Abstract
BACKGROUND Surgical management of parasagittal meningiomas (PMs) remains controversial in the literature. The need to pursue a resection as radical as possible and the high risk of venous injuries contribute to making the sinus opening a widely argued choice. This study aimed to analyze factors affecting the risk of recurrence and to assess clinical outcomes of patients who underwent surgical resection of PMs with conservative or aggressive management of the intrasinusal portion. METHODS A single-institution retrospective review of all patients with PM surgically treated between January 2013 and March 2021 was conducted. RESULTS Among 56 patients, the sinus was opened in 32 patients (57%), and a conservative approach was used in 24 patients (43%). The sinus opening was found to be a predictive factor of radical resection (Simpson grade [SG] I-II) (P = 0.007). SG was the only predictive factor of recurrence (P < 0.001). The radical resection group (SG I-II) showed recurrence-free survival at 72 months of about 90% versus 30% in the non-radical resection group (SG III-IV) (log-rank test = 14.21, P < 0.001). Aggressive management of the sinus and radical resection were not found to be related to permanent deficit (P = 0.214 and P = 0.254) or worsening of Karnofsky performance scale score (P = 0.822 and P = 0.933). CONCLUSIONS Removal of the intrasinusal portion of the tumor using standard procedures is not associated with a higher risk of permanent deficit or worsening of Karnofsky performance scale and reduces the risk of recurrence.

Comparison of Short-Term Surgery Outcomes and Clinical Characteristics Between Elderly and Non-Elderly Patients with Middle Third Parasagittal and Parafalcine Meningiomas. Neuropsychiatr Dis Treat 2023; 19:2331-2340. [PMID: 37928167 PMCID: PMC10624188 DOI: 10.2147/ndt.s428341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 10/24/2023] [Indexed: 11/07/2023] Open
Abstract
Purpose This study aims to compare the short-term surgery outcomes of the resection of meningiomas and clinical characteristics between elderly and non-elderly patients. Patients and Methods This retrospective study included patients who underwent a resection of middle third parasagittal and parafalcine meningiomas between January 2011 and December 2020. All lesions arise from the middle third of the parafalcine or infiltrate superior sagittal sinus (SSS). The clinical characteristics studied included neurological deficit, peritumoral brain edema (PTBE), SSS invasion, tumor size, and symptoms; perioperative complications, and short-term surgery outcomes including neurological deficit, operative blood loss, postoperative hospitalization duration, and WHO classification were compared. Results A total of 43 elderly patients and 63 non-elderly patients were included. Compared with non-elderly patients, elderly patients had larger lesions (P = 0.013) and presented with a larger PTBE (P = 0.019). SSS blockage was identified in 28.57% of elderly patients and 19.57% of non-elderly patients. Compared with non-elderly patients, elderly patients tended to suffer from more aggressive lesions (WHO II/III meningioma 6 vs 3, P = 0.154) and presented with longer postoperative hospital stays (17.25 ± 5.8 vs 13.50 ± 3.8, P = 0.009); conversely, while the non-elderly patients experienced more blood loss (P = 0.022) and had more perioperative reoperations (3 vs 1). No significant difference in neurological deficit was detected between the two groups (P = 0.97). After total tumor resection, patients with neurological deficits in both groups can recover during the follow-up period. Conclusion Among the 106 patients with middle third parasagittal and falx meningiomas in our hospital, elderly patients had larger lesions, presented with more severe PTBE, and had longer postoperative hospital stays than younger patients. Conversely, younger patients had more blood loss and serious complications than elderly patients. Postoperative neurological dysfunction in elderly patients was similar to that in middle-aged and young patients.

Ann Med Surg (Lond) 2023; 85:1162-1165. [PMID: 37113867 PMCID: PMC10129188 DOI: 10.1097/ms9.0000000000000354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 02/12/2023] [Indexed: 04/29/2023] Open
Abstract
Meningiomas are intracranial extracerebral tumors derived from arachnoid cells of the neural crest. They represent ∼20% of primary intracranial tumors and are seen as more common in elderly patients and women. Recurrence of meningioma can be observed during the early years after surgical treatment, but their occurrence within 10 years is rare. Case presentation In this report, the authors discuss a case of a 75-year-old patient with a recurrence of a frontal meningioma after 10 years of successful surgical resection. Our patient was a female who presented amnesia and memory lapses associated with several weeks of progressive heaviness of the lower limbs accompanied by speech heaviness, intense headaches, asthenia, consciousness disorder, and tonic-clonic convulsive seizures for 10 days. The patient had previously been treated for a benign meningioma by surgical excision. Imaging was performed, and recurrent frontal meningioma was retained as a final diagnosis. The patient underwent a successful total resection of her frontal tumor. Clinical discussion Recurrent tumors after complete surgical removal of meningiomas are rare and may be associated with microscopic residues. The more radical the surgery, the lower the risk of observing a recurrence. Adjuvant radiotherapy can be proposed, but the evidence is still lacking. Careful follow-up of all patients with or without complete surgical resection is therefore recommended. Conclusion This case illustrates the importance of suspecting recurrence of meningioma in adult patients after successful surgical excision, even after 10 years of free disease. Clinicians should be aware of long-term meningioma recurrence in this population, and imaging is key for a positive diagnosis.

