“…T he prevalence of resected pathologically confirmed meningioma in the United States is 0.000975 and FMM is only 1.8 to 3.2% of all types of meningiomas; it means that the approximate prevalence of diagnosed FMM is 2.5 in 100,000 of the normal population 6,7 . The foramen magnum, at the junction of cranium to cervical spine, contains some important structures, including lower cranial nerves (IX, X, XI, and XII nerves), vertebral arteries, and brainstem.…”

Case: Meningioma is the second most common intracranial tumor. We present 2 cases of foramen magnum meningioma (FMM) that was first operated on with the diagnosis of carpal tunnel syndrome (CTS). Conclusion: During the diagnostic assessment of CTS and recalcitrant CTS, a more proximal etiology of nerve compression should be considered, including FMM. If a more proximal cause of nerve dysfunction is suspected, cervical spine magnetic resonance imaging may be beneficial to evaluate a patient for spinal etiology.

“…10 FMM management needs a comprehensive anatomical knowledge, due to many neural and vascular structures in FM. 4,11,12 The neural structures involved are lower cranial nerves (CN IX-XII), upper cervical nerves (C1 and C2), cerebellar tonsils, inferior vermis, fourth ventricle, medulla, and spinal cord. 4,7 Major arterial structures within FM are vertebral arteries (VA), posterior inferior cerebellar arteries (PICAs), anterior and posterior spinal arteries, and the meningeal branches of vertebral, external, and internal carotid arteries.…”

Introduction: Foramen magnum meningiomas (FMMs) arise from meningothelial cells of arachnoid layer in the craniospinal junction. FMMs are rare and comprise only 1.8 to 3.2% of all meningiomas. Patients with FMMs generally have vague symptoms and are often misdiagnosed. Surgical management of FMMs poses a challenge because foramen magnum is a highly complex territory of the skull base and contains many important and vital structures. Up until this date, the surgical approaches for FMMs that arise anterolaterally remain varied. We aimed to present a case of anterolateral FMM that was successfully managed through posterior suboccipital midline approach. Case presentation: A 49-year-old female presented with chief complaint of tetra paresis for the past 4 months. Initially, she was experiencing tingling and numbness on her right neck radiating to her right hand. Her symptoms were worsened, radiating to all of her four extremities along with progressive motor weakness that made her unable to walk. Whole spine MRI was performed and anterior meningioma extending to the right side at the level of foramen magnum was found. The posterior suboccipital midline approach with C1 laminectomy and C2 partial superior laminectomy was performed. The patient made a good recovery immediately after the surgery and there was no recurrence of her symptoms during 4 months follow-up. Conclusion: Surgical approaches for FMM remain varied according to several studies. However, the surgical strategy should be patient-tailored to achieve the maximal resection and prevent morbidity. As for our case, posterior suboccipital midline approach is safe and feasible surgical procedure to treat anterolateral FMM.

“…Meningiomas may present with a wide array of symptoms dependent upon their size, location, and associated presence of vasogenic edema. Foramen magnum meningiomas represent a common histological tumor in a rare and eloquent location [4]. Surgery and more recently radiation therapy have been cornerstone treatments for meningiomas of all grades.…”

Meningiomas are tumors that originate from the meningeal or dural cover of the brain and are the most common primary benign brain tumors. Currently, the accepted management of these tumors is attempted total surgical excision when technically possible and associated with an acceptable risk. However, radiation therapy has been shown to provide excellent local control when used either as an adjunct to surgery or as a primary treatment. We present a case report of a 46-year-old female patient with an unresectable left foramen magnum meningioma resulting in headaches, neck pain, and swallowing difficulty. The patient underwent CyberKnife (Accuray Incorporated, Sunnyvale, CA) radiosurgery to a dose of 3,000 cGy in five fractions in March 2011. The patient tolerated treatment without complications and has remained clinically well with no ongoing cranial nerve deficits as of the last examination in late 2019. This demonstrates the excellent local control obtained when using radiosurgery as both a surgical adjunct and a primary treatment for meningiomas.
