: Step by step description of the endoscopic double flap technique (nasoseptal and pericranial vascularized flaps and fascia lata free graft) as used and illustrated in two patients with an olfactory groove meningioma who underwent an endoscopic approach. Results: Both patients achieved a gross total resection: subsequent reconstruction of the anterior skull base was performed with the nasoseptal and pericranial flaps onlay and a fascia lata free graft inlay. Both patients showed an excellent recovery, no signs of cerebrospinal fluid leak, meningitis, flap necrosis, chronic meningeal or sinonasal inflammation or cerebral herniation having developed. Conclusion: This endoscopic double flap technique we have described is a viable, versatile and safe option for anterior skull base reconstructions, decreasing the incidence of complications in endoscopic endonasal approaches.


Resumo Introdução: Uma das principais preocupações em abordagens endoscópicas endonasais da base do crânio tem sido a alta incidência e morbidade associada a fístulas liquóricas. A introdução e o uso rotineiro de retalhos vascularizados permitiram uma acentuada redução dessa complicação, seguida por uma grande expansão nas indicações e técnicas utilizadas nas abordagens endoscópicas endonasais, incluindo grandes tumores e áreas anteriormente inacessíveis da base do crânio. Objetivo: Descrever a técnica cirúrgica realizando uma reconstrução endoscópica multicamadas da base anterior do crânio com duplo retalho, sem craniotomia. Método: Descrição passo a passo da técnica endoscópica com duplo retalho (retalhos vascularizados nasoseptal e pericraniano e enxerto livre de fascia lata), utilizados e ilustrados em dois pacientes com meningioma do sulco olfatório submetidos à cirurgia por via endoscópica endonasal. Resultados: Em ambos os pacientes procedeu-se ressecção total macroscópica seguido de reconstrução da base anterior do crânio com os retalhos nasoseptal e pericraniano onlay e enxerto livre de fáscia lata inlay. Os pacientes apresentaram uma excelente recuperação, sem sinais de fístula liquórica, meningite, necrose do retalho, inflamação meníngea crônica ou sinonasal ou hérnia cerebral. Conclusão: A técnica endoscópica de duplo retalho, como descrita, trata-se de uma opção viável, versátil e segura para as reconstruções da base anterior do crânio, diminuindo a incidência de complicações em abordagens cirúrgicas endoscópicas endonasais.

ABSTRACT

RESUMEN Se presentó un caso de una paciente de 70 años de edad, con antecedentes patológicos personales de hipertensión arterial controlada, además de un síndrome demencial instaurado hace 5 años aproximadamente. Con un diagnóstico presuntivo de una demencia tipo Alzheimer y sin estudios desde el punto de vista imagenológico. Se le realizaron diversos estudios que arrojaron una lesión extraaxial interpretada como un meningioma del tercio medio del ala del esfenoides. Se le aplicó una resección tumoral de la totalidad de la lesión, su evolución postquirúrgica fue satisfactoria.


ABSTRACT The case presented is the one of a female patient aged 70 years, with personal pathological antecedents of controlled arterial hypertension besides dementia syndrome for around five years, presumptively diagnosed as Alzheimer-kind dementia without imaging studies. She underwent several studies showing an extra axial lesion that was interpreted as meningioma of the medial third of the sphenoid wing. The tumor resection of the entire lesion was carried out; the post-surgery evaluation was satisfactory.

ABSTRACT

Los meningiomas son los tumores no gliales más comunes del sistema nervioso central constituyendo el 24%-30% de los tumores intracraneales y el 25% de los tumores de médula espinal. Se originan de células de la aracnoides y en general presentan un comportamiento benigno. Existe un subtipo llamado meningioma extracraneal primario o extradural que es poco frecuente y afecta principalmente el área de cabeza y cuello. Debido a su baja prevalencia y síntomas poco característicos son a menudo diagnosticados por fortuna, siendo la inmunohistoquímica fundamental. Se presenta el caso de una mujer adulta con una lesión tumoral en oído medio diagnosticada inicialmente mediante una biopsia incisional como un granuloma de colesterol. Luego del tratamiento quirúrgico y estudio de inmunohistoquímica se concluye el diagnóstico definitivo de meningioma extradural de oído medio. Se analiza la literatura al respecto y se discute sobre su epidemiología, clínica, estudio y manejo.