Abstract
Objectives Parasagittal meningioma resection is prone to postoperative complications and tumor recurrence because the tumor invades the superior sagittal sinus. This study aimed to clarify the incidence of perioperative complications and the recurrence of superior sagittal paranasal meningiomas and explored potential predictors in this context. Methods The study retrospectively reviewed the clinical, imaging, and follow-up data of parasagittal meningiomas among patients who underwent microsurgical resection in the authors' institution from January 2008 to December 2017. Univariate and multivariate logistic regression analyses were conducted to explore independent predictors of perioperative complications and tumor recurrence. Results A total of 212 parasagittal meningioma patients were included in this study. The incidence of perioperative complications was 23.6% (50/212), and perioperative death occurred in 6 (2.8%) patients. In univariate and multivariate logistic regression analyses of perioperative complications, peritumoral edema ≥1 cm (odds ratio [OR] 2.163, 95% confidence interval [CI] 1.057-4.428, P = 0.035) and the Sindou invasion Class V-VI(OR0.018, 95% CI 1.248-11.064, P = 0.018) were independent predictors. After an average of 83 (39-154) months of clinical follow up among the living 206 patients, 22 (10.7%) patients showed tumor recurrence. In univariate and multivariate logistic regression analyses of tumor recurrence, the Sindou invasion Class III-IV (OR 5.539, 95%CI 1.469-20.884, P = 0.011) and the Sindou invasion Class V-VI (OR 9.144, 95%CI 2.215-37.757, P = 0.002) were independent predictors. Conclusions Peritumoral edema ≥1 cm and the Sindou invasion Class V-VI were the independent predictors of perioperative complications, and the Sindou invasion Class III-IV and the Sindou invasion Class V-VI were the independent predictors of tumor recurrence. The part of the parasagittal meningioma involving the sinus wall should be actively removed to the largest degree possible to reduce the recurrence rate.

Abstract
In a previous chapter, the surgical management of skull base meningiomas were discussed. However, the most common meningiomas that are diagnosed and operated on are non-skull base tumors located in the parasagittal/parafalcine region and convexity, and more rarely along the tentorium, and in an intraventricular location. These tumors present their own unique set of challenges given their unique anatomy and tend to be more biologically aggressive compared to skull base meningiomas, thereby reinforcing the importance of obtaining a gross total resection if possible, in order to delay recurrence. In this chapter we will cover the surgical management of non-skull base meningiomas with technical considerations for tumors located in each of the anatomical areas listed above.

Abstract
Background: Parasagittal meningioma (PSM) is a tumor located in the parasagittal angle which extends to and/ or invades the superior sagittal sinus (SSS). Surgical resection of the PSM, the standard treatment in such cases, poses a challenge for neurosurgery, particularly where there is an invasion of the SSS. This is due to the risk of complications through injury to the adjacent vascular structures. The objective of the study was to perform a comparative evaluation of the surgical techniques for total resection of the PSM (Simpson Grade [SG] I and SG II), which present the highest rates of success in terms of the following variables: mortality, recurrence, and postoperative complications. Methods: Fifty-six patients undergoing resection surgery for PSM with the invasion of the SSS were enrolled. The patients were divided into two groups: Group A, comprising 26 cases of patients subjected to SG I PSM resection surgery and Group B, with 31 cases of patients subjected to SG II PSM resection surgery, with preservation of the SSS. Results: The results showed that Group B had lower rates of postoperative deficit (P = 0.026), zero mortality, and reduced recurrence. The use of complementary radiotherapy for atypical meningiomas (WHO II) in Group B was satisfactory in controlling the disease. Conclusion: The Simpson II, with preservation of the SSS, was better as it diminishes the vascular risks of surgery, reduces the frequency of severe postoperative deficit, and reduces mortality.

Abstract
Objective: Parasagittal and falcine meningiomas are still a challenge in terms of surgical resection. Although maximal safe resection is the main therapeutic approach, numerous postoperative complications can still occur depending on the locations of these tumors. Moreover, previous studies have reported that parasagittal meningiomas have a higher recurrence rate than meningiomas with other locations. Patients, Materials and Methods: We retrospectively reviewed 21 patients with parasagittal and falcine atypical meningiomas [World Health Organization (WHO) grade II], nine of whom had their superior sagittal sinus (SSS) invaded by the tumor. We reviewed the demographic information, operative notes, pathological reports, and clinical and imagistic follow-up reports of each patient over a 5-year time span. Results: All the patients were surgically treated, and the tumor removal was grade II according to Simpson’s grading system in 47.6% and grade III in 19% of the cases. The SSS was invaded in 42.9% of the patients. No immediate mortality or morbidity was revealed by our study. Tumor recurrence/progression documented on postoperative imaging amounted to 14.3% and 19%, 12 and 24 months after surgery, respectively. Furthermore, 36, 48 and 60 months after the surgery, the recurrence rate remained the same, namely in 9.5% of the cases. The recurrence was higher in patients with SSS invasion than in patients with no SSS invasion. The tumor recurrence was slightly more predominant in women, i.e., 6% higher than in the male group. Conclusions: In our group of patients with parasagittal and falcine meningiomas, we report a 47.6% Simpson II resection rate and 19% Simpson III resection rate associated with a very low complication rate and no immediately postoperative morbidity and mortality, compared to more aggressive techniques. The recurrence of parasagittal meningiomas predominated after grade III and IV Simpson resection and dural sinus invasion was a negative predictive factor for recurrence. Therefore, the surgery of parasagittal and falcine meningiomas is beneficial, both for tumor control, but also for improving neurological outcome. Aggressive meningioma resection should be balanced with the increased neurosurgical risk.

