This case presents a 34-year-old man who had a huge parasagittal meningioma. Initial treatment consisted of preoperative external carotid artery embolization and partial tumor resection. During the resection, we found that the tumor invaded the adjacent calvarium, and due to massive hemorrhage, total removal of the tumor was impossible. The patient was treated with intraoperative radiation therapy (IORT) (25 Gy via 16 MeV) as an adjunctive therapy. Eight months after IORT, we were able to remove the tumor completely without surgical difficulties. IORT can be considered an useful adjunctive therapy for the superficially located, huge, and highly vascular meningioma.

Among intracranial meningiomas, falcotentorial meningiomas, occurring at the junction of the falx cerebri and tentorial dural folds, are extremely rare. Because of their deep location, they are surrounded by critical structures, and have been regarded as one of the most challenging lesions for surgical treatment. In this study, we describe our surgical strategy for falcotentorial meningiomas and provide a review of our experience.

BACKGROUNDThe subtemporal transtentoral approach has been reported for nearly two decades; however it was not well used due to some limitations in dealing with large and giant petroclival meningiomas. The clinical outcome and merit of the modified subtemporal transpetrosal apex approach in large and giant petroclival meningiomas, as well as the choices, the improvements and the therapy strategies of the microsurgical approach in such patients were evaluated in this study.
METHODSTotally 25 cases of large and giant petroclival meningiomas undergone the modified subtemporal transpetrosal apex approach between April 2004 and January 2010 were enrolled in this study. The choice and improvement of the approach, the basis of anatomy and related research, the effect of accessory equipment, the exposure of tumor and the changes of neurofunction pre- and post-operation were all reviewed retrospectively. The operation outcomes and complications in this approach were also compared with those in the transpetrous presigmoid approach done in 14 cases in the same period.
RESULTSAll 25 cases underwent the modified subtemporal transpetrosal apex approach under electrophysiologic monitoring of cranial nerves and brain stem function. Trochlear nerve was partly wrapped in 14 cases, totally wrapped but can be explored in the initial segment of the cerebellum tentorium in 8 cases, totally wrapped and could not be seen until tumor was partly removed in 3 cases. The cerebellum tentorium was cut along the temporal bone from the anterior part of the apex to the mastoid part of superior petrous sinus in 6 cases, from the posterior part of the apex to the mastoid part of superior petrous sinus in 19 cases. Gross tumor resection was accomplished in 17 (68%) patients, subtotal resection in 7 (28%) patients, and partial resection in 1 (4%) patient. The most common postoperative complication was new neurological deficits or aggravations of preexisting deficit (64%). Follow-up ranged from 3 to 69 months. Compared with the transpetrous presigmoid approach done in 14 cases in the same period, the modified subtemporal transpetrosal apex approach showed obvious advantages such as simplicity in manipulating, microinvasiveness, less time-consuming, less complication, higher rate of tumor resection though the rates of gross tumor resection might be of no significant difference.
CONCLUSIONSModified subtemporal transpetrosal apex approach has obvious advantages compared with the transpetrous presigmoid approach. Some complications need to be solved by practice and modification of the approach as well as the accumulation of the experiences.

OBJECTIVETo investigate the clinical applied anatomy in the region of anterior clinoid process, and to improve the therapeutic efficacy of clinoidal tumors.
METHODSTwelve patients with large meningiomas located in clinoid were surgically treated via the extended anterior and middle fossa combined with epidural approach between January 1998 and August 2004. The surgical outcome and follow-up results were reviewed retrospectively. Supraorbital-posterional approach and cranioorbital zygomatic approach were used when tumors involved cavernous sinus. Anterior clinoid process was grinded with high-speed drilling. Supply of tumors were blocked extradurally. Tumors were resected intradurally.
RESULTSOf the 12 cases in large meningiomas located in clinoid, 8 cases had total removal of tumors, 3 patients had subtotal removal. Of the 10 patients with pre-operative severe visual deterioration, 6 patients was markedly improved, one patient unchanged and one patient worsened post-operatively. No death was found in this group.
CONCLUSIONSUsing epidural approach for clinoidal meningiomas and grinding anterior clinoid process was advantageous to block tumors base blood supply and detach infraclinoidal tumors from internal carotid artery. Supraorbital-pterional approach could minimize brain retraction and was advantageous to expose superior pole of giant tumors.

Most intrasellar meningiomas are located in the subdiaphragmatic and supraglandular region because they originate from the diaphragma sellae. Subglandular meningiomas located under the pituitary gland are extremely rare. Intrasellar meningiomas in the subdiaphragmatic and subglandular region probably originate from the dura in the sellar floor. We report a case of a subglandular meningioma along with a review of the literature.

OBJECTIVETo summary the microsurgical techniques for removal of huge tuberculum sellae meningiomas through the bi-subfrontal anterior longitudinal fission approach.
METHODSEleven patients with huge tuberculum sellae meningiomas underwent microsurgical removal of the meningiomas between January, 2005 and November, 2009. The microsurgical techniques were summarized, and the factors affecting the prognosis were analyzed.
RESULTSAmong all the patients, 5 had Simpson grade I meningioma removal and the other patients had Simpson grade II removal. No death occurred in these patients. Nine patients showed vision improvement after the surgery, one had no significant improvement, and the other one experienced worsening of vision. Transient postoperative diabetes insipidus occurred in 5 cases.
CONCLUSIONWith satisfactory exposure of Dorsum sellae, bottom of the third ventricle and cavernous sinus, the bi-subfrontal anterior longitudinal fission approach is suggested for treatment of tuberculum sellae meningiomas. The key to improve the GTR and reduce the complication lies in the sequence of the operation, namely resection of the tumoral basement before dissection of the potential arachnoidal space and tuberculum.