Meningiomas are the most common non-glial tumors of the central nervous system constituting 24-30% of intracranial tumors and 25% of spinal cord tumors. They originate from arachnoid cells and generally exhibit benign behavior. The subtype primary extracranial meningioma or extradural meningioma that is uncommon and affects the head and neck area. Due to their low prevalence and uncharacteristic symptoms are often diagnosed by fortune, being the immunohistochemistry fundamental. We present the case of an adult woman with a tumor lesion in the middle ear initially diagnosed by an incisional biopsy such as a cholesterol granuloma. After the surgical treatment and immunohistochemical study, the definitive diagnosis of extradural meningioma of the middle ear is concluded. The literature on this subject is analyzed and its epidemiology, clinical practice, study and management are discussed.

ABSTRACT

BACKGROUND: Tuberculum sellae meningiomas is a serious challenge for neurosurgeons. It accounts for up to 10% of all intracranial meningiomas. The difficulty in surgically excising a Tuberculum sellae meningioma comes from its anatomical relationship to the optic nerves and chiasm and to the anterior cerebral and internal carotid arteries and their perforators. The authors discuss the main approaches and the complications based on their experience in comparison to previously reported data. METHODS: We report our personal case series of 38 patients with Tuberculum sellae meningiomas; 36 patients under went craniotomy for tumor resection (12 bifrontal, 12 pterional, 6 supraciliary, 4 unilateral frontals, and 2fronto-orbito-zygomatic); in two patients, the excision was performed through an endoscopic endonasal approach. The Simpson grade of meningioma resection as wellhe non-visual morbidity and the mortality rates were analyzed. RESULTS: Thirty-one patients had Simpson grades 1 and 2 excisions, while seven had Simpson grade 4 excisions. The overall rate of non-visual morbidity was 13.15% (5 of 38 patients) and mortality was 5.3% (2 of 38). CONCLUSION: The primary symptom leading to the diagnosis of a Tuberculum sellae meningioma is visual compromise and the main goal of surgeryo achieve improvement of vision. Favorable outcomes were achieved with appropriate selection of surgical approach. More studies are necessary to define the prognostic factors for patients in this scenario.


INTRODUÇÃO: Os meningiomas de tubérculo selar certamente representam um desafio para os neurocirurgiões no que se refere ao manejo cirúrgico. Estes tumores representam até 10% de todos os meningiomas intracranianos. A dificuldade em ressecar cirurgicamente estes meningiomas provém da sua relação com os nervos ópticos, com o quiasma óptico e com as artérias carótidas internas, cerebrais anteriores e suas perfurantes. Discutimos as principais abordagens e as complicações com base em nossa série de pacientes e numa revisão da literatura. CASUÍSTICA E MÉTODOS: Relatamos nossa série de casos pessoais de 38 pacientes com meningiomas de tubérculo selar. Trinta e seis pacientes foram submetidos a craniotomia para ressecção tumoral (12 bifrontal, 12 pterional, 6 supraciliar, 4 unilateral frontal e 2 fronto-orbito-zigomático) e 2 receberam abordagem endoscópica endonasal. A escala de Simpson, bem comoaxas de morbidade e mortalidade foram analisadas durante o período pós-operatório, em função das diferentes abordagens. RESULTADOS: Trinta e um pacientes foram submetidos a excisões de grau I e II da escala de Simpson; os demais foram submetidos a excisão de grau IV da mesma escala. A taxa global de morbidade sem acometimento visual foi de 13,15% (5 de 38 pacientes), enquanto a mortalidade evidenciada foi de 5,3% (2 dentre 38 pacientes). CONCLUSÃO: O principal sintoma que leva ao diagnóstico de meningioma de tubérculo selar é o comprometimento visual, de modo que o principal objetivo da cirurgia é alcançar a melhora da visão nestes pacientes. Os resultados alcançados foram favoráveis quando associados com a seleção apropriada da abordagem cirúrgica. Mais estudos são necessários para definir os fatores prognósticos para os pacientes com meningioma de tubérculo selar após intervenção cirúrgica.