Abstract
BACKGROUND Acute occlusion of the posterior sagittal sinus may lead to dramatic increase in intracranial pressure (ICP), refractory to standard treatment. Hybrid vascular bypass of cranial venous outflow into the internal jugular vein (IJV) has seldom been described for this in recent neurosurgical literature. OBJECTIVE To describe creation of a novel vascular bypass shunt from the superior sagittal sinus (SSS) to internal jugular vein (IJV) utilizing a covered stent-Dacron graft construct for control of refractory ICP. METHODS We illustrate a patient with refractory ICP increases after acute sinus ligation that was performed to halt torrential bleeding from intraoperative injury. A temporary shunt was created that successfully controlled ICP. From the promising results of the temporary shunt, we utilized a prosthetic hybrid bypass graft to function as a shunt from the sagittal sinus to IJV. Yet the associated anticoagulation led to complications and a poor outcome. RESULTS Rapid and sustained ICP reduction can be expected after sagittal sinus-to-jugular bypass shunt placement in acute sinus occlusion. Details of the surgical technique are described. Heparin anticoagulation, while imperative, is also associated with worrisome complications. CONCLUSION Acute occlusion of posterior third of sagittal sinus carries a very malignant clinical course. Intractable intracranial hypertension from acute sinus occlusion may be effectively treated with a SSS-IJV bypass shunt. A covered stent construct provides an effective vascular bypass conduit. However, the anticoagulation risk can lead to fatal outcomes. The neurosurgeon must always strive for primary repair of an injured sinus.

Long-term outcome of Simpson IV meningioma resection: Would it improve with adjuvant SRS? Clin Neurol Neurosurg 2021; 207:106766. [PMID: 34166979 DOI: 10.1016/j.clineuro.2021.106766] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 06/14/2021] [Accepted: 06/15/2021] [Indexed: 12/21/2022]
Abstract
OBJECTIVE Subtotal meningioma resection (STR) is often performed to minimize surgical morbidity. Nevertheless, only a few studies have reported on patient outcome after STR. We studied the long-term outcome of SIV (Simpson grade IV) resection and identified predictive factors of overall survival (OS), progression-free survival (PFS) and time to progression (TTP). METHODS A retrospective analysis was performed on 68 patients who underwent SIV resection of meningioma (grade I) from 2004 to 2010. Data were collected from clinical, surgical and pathology records and radiological imaging. Long-term outcomes were evaluated at least 10 years after surgery. RESULTS Permanent morbidity was 11.8%, 30-day mortality 2.9% and progression rate 50.0% for a median follow-up duration of 126.6 months. Median TTP was 86.2 months. Adjuvant SRS was the only significant factor associated with longer PFS (p = 0.0052) and TTP (p = 0.0079). Higher age (p = 0.0022), KPS (p = 0.0182), postoperative ECOG score (p = 0.0182) were reliable predictors of shortened OS and aSRS (p = 0.0445) was reliable predictor of longer OS. CONCLUSION STR in intracranial meningioma is still viable and often the only treatment option available in high-risk patients or high-risk tumors. Although surgical morbidity and mortality are high, the OS rate was 85.3% at 5 years and 79.4% at 10 years. Because of the considerable progression rate and rather a long term OS the adjuvant SRS should be considered following SIV resection.

Abstract
BACKGROUND As the predictive role of many risk factors for parasagittal meningioma (PM) recurrence remains unclear, the objective of the meta-analysis was to make a comprehensive assessment of the predictive value of selected risk factors in these lesions. METHODS Studies including data on selected risk factors, such as histology, tumor and sinus resection, sinus invasion, tumor localization, and immediate postoperative radiotherapy for PMs recurrence, were searched in the NCBI/NLM PubMed/MEDLINE, EBM Reviews/Cochrane Central, ProQuest, and Scopus databases, and analyzed using random effects modeling. RESULTS Thirteen observational studies involving 1243 patients met the criteria for inclusion in the meta-analysis. WHO grading of meningiomas was identified as the most powerful risk factor for recurrence. WHO grade II meningiomas (OR 11.61; 95% CI 4.43-30.43; P < .01; I2 = 31%) or composite group of WHO grades II and III (OR 14.84; 95% CI 5.10-43.19; P < .01; I2 = 48%) had a significantly higher risk of recurrence than benign lesions. Moreover, an advanced sinus involvement (types IV-VI according to the Sindou classification) (OR 3.49; 95% CI 1.30-9.33; P = .01; I2 = 0%) and partial tumor resection (Simpson grades III-V) (OR 2.73; 95% CI 1.41-5.30; P = .03; I2 = 52%) were associated with a significantly higher risk of recurrence than their counterparts. CONCLUSION Among the selected risk factors, high-grade WHO lesions, advanced sinus invasion, and partial tumor resection were associated with a higher risk of PM recurrence, with WHO grading system being the most powerful risk factor.

