This portion of the dura mater is actually covering the lesser wing of the sphenoid bone from the anterior clinoid process (ACP) to the pterion.. The tumor is mainly locally destructive, and distant metastases are relatively rare. There is a significant difference in progression-free survival rates between spheno-orbital meningiomas and the two other groups. Conclusions: Maximal safe resection and postoperative stereotactic radiotherapy significantly reduced the recurrence rate of medial sphenoid wing meningiomas with infiltration of the cavernous sinus. The purpose of this study was to investigate prognostic . However, it is not clear whether the clinical outcome of this tumor is worse in children than in adults. Sphenoid wing en plaque meningiomas are a subgroup of meningiomas defined by its particular sheet-like dural involvement and its disproportionately large bone hyperostosis. Meningiomas account for 15 to 20% of intracranial tumors and 90 percent of meningiomas are intracranial. The 5 year recurrence free survival for WHO Grade I meningiomas is 88%.

The five-year survival rates for meningioma are as follows: Grade I tumor: 95.7%. OBJECTIVE Hyperostosing sphenoid wing meningiomas cause bony hyperostosis that may extend into the orbit, resulting in proptosis, restriction of extraocular movements, and/or compressive optic neuropathy. The majority of meningiomas are benign and patients are typically considered surgically cured once tumor resection is complete. They commonly occur in the fourth through sixth decades of life. . The tumors are most common in older patients, with the highest rate in people in their 70s and 80s. These tumors can cause visual problems, loss of sensation in the face, or facial numbness.

A 36-year-old male presented with a very rare epidermoid tumor in the sphenoid sinus manifesting as paresis of the right sixth cranial nerve and diplopia. Group 1 meningiomas present a more favorable subgroup with fortunate visual outcome and radical removal is limited because of cavernous sinus infiltration, with consequential higher recurrence rates in Group 2 tumors. They were classified into Group 1 (without cavernous sinus involvement) and Group 2 (with . METHODS: Among 256 sphenoid wing meningiomas, there were 108 medial sphenoid wing meningiomas of globoid shape. It helps explain the number of people who are diagnosed with meningioma and general survival rates. Recurrence/regrowth rates were also analyzed. The figures listed above are given in 1, 2, 5 and 10 year intervals simply because doctors use these intervals for research/measuring purposes - they are not meant to represent how long a person will live .

Approximately ~15-20% of all meningiomas arise from the sphenoid wing, with about half of these arising from the medial portion of the wing. The prognosis of patients with anaplastic meningioma is generally poor, mainly because of aggressive growth. Introduction: Predictors of survival and progression of disease in atypical meningiomas are less well documented in the literature compared to benign meningiomas. Europe PMC. A meningioma can vary in size from a few millimeters to many centimeters in diameter. Medial sphenoid wing meningiomas are a heterogeneous group of tumors originating from the anterior clinoid and the medial third of the lesser . Progression-free survival was also significantly prolonged after postoperative radiotherapy (p-value = 0.0002). In a study of 755 cases, Orton et al found that the 5-year overall survival rate of patients with anaplastic meningioma was 41.4 Total surgical resection is difficult and therefore these tumors have high recurrence rates. This application is a National Stage application of International Application No. Spinal Meningioma: Located in the spine, in some cases against the spinal cord. The 5-year survival rates of this type of brain tumor can provide you an estimate of the percentage of people who live at least 5 years after being diagnosed with a meningioma.

Menu. In case of the latter, a complete resection may not be achievable. A higher 3-year overall survival was associated with grade 1 and 2. This type makes up 20% of meningiomas. It is found that performing a maximal safe resection is the factor most strongly associated with a lower recurrence rate in patients with medial sphenoid meningioma infiltrating the cavernous sinus, and that postoperative stereotactic radiotherapy of the residual tumor also significantly prolongs PFS. Sphenoid Meningioma: Located near the sphenoid bone behind the eyes. The extent of bony removal necessary and the optimal reconstruction strategy to prevent enophthalmos is debated. Approximately 20 percent of meningiomas are sphenoid wing. About. However, there are very few publications about the long-term disease-free survival rates and monitorization of the neurological abnormalities, radiological findings, and toxicity 10). The rate of tumor site appearance and their percentages of recurrence are given in Table 3. The histologic appearance is characteristic. Outcomes are especially positive for . [Show full abstract] recurrence/progression and progression-free survival (PFS) rates of atypical meningioma, particularly focused on the role of postoperative adjuvant radiotherapy. An accurate classification of global medial sphenoid ridge meningiomas is mandatory to gain insight into their clinical behavior and for understanding the long-term efficacy and safety of available treatment options. . The extent of surgical resection and histological grade are very important prognostic factors. 30-37.