ABSTRACT

A pesar del desarrollo de las técnicas quirúrgicas de base de cráneo, los meningiomas petroclivales constituyen un reto para el neurocirujano debido a su localización y relación con estructuras neurológicas y vasculares críticas. Se reportan 2 pacientes con diagnóstico de meningioma petroclival que recibieron tratamiento por etapas incluyendo derivación ventrículo peritoneal asistida por endoscopia para la hidrocefalia, abordaje endonasal endoscópico (AEE) extendido al ápex petroso, keyhole subtemporal y retromastoideo con remoción de la lesión. La evolución fue satisfactoria. Se concluyó que los abordajes endoscópicos y por etapas constituyen una excelente opción en el tratamiento de los meningiomas petroclivales.


In spite of the development of the skull base surgery techniques, petroclival meningiomas are a challenge for neurosurgeon due to their localization and relationship with neurovascular structures. Those are two patient with diagnostic of petroclival meningioma whom received treatment step by step included ventricle peritoneal shunt with endoscopic guide for hydrocephalus, extended endonasal approach to petrous apex, subtemporal and retrosigmoid keyhole. The endoscopic approach is an excellent option in the treatment of petroclival meningioma.

ABSTRACT

ABSTRACT CONTEXT: Brain metastases are the most common tumors of the central nervous system. Because of their high frequency, they may be associated with rare situations. Among these are tumor-to-tumor metastasis and an even a rarer situation called simultaneous brain tumors, which are more related to primary tumors of the reproductive and endocrine systems. CASE REPORT: A 56-year-old male patient with a history of renal cell carcinoma (which had previously been resected) presented with a ventricular lesion (suggestive of metastatic origin) and simultaneous olfactory groove lesion (probably a meningioma). First, only the ventricular lesion was dealt with, but after a year, the meningothelial lesion increased and an occipital lesion appeared. Therefore, both of these were resected in a single operation. All the procedures were performed by the same neurosurgeon. The patient evolved without neurological deficits during the postoperative period. After these two interventions, the patient remained well and was referred for adjuvant treatment. CONCLUSIONS: This study provides the first description of an association between these two tumors. Brain metastases may be associated with several lesions, and rare presentations such as simultaneity with meningioma should alert neurosurgeons to provide the best oncological treatment.


RESUMO CONTEXTO: As metástases cerebrais são os tumores mais comuns do sistema nervoso central e, devido à sua elevada frequência, podem estar associadas a situações raras. Entre estas estão as "tumor to tumor metastasis" e uma situação ainda mais rara chamada de tumores cerebrais simultâneos, mais relacionados a tumores primários dos sistemas endocrinológico e reprodutivo. RELATO DE CASO: Um homem de 56 anos com histórico de câncer de células renais (extirpado previamente) apresentou-se com lesão ventricular (sugestiva de origem metastática) e simultaneamente com uma lesão em topografia de goteira olfatória (provavelmente meningioma). Primeiramente, apenas a lesão ventricular foi abordada, porém após um ano, a lesão meningotelial aumentou e uma lesão occipital apareceu e então ambas foram ressecadas em uma única cirurgia. Todos os procedimentos foram realizados pelo mesmo neurocirurgião. O paciente evoluiu sem déficits neurológicos no período pós-operatório. Após essas duas intervenções, o paciente permaneceu bem, sendo encaminhado para tratamento adjuvante. CONCLUSÕES: O presente trabalho é a primeira descrição da associação encontrada entre esses dois tumores. As metástases cerebrais podem associar-se a várias lesões, e manifestações raras, tais como apresentação simultânea com meningioma, devem alertar o neurocirurgião a fornecer o melhor tratamento oncológico.