Long-term outcomes of multimodality management for parasagittal meningiomas. J Neurooncol 2020; 147:441-450. [PMID: 32088814 DOI: 10.1007/s11060-020-03440-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2019] [Accepted: 02/17/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE The aim of this study was to systematically analyze the clinical characteristics of a large cohort of parasagittal meningioma (PM) and to evaluate the patients' outcomes and best treatment strategies based on tumor features. METHODS To minimize selection bias we performed a single-institutional review of PM with restricted criteria. One hundred and ninety-two consecutive patients who met criteria for inclusion were reviewed from 2003 to 2011 in our general hospital. RESULTS A total of 131 cases (68.2%) were with WHO grade I, while grade II and grade III PMs constituted 40 (20.8%) and 21 cases (10.9%). Higher histological grade was associated with loss of trimethylation of H3K27 (P = 0.000). For WHO grade I PMs, GTR was significantly associated with a better PFS (P = 0.023); however, adjuvant radiotherapy did not benefit patients with STR (P = 0.215). For de novo high-grade (WHO grade II and III) PMs (n = 37), adjuvant radiotherapy was associated with a significantly longer OS (P = 0.013), while no difference was observed between GTR and STR (P = 0.654). In recurrent high-grade PM patients (n = 24), GTR combined with adjuvant radiotherapy increased PFS (P = 0.005). CONCLUSIONS This study demonstrated that PMs were a heterogeneous group of tumors with a high proportion of high-grade tumors that often displayed aggressive clinical behaviors. Low-grade PM benefited from radical resection, whereas high-grade de novo PM did not. Adjuvant radiotherapy significantly prolonged OS for high-grade primary PM, but did not impact survival of patients with subtotally resected low-grade tumors. Long-term outcome of high-grade recurrent PMs was dismal. We thus show that extent of tumor resection, tumor grade and tumor recurrent status inform therapeutic decisions for PMs.

Abstract
We know that the extent of resection is the greatest predictor of long-term survival. However, the potential tradeoff for gross total resection in difficult locations is diminished quality of life. Benign subtotally resected or small incidentally discovered meningiomas may be followed clinically especially in the elderly. In addition, radiosurgery plays a role in the treatment of meningiomas as a primary treatment modality, or as a salvage therapy. Decisions regarding management should be made with an understanding of the natural history and rate of growth. In this chapter we review the known meningioma epidemiology as well as the growth patterns of meningiomas based upon location.

Abstract
Context: The management of parasagittal and falcine meningiomas centers around the relationship between the tumor and the venous anatomy of the superior sagittal sinus (SSS) and the bridging veins. Aims: The present study aims to address neurosurgical outcomes in a cohort of patients with parasagittal and falcine meningiomas >2.0 cm in the largest diameter, in which a neurosurgical/multidisciplinary treatment was considered. Settings and Design: The clinical outcomes of patients undergoing neurosurgical management for parasagittal and falcine meningiomas at the authors’ institution over a 15-year period were analyzed. Analysis was limited to those tumors (primary, residual, or recurrences) >2.0 cm in the largest diameter. Subjects and Methods: The authors identified 100 patients with parasagittal/falcine meningiomas >2.0 cm in their largest diameter, who underwent neurosurgical treatment at their institution between 1999 and 2013. Statistical Analysis Used: Tumor control was assessed using Kaplan–Meier analysis, and specific attention was paid to the relationship between the tumor and the SSS and its impact on tumor control and outcome. Results: There was no difference in rates of tumor control in patients who received subtotal resection for a WHO Grade I tumor, followed by close observation, compared with those undergoing gross-total resection, primarily because no cases were observed in which the tumor remnant in the SSS demonstrated interval growth on serial imaging studies. Of patients in this series, 13% experienced at least one neurological, medical, surgical, or radiosurgical complication, and the mortality was 0%. Conclusions: These data provide a more judicious optimization of the expected outcome that can be obtained with treatment of these tumors, in which a combination of image guidance, advanced microsurgical techniques, and conformal radiation treatments is used.

Abstract
BACKGROUND In the management of meningiomas invading the major venous sinuses, balance between tumor control and complication prevention is desirable. The aim of this study was to describe an institutional experience in management of meningiomas involving major venous sinuses. METHODS A retrospective study was carried out over 18 years, between 1999 and 2017, in patients with meningiomas involving major venous sinuses. Clinical features, operative strategy, histology, postoperative complications, adjuvant therapy, and long-term follow-up were studied. RESULTS The study included 84 patients. Neurologic deficits were seen in 26 (31%) patients at presentation. The recurrence rates in Simpson grade I, II, and III excision were 7.6%, 25%, and 29.4% at a mean follow-up of 45.4 months (range, 1-192 months). No intervention of the involved sinus was done in 64 (76%) cases, venotomy was done in 3 (3.5%) cases, sinus resection without graft was done in 14 (16.6%) cases, and sinus reconstruction with patch was done in 3 (3.5%) cases. There were 53 (67.0%) patients with World Health Organization grade I histology and 25 (31.6%) patients with World Health Organization grade II histology. Fifteen recurrences were treated with Gamma Knife radiosurgery. In univariate analysis using Cox proportional hazards model, World Health Organization grade (P = 0.036, hazard ratio 2.90, 95% confidence interval = 1.07-7.87) and Simpson grade (P = 0.017, hazard ratio 2.90, 95% confidence interval = 1.18-5.29) were found to be significant factors to predict tumor recurrence. CONCLUSIONS Management of meningiomas involving major venous sinus with microsurgical techniques and adjuvant Gamma Knife radiosurgery achieves a good tumor control rate with an acceptable complication rate.

