RESUMO
PURPOSE: We conducted a National Cancer Database (NCDB) study to investigate the epidemiological characteristics and identify predictors of outcomes associated with geriatric meningiomas. METHODS: The NCDB was queried for adults aged 60-89 years diagnosed between 2010 and 2017 with grade 2 and 3 meningiomas. The patients were classified into three age groups based on their age: 60-69 (hexagenarians), 70-79 (septuagenarians), and 80-89 (octogenarians). The log-rank test was utilized to compare the differences in overall survival (OS). Univariate and multivariate Cox proportional hazards regressions were used to evaluate the mortality risk associated with various patient and disease parameters. RESULTS: A total of 6585 patients were identified. Hexagenerians were the most common age group (49.8%), with the majority of meningiomas being classified as grade 2 (89.5%). The incidence of high-grade meningiomas increased in all age groups during the study period. Advanced age, male sex, black race, lower socioeconomic status, Charlson-Deyo score ≥ 2, and higher tumor grade were independent factors of poor survival. Among the modes of treatment, the extent of surgical resection, adjuvant radiotherapy, and treatment at a noncommunity cancer program were linked with better outcomes. CONCLUSION: In geriatric patients with high-grade meningiomas, the greater extent of surgical resection and radiotherapy are associated with improved survival. However, the management and outcome of geriatric patients with higher-grade meningiomas are also associated with several socioeconomic factors.

This case report highlights the diagnostic and therapeutic journey of a 16-year-old female presenting with chronic headaches, ultimately diagnosed with anaplastic meningioma. Despite its rarity in pediatric patients, anaplastic meningioma necessitates swift recognition and management due to its aggressive nature. Imaging findings, including CT and MRI, initially suggested a provisional diagnosis of hemangiopericytoma, emphasizing the diagnostic challenge posed by this condition. Surgical intervention revealed unexpected histopathological findings, highlighting the importance of thorough evaluation. Treatment involved frontal craniectomy and excision followed by adjuvant radiotherapy. While the patient's postoperative course was uneventful, histopathology confirmed the presence of anaplastic meningioma, leading to the adjustment of her clinical management. This case shows the need for heightened suspicion and comprehensive evaluation in similar presentations to facilitate timely intervention and improve patient outcomes.
RESUMO
Background: The World Health Organization (WHO) grade 2 meningiomas behave aggressively with a high proclivity toward recurrence despite maximal surgical resection. Our institution, a pioneer of proton therapy, uses exclusively proton beam radiation, and thus, we present a retrospective cohort analysis of patients with WHO grade 2 meningiomas treated with adjuvant proton beam therapy (PBT) at our institution between 2007 and 2019. The effects of adjuvant PBT were evaluated. Methods: Data collected include diagnosis, gender, histological subtype, WHO grade, the extent of surgical resection, adjuvant PBT radiation, details of the PBT radiation, recurrence, any additional PBT radiation, systemic medical therapy, and disease-specific survival. Results: Among the WHO grade 2 meningiomas (n = 50) recommended PBT, 80% and 78% of patients with gross-total resection (GTR) and subtotal resection (STR), respectively, followed through with PBT. The median radiation dose of PBT was 59.5 Gy and 59.92 Gy for patients with GTR and STR, respectively, with a median of 33 fractions delivered in 1.8 Gy doses for both groups. Combined 3-year progression-free survival (PFS) was 96%, and 5-year PFS was 92%. Combined overall survival was 95% at five years. Minimal radiation side effects were reported with no grade 3 or higher toxicities. Conclusion: Our results suggest that adjuvant PBT is well tolerated with minimal radiation toxicity. Alternative to photon radiation, PBT may be considered at least as safe and effective for adjuvant treatment of WHO grade 2 meningiomas when it is available.
RESUMO
Primary tumors in the central nervous system, known as meningiomas, are frequently found and constitute a substantial proportion of tumor cases. Although generally benign, there are occasional cases where they might exhibit malignant characteristics. Anaplastic meningioma is a rare subtype of malignant meningiomas, representing only a small proportion of cases. We present the case of a 70-year-old female patient who presented to the Neurosurgery Clinic of University Hospital "Saint George" with clinical manifestations of monocular vision and blurry vision in the right eye for three months. On physical examination, unilateral ptosis and mydriasis were noted in the left eye. MRI revealed an extra-axial mass located supratentorial in the left temporopolar region affecting the wing of the left sphenoidal bone, invading the cavernous sinus, suppressing the left and right optic nerves, and involving the left orbit. Operative treatment was performed through a left pterional craniotomy and resection of the tumor mass by microsurgical technique. The subdural, epidural, and intraorbital mass were resected. Total removal of the tumor was not achievable and subtotal resection was performed. Pathology results showed that the tumor mass was anaplastic meningioma. Surgery-related complications were not observed. Postoperatively, the patient was mobilized on the day after intervention and the control CT scan showed no ischemic or hemorrhagic events. The patient experienced relief in her symptoms and was discharged on the fifth day. The patient underwent radiation therapy, resulting in the complete removal of the left tumor in the cavernous sinus. After six months, no tumor recurrence was found, and a long-term follow-up is planned to monitor for possible recurrence.
RESUMO
PURPOSE: We report the first case of extra-axial anaplastic meningioma with direct orbital extension for differential diagnosis of orbital tumors. CASE SUMMARY: An 83-year-old woman presented with a protruding left eye and a palpable mass on the forehead. A brain computed tomography scan revealed a huge sarcomatous mass that had directly invaded the surrounding tissues. We removed the tumor by craniotomy and found that it involved the extradural and intradural spaces, brain parenchyma, subcutaneous tissue, left temporalis, orbital roof, and the other frontal lobe across the midline. A cranioplasty was performed, and the orbital roof was reconstructed with artificial bone and bone cement. The final histological diagnosis was anaplastic meningioma. The left eyeball was restored to its normal position 1 month after the surgery. Also, visual acuity and eye movement of the left eye were preserved. CONCLUSIONS: Direct orbital extension of originated extra-axial cerebral convexity anaplastic meningioma is rare but should be considered in the differential diagnosis of a rapidly growing orbital mass.