ABSTRACT

Abstract Introduction: The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity) and the subarachnoid space (sterile area), reducing the high risk of contamination. Objective: To assess the otorhinolaryngologic complications in patients undergoing endoscopic surgery of the skull base, in which a nasoseptal flap was used. Methods: This was a retrospective study that included patients who underwent endoscopic skull base surgery with creation of a nasoseptal flap, assessing for the presence of the following post-surgical complications: cerebrospinal fluid leak, meningitis, mucocele formation, nasal synechia, septal perforation (prior to posterior septectomy), internal nasal valve failure, epistaxis, and olfactory alterations. Results: The study assessed 41 patients undergoing surgery. Of these, 35 had pituitary adenomas (macro- or micro-adenomas; sellar and suprasellar extension), three had meningiomas (two tuberculum sellae and one olfactory groove), two had craniopharyngiomas, and one had an intracranial abscess. The complications were cerebrospinal fluid leak (three patients; 7.3%), meningitis (three patients; 7.3%), nasal fossa synechia (eight patients; 19.5%), internal nasal valve failure (six patients; 14.6%), and complaints of worsening of the sense of smell (16 patients; 39%). The olfactory test showed anosmia or hyposmia in ten patients (24.3%). No patient had mucocele, epistaxis, or septal perforation. Conclusion: The use of the nasoseptal flap has revolutionized endoscopic skull base surgery, making the procedures more effective and with lower morbidity compared to the traditional route. However, although mainly transient nasal morbidities were observed, in some cases, permanent hyposmia and anosmia resulted. An improvement in this technique is therefore necessary to provide a better quality of life for the patient, reducing potential complications.


Resumo Introdução: O grande crescimento no número de cirurgias endoscópicas transnasais para a base do crânio ocorreu a partir de um maior conhecimento anatômico da região; do desenvolvimento de materiais e instrumentais específicos e, principalmente, após o uso do retalho nasosseptal como uma barreira entre o trato sinusal (cavidade contaminada) e o espaço subaracnóideo (área estéril), com redução de grandes riscos de contaminação. Objetivo: Avaliar as complicações otorrinolaringológicas nos pacientes submetidos à cirurgia endoscópica da base do crânio, na qual foi usado o retalho nasoseptal. Método: Estudo retrospectivo, no qual foram avaliados os pacientes submetidos à cirurgia da base do crânio por via endoscópica com retalho nasosseptal, quanto à presença no pós-operatório das seguintes complicações: fístula liquórica, meningite, formação de mucocele, sinéquia nasal, perfuração septal (anterior à septectomia posterior), insuficiência de válvula nasal interna, epistaxe e alteração olfatória. Resultados: Foram avaliados 41 pacientes submetidos à cirurgia. Desses, 35 eram portadores de adenomas hipofisários (macro ou microadenomas; selares e extensão supraselar), três meningiomas (dois de tubérculo selar e um da goteira olfatória), dois craniofaringiomas e um abscesso intracraniano. As complicações observadas foram: fístula liquórica (três pacientes - 7,3%), meningite (três pacientes - 7,3%), sinéquia em fossa nasal (oito pacientes - 19,5%), insuficiência de válvula nasal interna (seis pacientes - 14,6%) e queixa de pioria do olfato (16 pacientes - 39%). O teste olfatório evidenciou anosmia ou hiposmia em 10 pacientes (24,3%). Nenhum paciente apresentou mucocele, epistaxe ou perfuração septal. Conclusão: O uso do retalho nasosseptal proporcionou uma revolução na cirurgia da base do crânio por via endoscópica e tornou os procedimentos mais eficazes e com baixa morbidade, comparado com a via tradicional. Porém, passou a ocasionar morbidades nasais principalmente transitórias, mas em alguns casos permanentes, como hiposmia e anosmia. Assim, torna-se necessário um aperfeiçoamento dessa técnica para proporcionar uma melhoria na qualidade de vida do paciente e diminuir possíveis complicações.