Abstract
BACKGROUND Parasagittal and parafalcine (PSPF) meningiomas recur more frequently than other intracranial meningiomas owing to the difficulty in achieving gross total resection. The present study investigated the preoperative magnetic resonance imaging (MRI) features for the prediction of progression/recurrence (P/R) in benign PSPF meningiomas with an emphasis on the apparent diffusion coefficient (ADC) values. METHODS We retrospectively investigated the preoperative MRI features for the prediction of P/R in benign (World Health Organization grade I) PSPF meningiomas. Only patients who had undergone preoperative and postoperative MRI follow-up studies for ≥1 year were included. From October 2006 to December 2015, 48 patients with a diagnosis of benign PSPF meningioma were included (median follow-up period, 42.5 months). Of these 48 patients, 12 (25%) developed P/R (median time to P/R, 23 months). RESULTS PSPF meningiomas in male patients, subtotal resection, large tumor diameter, high diffusion-weighted imaging signal, and lower ADC values or ratios were significantly associated with P/R (P < 0.05). The cutoff points of the ADC value and ADC ratio for the prediction of P/R were 0.83 × 10-3 mm2/second and 0.99, with an area under the curve of 0.82 and 0.83, respectively (P = 0.001). On multivariate Cox proportional hazards analysis, male sex and low ADC values (<0.83 × 10-3 mm2/second) were high-risk factors for P/R, with a hazard ratio of 12.37 and 30.2, respectively (P < 0.05). Kaplan-Meier analysis showed that lower ADC values and ratios predicted for significantly shorter progression-free survival (P < 0.05). CONCLUSIONS The preoperative ADC values and ratios for the prediction of P/R offer additional valuable information for the treatment planning for PSPF meningiomas.

Optimal surgical strategy for meningiomas involving the superior sagittal sinus: a systematic review. Neurosurg Rev 2018; 43:525-535.

Abstract
Involvement of the superior sagittal sinus (SSS) by meningiomas poses specific challenges, without an agreement about the degree of surgical aggressiveness when dealing with these lesions. In this systematic review and meta-analysis, we compare outcomes and complication rates, after different surgical strategies. Studies focused on meningiomas involving the SSS were collected from numerous online databases. Surgical outcome and complication data were abstracted. Comparisons were made considering complication and recurrence rates between an "aggressive" and a "non-aggressive" surgical attitude. A total of 26 studies, encompassing 1614 patients, were identified. Most of the tumors (53%) arose from the middle third of SSS and 75% of patients had a patent sinus at the time of surgery. A favorable outcome was achieved in 73% of patients treated with an "aggressive" surgical attitude compared to 78% of patients treated with a "non-aggressive" surgical attitude. Complication rates were similar between "aggressive" and "non-aggressive" attitudes, except for a higher rate of venous infarct (4% versus 2%, respectively) and worsening of preexisting motor deficits (34% versus 13%, respectively) in aggressively treated patients. Recurrence rates were not substantially different in the two groups after accounting for length of follow-up. Patients with incomplete resection (Simpson grades II-V) or with high histological grade (WHO grade III) had significantly higher recurrence rates. A complete resection achieves higher rates of tumor control, however, without nullifying the risk of recurrence. Moreover, "aggressive" tumor removal is associated with higher rates of venous complications and worsening of preexisting motor deficits.

Abstract
BACKGROUND Sinus pericranii is a rare vascular anomaly characterized by abnormal connections between the extra- and intracranial venous systems. Although the etiology still remains unclear, sinus pericranii is usually congenital in nature, or less likely may be secondary to spontaneous or traumatic causes. CASE DESCRIPTION We present a unique case of spontaneous sinus pericranii secondary to a parasagittal meningioma invading and occluding the superior sagittal sinus, torcula herophilii, and bilateral transverse sinuses. The resultant venous outlet obstruction and venous hypertension may have been the inciting factors for the development of the collateral channel connecting the intra- and extracranial venous systems. CONCLUSIONS This case highlights the effect of the reversal of normal venous outflow secondary to meningiomatous occlusion of intracranial dural sinuses. Sinus pericranii may, on rare occasions, represent the sole means for intracranial venous drainage in cases of intracranial venous thrombosis or incomplete development of the cerebral venous system. Therefore, this case also highlights the importance of pretreatment evaluation of the venous drainage system in patients with sinus pericranii and those with meningiomas.