Se presenta el caso clínico de un paciente que comenzó a presentar cefalea, vértigos, trastornos visuales y pérdida del equilibrio. Mediante la resonancia magnética se visualizó una imagen tumoral parietal izquierda de 3 cm diámetro, de localización extraaxial y contornos lobulados bien definidos, con gran captación no homogénea de contraste, rodeada de extenso edema perilesional. Se realizó angiotomografía, previa a la cirugía, en busca de irrigación y daño vascular. Se logró la resección de 95% de la lesión (grado II de Simpson), que incluyó duramadre adyacente infiltrada y respetó el seno longitudinal superior. Los resultados anatomopatológicos confirmaron que se trataba de un meningioma anaplásico de grado III, con criterio de tratamiento coadyuvante.
The case report of a patient who began presenting headache, vertigos, visual disorders and loss of balance is presented. By means of the magnetic resonance a left tumoral parietal image of 3 cm diameter was visualized, of extra-axial localization and well defined lobulated contours, with great non-homogeneous zones of contrast, surrounded by extensive perilesional edema. An angiotomography was carried out, previous to the surgery, looking for irrigation and vascular compromise. The resection of 95% of the lesion was achieved (grade II of Simpson) which included adjacent infiltrated dura madre and preserving the superior longitudinal sinus. Pathological results confirmed that it was an anaplastic meningioma grade III, with criterium for adyuvant treatment.
RESUMO
Meningiomas are usually benign neoplasms in which extracranial metastases occur very rarely. We report a case of multiple extracranial metastases of an atypical meningioma following a local recurrence. A 68-year-old man presented with left-side motor weakness and dysarthria for two weeks. A computed tomography (CT) scan and magnetic resonance imaging (MRI) showed an intraventricular tumor. We performed a total mass removal, and the histopathologic findings were consistent with benign meningioma. Eight months later, the meningioma recurred. We performed a reoperation and whole brain radiation therapy postoperatively. The histopathologic findings showed atypical meningioma. Six months later, CT and MRI revealed metastases to multiple vertebrae, lung, ribs and perirenal soft tissue so a decompressive laminectomy with mass removal was performed. The histopathologic findings of the spinal tumors showed atypical meningioma. The results from perirenal biopsies were consistent with metastatic meningioma. In conclusion, extracranial metastasis as well as local recurrence must be considered in atypical or anaplastic meningioma. There must be regular follow-ups. Finally, an evaluation of the chest, abdomen and bone is necessary, especially when related symptoms or signs develop.

Meningioma without dural attachment usually occurs in the intraventricular region, the pineal region, and the sylvian fissure. However, subcortical meningioma located far from such locations is extremely rare. The authors report a case of subcortical anaplastic meningioma without any dural attachment in a 41-year-old woman.

This is a report of the clinico-pathologic findings in six cases of histologically verified malignant meningiomas-three hemangiopericytic and three anaplastic types. They were three males and three females and two of them were reoperated for recurrence. The hemangiopericytic types had similar angiographic and macroscopic features and malignant characteristics such as increased mitoses. The anaplastic types lacked typical arrangement, but had a large number of mitoses, increased cellularity, focal necrosis, pleomorphism, anaplasia, and the adjacent normal parenchymal infiltration. However the metastasis was not yet proven in these cases.