ABSTRACT

Los meningiomas del surco olfatorio representan el 10 por ciento de los meningiomas intracraneales, se originan de la lámina cribosa del etmoides, la sutura fronto-esfenoidal y el plano esfenoidal. Son tumores en su mayoría benignos y potencialmente curables, la recurrencia ocurre en grado variable siendo el grado de resección quirúrgica el predictor más importante de recurrencia. En este artículo se exponen los resultados alcanzados con el abordaje endonasal endoscópico extendido transcribiforme en pacientes con meningiomas del surco olfatorio en el servicio de neurocirugía del hospital clínico quirúrgico Hermanos Ameijeiras. La serie fue de 12 pacientes donde la cefalea, la anosmia y los trastornos neuropsicológicos fueron los síntomas predominantes. Los tumores tuvieron un tamaño ≥ a 6 cm en el 50 por ciento de los casos y con el abordaje endonasal endoscópico extendido transcribiforme se alcanzó una resección total con Simpson I en el 92 por ciento de los enfermos. Los límites del abordaje endonasal endoscópico en la fosa anterior se encuentran en constante extensión, siendo el abordaje endonasal endoscópico extendido transcribiforme la opción ideal y prometedora para los pacientes con Meningiomas del surco olfatorio.


Olfactory groove meningiomas represent 10 percent of intracranial meningiomas, originate from cribriform plate of ethmoid, frontal and sphenoid suture and the sphenoid plane. They are mostly benign and potentially curable tumors, the recurrence occurs in varying degree and the extent of surgical resection is the most important predictor of this recurrence. This article presents the results achieved with the transcribiform extended endoscopic endonasal approach in patients with meningiomas of olfactorygroove in neurosurgery department of the “Hermanos Ameijeiras” hospital. The series was of 12 patients where headache, anosmia, and neuropsychological disorders were the predominant symptoms. The tumors had a size ≥ 6 cm on 50 percent of the cases and with transcribiform extended endoscopic endonasal approach was reached total removal in 92 percent (Simpson I) of the patients. The limits of endoscopic endonasal approach for anterior fossa are in constant expansion, being the transcribiform extended endoscopic endonasal approach the ideal and promising option for patients with olfactory groove meningiomas.

ABSTRACT

ABSTRACT Objective To describe a unique operative strategy, instead the classical pterional approach, and to analyses it safety and effectiveness for removal of anterior cranial fossa meningiomas. Method We identify 38 patients with tuberculum sellae and olphactory groove meningiomas operated between 1986 and 2013. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed and analyzed retrospectively. The pterional craniotomy is extended toward the frontal bone providing access through the subfrontal route, besides the usual anterolateral view provided by the classical pterional approach. Results Surgical mortality occurred in one patient (2.6%). Gross total resection was achieved in 27 patients (86.8%). Median time of follow-up was 69.4 months. Conclusion The extended pterional approach allows excellent results. Total removal of meningiomas of the anterior cranial fossa was obtained in 86.8 % of patients, with low morbidity and mortality.


RESUMO Objetivo Descrever a craniotomia pterional estendida, ao invés da abordagem pterional clássica, e analisar sua segurança e eficácia para a remoção dos meningiomas da fossa anterior. Método Identificamos 38 pacientes com meningiomas do tubérculo da sela e da goteira olfatória operados entre 1986 e 2013. Os prontuários, relatórios cirúrgicos, exames de imagem e acompanhamento pós-operatório foram analisados retrospectivamente. A craniotomia pterional com extensão para o osso frontal permite acesso pela via subfrontal além da via anterolateral do acesso pterional clássico. Resultados A mortalidade cirúrgica foi de 2,6% (um paciente). A remoção total foi alcançada em 86,8% (27 pacientes) com um tempo médio de seguimento de 69,4 meses. Conclusão A abordagem pterional estendida permite excelentes resultados. A remoção total dos meningiomas da fossa craniana anterior foi obtida em 86,8% dos pacientes, com baixa morbi-mortalidade.