Abstract
OBJECTIVE Accurate knowledge of the anatomy of the straight sinus (SS) is relevant for surgical purposes. During one surgical procedure involving the removal of part of the SS wall, the authors observed that the venous blood flow was maintained in the SS, possibly through a vein-like structure within the dural sinus or dural multiple layers. This observation and its divergence from descriptions of the histological features of the SS walls motivated the present study. The authors aimed to investigate whether it is possible to dissect the SS walls while keeping the lumen intact, and to describe the histological and ultrastructural composition of the SS wall. METHODS A total of 22 cadaveric specimens were used. The SS was divided into three portions: anterior, middle, and posterior. The characteristics of the SS walls were analyzed, and the feasibility of dissecting them while keeping the SS lumen intact was assessed. The thickness and the number of collagen fibers and other tissues in the SS walls were compared with the same variables in other venous sinuses. Masson's trichrome and Verhoeff's stains were used to assess collagen and elastic fibers, respectively. The data were analyzed using Zeiss image analysis software (KS400). RESULTS A vein-like structure independent of the SS walls was found in at least one of the portions of the SS in 8 of 22 samples (36.36%). The inferior wall could be delaminated in at least one portion in 21 of 22 samples (95.45%), whereas the lateral walls could seldom be delaminated. The inferior wall of the SS was thicker (p < 0.05) and exhibited less collagen and greater amounts of other tissues-including elastic fibers, connective tissue, blood vessels, and nerve fibers (p < 0.05)-compared with the lateral walls. Transmission electron microscopy revealed the presence of muscle fibers at a level deeper than that of the subendothelial connective tissue in the inferior wall of the SS, extending from its junction with the great cerebral vein to the confluence of sinuses. CONCLUSIONS The presence of a structure within the SS that can maintain the venous blood flow despite the dural wall might be considered an anatomical variation. The greater thickness of the inferior wall of the SS compared with the lateral walls is mainly due to the presence of larger amounts of tissues other than collagen. Delamination of the inferior wall of the SS was mostly possible in its inferior wall, but an attempt to delaminate the lateral walls is not recommended. Ultrastructural assessment corroborated a recent report of the presence of muscle fibers in the inferior wall of the SS.

Abstract
Various complications including air embolism have been discussed in large clinical series regarding the parasagittal meningioma. We presented and discussed the patient suffering from persistent hypotension after excision of parasagittal meningioma. A 47-year-old man was admitted to our hospital with complaints of headache and frontal region swelling. His cranial MRI showed a bilaterally located parasagittal meningioma at the anterior one third of the sagittal sinus. Conspicuously, he had large frontal sinus and its length was about totally 7 cm in sagittal and transverse part.During cranitomy, we had to open frontal sinus because of its large size and open the sagittal sinus while removing of the tumor. So coincidental opening of the superior sagittal sinus and/or emissary veins located within diploe of the cranium and frontal sinus may cause hypotension after extubation due to normal respiration led to air escaping from the frontal sinus to the emissary veins placed next to the frontal sinus. Bilateral application of the tamponade embedded with vaseline inside to the nose prevents air escaping from the frontal sinus to the emissary veins.

Abstract
OBJECTIVE We present our experience with surgery of parasagittal and falcine meningiomas invading the superior sagittal sinus with special consideration of the surgical complications and the incidence of tumour recurrence. MATERIALS AND METHODS The analysis included 37 patients with parasagittal and falcine meningiomas invading the superior sagittal sinus. In 13 cases, the sinus was ligated and resected with tumour. In 14 cases, the sinus was entered with the goal of tumour resection and the sinus was reconstructed, while in 10 patients the sinus was not entered and the remaining residual tumour was observed for growth. RESULTS Out of 13 patients after radical resection of the tumour and invaded part of sinus, 9 revealed haemodynamic complications: venous infarction (4), significant brain oedema (3) and hypoperfusion syndrome (2). 2 out of 14 patients after resection of the tumour from the lumen of the superior sagittal sinus with subsequent sinus repair developed venous infarction after surgery. Among 27 patients after radical tumour excision the remote follow-up revealed recurrence in 2 patients. There were no significant haemodynamic complications in none of 10 cases, in which the residual tumour was left after surgery in the superior sagittal sinus. In this group, 3 cases were subjected to early post-operative radiotherapy and local recurrence was observed in 4 patients. CONCLUSIONS The aggressive surgical treatment of meningiomas infiltrating the superior sagittal sinus is associated with a high surgical risk. The incidence of recurrence of these tumours increases significantly in the case of non-radical excision of the tumour.

Abstract
Intrinsic meningiomas of the superior sagittal sinus pose a significant technical challenge, particularly in the posterior two-thirds of the sinus. Resection is curative but frequently is not possible because of the involvement of critical vascular structures. Here, the authors present the case of a 49-year-old woman with a recurrent meningioma located exclusively in the posterior two-thirds of the sagittal sinus. The patient was treated with a margin dose of 12 Gy and a maximum dose of 24 Gy to the length of the tumor, which measured 16 cm. Five years after treatment, the tumor remains stable and the patient is symptom free. This case demonstrates the unique role that stereotactic radiosurgery can play in the management of meningiomas that are surgically unresectable and have no accepted form of treatment. To the authors' knowledge, 16 cm also represents the longest segment of tumor treated using stereotactic radiosurgery.