Objective: To summarize the experience of endoscopic endonasal approach in the treatment of anterior skull base with intra-extracranial extension meningioma, and to analyze the perioperative quality of life of patients, and to discuss the safety and efficacy of the treatment. Methods: A total of 83 cases of anterior skull base with intra-extracranial extension meningioma admitted to Xuanwu Hospital, Capital Medical University from October 2007 to October 2019, who underwent endoscopic endonasal approach tumor resection, were retrospectively analyzed. The quality of life of the patients were evaluated by Anterior Skull Base Questionnaire (ASBQ) before and after surgery. The surgical techniques, extent of tumor resection, postoperative complications and the changes of patients' quality of life were summarized and analyzed. SPSS 23.0 software was used for statistical analysis. Results: A total of 57 anterior skull base with intra-extracranial extension meningioma patients were enrolled according to the inclusion and exclusion criteria, including 23 males and 34 females, aging (48.6±16.6) years. Fifty cases (87.7%) reached or exceeded Simpson gradeⅠ resection, and 7 cases underwent subtotal resection. Symptoms relief was as follows: headache relief in 45/50 (90%), vision improvement in 18/19 (94.7%), olfaction improvement in 6/45 (13.3%), mental symptoms improvement in 3/9 (33.3%), and seizure relief in 5/7 (71.4%). Postoperative complication included mental symptoms in 5 cases, cerebrospinal fluid leakage in 2 cases, epilepsy in 2 cases, frontal lobe hemorrhage in 1 case, and intracranial infection in 1 case. The follow-up period was 38 to 144 months. There were two cases recurring and no death. ASBQ assessment showed significant improvement in general condition, physical function, role function, mood disorder, pain, vision impairment, and sleep disturbance at 1 month postoperatively, with continued improvement thereafter, and reached stable at 6 months postoperatively. Conclusion: Endoscopic endonasal approach surgery is able to achieve safe and effective tumor resection for anterior skull base intra-extracranial extension meningioma, and the quality of life of patients can be improved steadily.

BACKGROUNDSphenoid wing meningioma en plaque is a special morphological subgroup of intracranial meningiomas, defined by a carpet-like, soft tissue component that infiltrates the dura and invades the sphenoid wing and orbit associated with a significant hyperostosis. This report summarized our experiences in 37 patients with sphenoid wing meningioma en plaque who had been treated with transcranio-orbital approach surgery.
METHODSA retrospective study was made on clinical manifestations, neuroradiological features, and operative techniques in 37 patients undergoing transcranio-orbital approach from Sep. 1998 to Apr. 2009. Patients ages: 16 years to 67 years, 45.5 years in average; sex: 15 males, 22 females. Chief complaints were progressive proptosis and visual acuity deficits. All patients were operated on using a fronto-temporal approach with orbital decompression. The extent of tumor resection and postoperative complications were investigated.
RESULTSSimpson grade II resection was achieved in 9 patients, Simpson grade III in 22 patients and Simpson grade IV in 6 patients. Pathological examination showed 27 (73%) patients were meningothelial meningiomas. After surgery, proptosis improved in all patients, visual acuity improved in 18 patients (69%). Temporary ophthalmoplegia was found in 8 patients, cerebrospinal fluid leak was found in 1 patient. Duration of follow up was from 3 months to 9 years, tumor recurred in 7 patients, and 5 patients underwent second surgery, including two trans-nasal endoscopic surgeries to resect sphenoid sinus-involved tumor. There were no operation-related deaths or other significant complications.
CONCLUSIONSSphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are more likely to produce adjacent hyperostosis and have characteristic radiological appearances. All the hyperostosis bone of the great wing of sphenoid bone should be removed to prevent recurrence. Extensive tumor removal with bony decompression at the orbital apex can produce satisfactory cosmetic and functional outcome. Close co-operation between the neurosurgeons and the ophthalmologists is important.

BACKGROUNDAtypical meningioma accounts for about 4.7% to 7.2% of all kinds of meningiomas, which is invasive with a relatively high recurrence and mortality. The objective of this study was to investigate the clinical manifestations and therapeutic strategies of atypical meningioma.
METHODSA total of 74 patients who underwent surgical treatment and pathologically confirmed for atypical meningioma in Neurosurgery Department of Beijing Tiantan Hospital from January 2003 to December 2008 were enrolled in this study. The characteristics of the tumors as well as therapeutic regimens and follow-up data were reviewed. After surgery, 56 patients underwent radiotherapy. Patients were followed up for about 3.5 years (range, 0.5 - 6.0 years), and 58 patients completed follow-up.
RESULTSOf the 58 patients who completed follow-up, good recovery was found in 30, neurological dysfunction in 15, and death in 13. Of the 58 patients, 21 had recurrent meningioma and 18 underwent a second surgery.
CONCLUSIONSAtypical meningioma is difficult to manage, with a high recurrence rate and poor survival. The extent of tumor resection and histological grade are the key determinants of outcome. Radiation therapy can be used as an adjunctive treatment after total or partial resection.