ABSTRACT

Atypical/anaplastic (World Health Organization (WHO) grades II and III) are less common and have poorer outcomes than benign meningiomas. This study aimed to analyze the outcome of patients with these tumors.Method Overall/recurrence-free survivals (RFS) and the Karnofsky Performance Scale of 52 patients with grades II (42) and III (9) meningiomas surgically treated were analyzed (uni/multivariate analysis).Results Total/subtotal resections were 60.8%/35.3%. Patients <60 years-old and grade II tumors had longer survival. Grade II tumors, total resection andde novo meningioma had better RFS (univariate analysis). Patients >60 years-old, de novo meningioma and radiotherapy had longer survival and patients <60 years-old and with grade II tumors had longer RFS (multivariate analysis). Recurrence rate was 51% (39.2% Grade II and 66.7% Grade III). Operative mortality was 1.9%.Conclusion Age <60 years-old, grade II tumors and de novomeningiomas were the main predictors for better prognosis among patients with grades II and III meningiomas.


Meningiomas atipicos/anaplásticos (graus II e III da World Health Organization (WHO)) são menos comuns e tem prognóstico pior que os benignos. Este estudo visa analisar o prognóstico de pacientes com estes tumores.Método Sobrevida/sobrevida livre de doença (SLD) e índice de Karnofsky de 52 pacientes com meningiomas graus II (42) e III (9) tratados cirurgicamente foram avaliados (análises uni/multivariada).Resultados Pacientes <60 anos e com tumores grau II tiveram sobrevida mais longa. Tumores grau II , ressecção total e meningioma de novotiveram melhor SLD (análise univariada). Pacientes >60 anos, meningiomade novo e radioterapia tiveram sobrevida mais longa e, pacientes <60 anos e com tumores grau II tiveram SLD mais longa (análise multivariada). Recidiva ocorreu em 51% (39.2% Graus II e 66,7% Graus III). A mortalidade operatória foi 1,9%.Conclusão Idade <60 anos, meningiomas grau II e de novo foram preditores de melhor prognóstico entre pacientes com meningiomas graus II/ III.

ABSTRACT

Objective: To analyze the clinical outcome of patients with foramen magnum (FM) meningiomas. Method: Thirteen patients (11 Feminine / 2 Masculine with FM meningiomas operated on through lateral suboccipital approach were studied. Clinical outcome were analyzed using survival (SC) and recurrence-free survival curves (RFSC). Results: All tumors were World Health Organization grade I. Total, subtotal and partial resections were acchieved in 69.2%, 23.1% and 7.7%, respectively, and SC was better for males and RFSC for females. Tumor location, extent of resection and involvement of vertebral artery/lower cranial nerves did not influence SC and RFSC. Recurrence rate was 7.7%. Operative mortality was 0. Main complications were transient (38.5%) and permanent (7.7%) lower cranial nerve deficits, cerebrospinal fluid fistula (30.8%), and transient and permanent respiratory difficulties in 7.7% each. Conclusions: FM meningiomas can be adequately treated in public hospitals in developing countries if a multidisciplinary team is available for managing postoperative lower cranial nerve deficits. .


Objetivo: Analisar as evoluções clínicas de 13 pacientes com meningiomas do forame magno (FM). Método: Foram estudados 13 pacientes com meningiomas do FM (11 Feminino / 2 Masculino) operados por abordagem suboccipital lateral. As evoluções clínicas foram analisadas usando curvas de sobrevida (SC) e de sobrevida livre de doença (RFSC). Resultados: Os 13 tumores eram Grau I da Organização Mundial de Saúde. Ressecções total, subtotal and parcial foram obtidas em 69,2%, 23,1 e 7,7%, respectivamente. A SC foi melhor para homens e a RFSC foi melhor para mulheres. Localização/ extensão da ressecção/envolvimento da artéria vertebral/nervos cranianos baixos não influenciaram a SC/RFSC. A taxa de recorrência foi 7,7%. A mortalidade operatória foi zero. As principais complicações foram déficits de nervos cranianos baixos transitórios (38,5%) e permanentes (7,7%); fístula de líquido cefalorraquidiano (30,8%) e dificuldades respiratórias transitórias e permanentes em 7,7% cada. Conclusões: Meningiomas do FM podem ser adequadamente tratados em hospitais públicos em países em desenvolvimento se houver uma equipe multidisciplinar para cuidar de déficits de nervos cranianos baixos pós-operatórios. .