Abstract
The aim of the present study was to determine the efficacy of microsurgery treatment for parasagittal meningioma in the central gyrus region. A microsurgical technique was used to treat 26 patients with large parasagittal meningioma in the central gyrus region. The Rolandic and draining veins and the peritumoral normal brain tissue were retained, and the associated sagittal sinus was appropriately protected. A Simpson grade I, II or III resection was performed in 8 (30.8%), 12 (46.2%) and 6 (23.1%) patients, respectively, with no post-operative mortalities. Following treatment, 9 patients exhibited hemiparalysis. No tumor recurrence was found in 21 patients during the follow-up examination. The treatment protocol described in the current study included sufficient pre-operative imaging evaluations, a skilled microsurgical technique, improved protection of the Rolandic vein and treatment of the sagittal sinus, and was found to significantly increase the total tumor removal rate and decrease post-operative recurrence.

Abstract
BACKGROUND Maximal safe resection is the goal of correct surgical treatment of parasagittal meningiomas, and it is intimately related to the venous anatomy both near and directly involved by the tumor. Indocyanine green videoangiography (ICGV) has already been advocated as an intra-operative resourceful technique in brain tumor surgery for the identification of vessels. The aim of this study was to investigate the role of ICGV in surgery of parasagittal meningiomas occluding the superior sagittal sinus (SSS). METHOD In this study, we prospectively analyzed clinical, radiological and intra-operative findings of patients affected by parasagittal meningioma occluding the SSS, who underwent ICGV assisted-surgery. Radiological diagnosis of complete SSS occlusion was pre-operatively established in all cases. ICGV was performed before dural opening, before and during tumor resection, at the end of the procedure. RESULTS Five patients were included in our study. In all cases, ICGV guided dural opening, tumor resection, and venous management. The venous collateral pathway was easily identified and preserved in all cases. Radical resection was achieved in four cases. Surgery was uneventful in all cases. CONCLUSIONS Despite the small number of patients, our study shows that ICG videoangiography could play a crucial role in guiding surgery of parasagittal meningioma occluding the SSS. Further studies are needed to define the role of this technique on functional and oncological outcome of these patients.

Abstract
OBJECT Surgical treatment of parasagittal meningiomas is challenging. Preserving the venous outflow is the key point, but this may preclude radical resection. Different surgical strategies have been proposed. To contribute to the debate on the optimal strategy for treating these tumors, a single-institutional, single-surgeon series of patients with parasagittal meningiomas was analyzed and the available literature reviewed. METHODS Clinical charts of patients with parasagittal meningioma, managed at the University of Messina between 1988 and 2008, were retrospectively reviewed. A microsurgical resection, the goal of which was to preserve the venous outflow, was performed. Only if the superior sagittal sinus (SSS) was angiographically occluded, but if alternative venous outflow was clearly recognized, was the tumor resected, together with the sinus without further flow restoration. A MEDLINE review of the literature published between 1955 and 2011 was performed. RESULTS Long-term follow-up (mean 80 months) data obtained in 67 patients with meningiomas involving the SSS were analyzed. The recurrence rate was 10.4%; the morbidity and mortality rates were 10.4% and 4.5%, respectively. The authors identified in the literature 19 relevant studies on this issue, and based on their review of the literature, there is no evidence that aggressive management offers an advantage in terms of recurrence rate. CONCLUSIONS Analysis of the data obtained in the 67 patients confirmed good outcome and long-term tumor control following a surgical strategy aimed to preserve venous outflow. These findings and the results of the authors' analysis of the literature emphasize that the goal of radical tumor resection should be balanced by an awareness of the increased surgical risk attendant on aggressive management of the SSS and bridging veins.

Abstract
BACKGROUND To the authors' knowledge, meningiomas of the posterior third of the falx and the parasagittal sinus have never been specifically described to date and correlated visual outcome remains unclear. With this retrospective study we describe the clinical characteristics of these tumours, their surgical management, and the improvement in visual disturbances after surgery. METHODS Twenty-six consecutive patients (22 females, 4 males; mean age, 54 years) operated on for parasagittal (n = 22) and falcine (n = 4) meningioma between 1990 and 2010 were analysed retrospectively. Preoperative planning included magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) or angiography. Sinus invasion was classified as normal, stenotic or occluded from the imaging findings and according to the Sindou classification from the intraoperative notes. RESULTS Visual disturbances and headache (in 21 and 14 cases, respectively) were the most commonly referred symptoms; visual field deficit was present in 19 patients. Simpson grade I was obtained in four patients, grade II in 15, grade III in three, and grade IV in four. The main limiting factor for total removal was sinus involvement. No perioperative deaths or relevant postoperative complications occurred. The mean follow-up was 107 months. Visual field deficit improved or resolved in almost half of the patients during the follow-up period. Three (12%) patients relapsed, two were treated with Gamma Knife surgery (stable at current writing) and the third died of disease progression. CONCLUSIONS Outcome after surgery compares favourably with other parasagittal meningioma localisations and overall morbidity is negligible. Visual function is crucial for clinical outcome. Since an improvement of the deficit might still be possible, every effort should be undertaken to preserve the visual cortex.

Abstract
Object
Convexity meningiomas are expected to have a low recurrence rate given their classically “easy resectability.” Nonetheless, recurrence can occur. Factors playing a role in their recurrence are analyzed here, including the extent of resection and tumor histological type, among others, with a special emphasis on the cleavage plane.
Methods
The authors reviewed 100 cases of convexity meningiomas surgically treated between 1987 and 2001 with a median follow-up of 86 months (range 2–16 years). Preoperative and postoperative functional status, Simpson resection grade, histological type, and intraoperative surgical plane with pial vessel invasion were studied and correlated with the recurrence rate.
Results
The average tumor size was 3.6 ± 0.4 cm. The pre- and postoperative Karnofsky Performance Scale scores were 92.6 ± 4.6 and 97.9 ± 2.2, respectively. Ninety-five lesions were benign (WHO Grade I) and 5 were atypical (WHO Grade II). Ninety-one and 9 tumors were subjected to Simpson Grade 1 and 3 resections (three Grade 3a and six Grade 3b), respectively. Surgical deaths did not occur. After a mean follow-up of 7.2 years, 4 meningiomas recurred; 2 (2.2%) after Simpson Grade 1 resections and 2 after Simpson Grade 3 (3a and 3b) resections (22.2%; p = 0.0034). When just the subgroup of Simpson Grade 1/WHO Grade I was studied, the recurrence rate decreased to 1.2% (1 of 86 cases). The recurrence of WHO Grade I tumors was higher in the subpial group than in the extrapial group (p = 0.025). No difference in recurrence according to the cleavage plane was seen in the WHO Grade II subgroup (p = 0.361). As for the subpial group, no difference in recurrence was noted between the WHO Grade I and II subgroups (p = 0.608). Importantly, however, the extrapial subgroup of WHO Grade II lesions had a higher recurrence rate compared with its counterpart in the WHO Grade I subgroup (p = 0.005).
Conclusions
Pial and vascular invasion affect the recurrence rate in convexity meningioma surgery. The recurrence rate of WHO Grade I tumors was higher among those with a subpial plane of dissection than among those with an extrapial one. Histological type did not determine the degree of pial invasion in WHO Grade I and II lesions.

Abstract
OBJECT The management of parasagittal and falcine meningiomas centers around the relationship between the tumor and the venous anatomy of the superior sagittal sinus (SSS) and the bridging veins. The present study aims to address surgical outcomes in a focused cohort of these patients for which there is not clinical equipoise between radiosurgery and transcranial resection. METHODS The clinical outcomes of patients undergoing surgical removal of parasagittal and falcine meningiomas at the authors' institution over an 18-year period were analyzed. Analysis was limited to patients with large, symptomatic, or rapidly growing tumors, for whom radiosurgery was not a good option. Tumor control was assessed using Kaplan-Meier analysis, and specific attention was paid to the relationship between the tumor and the SSS, and its impact on tumor control and outcome. RESULTS The authors identified 135 patients with large, symptomatic, and/or growing parasagittal/falcine meningiomas who underwent resection at their institution between 1991 and 2007. The median length of follow-up was 7.6 years (range 1.7-18.6 years). The SSS was found to be invaded in 61 of 135 cases. In 6 cases the sinus was completely occluded. In 33 of the remaining 55 cases, the tumor invading the sinus was able to be removed with simple microsurgical techniques. There was no difference in rates of tumor control in patients who received subtotal resection for a WHO Grade I tumor, followed by close observation, compared with those undergoing gross-total resection, primarily because no cases were observed in which the tumor remnant in the SSS demonstrated interval growth on serial imaging studies. Of the patients in this series, 19% experienced at least one neurological, medical, or surgical complication. CONCLUSIONS Importantly, these data provide a more modern estimate of the expected outcomes that can be obtained with treatment of these tumors, in which a combination of image guidance, advanced microsurgical tools, and conformal radiation treatments is used.

Abstract
Purpose Survival after brain or spinal cord neoplasms is poor and varies by diagnostic group, age, grade, treatment and pretreatment factors, and location and size of tumor. We carried out a study to investigate survival and factors affecting survival of all diagnostic types of second primary brain or spinal cord neoplasms. Patients and Methods The British Childhood Cancer Survivor Study (BCCSS) is a long-term population-based follow-up study of 17,980 5-year survivors of childhood cancer. We used relative survival and multivariate Cox regression analysis to determine 5-year relative survival and factors affecting survival in second primary meningiomas and gliomas that developed in survivors included in the BCCSS. Results There were 247 second primary brain or spinal cord neoplasms, including 137 meningiomas and 73 gliomas in a young adult population. Five-year relative survival after meningiomas was similar for males (84.0%; 95% CI, 72.6% to 91.1%) and females (81.7%; 95% CI, 69.9% to 89.3%). For gliomas, 5-year relative survival was 19.5% (95% CI, 8.6% to 33.7%) for males and females. Multivariate analysis showed significant heterogeneity by decade of treatment (P = .04), grade (P = .03), and genetic risk (P = .03) for rate of mortality after a meningioma. For gliomas, survival was significantly affected by grade (P < .001). Conclusion Our results indicate survival is poor after second primary glioma in this young adult population, although survival after second primary meningioma is good. Our study has clinical implications for the surveillance of childhood cancer survivors at risk of developing second primary brain tumors, in particular survivors of childhood acute lymphoblastic leukemia or childhood brain tumors.
