Meningiomas of the Foramen Magnum

Journal of Neurosurgery, 1963
M ENINGIOMAS arising at the foramen magnum produce a clinical syndrome which may be difficult to distinguish from other lesions of this region which are less amenable to therapy. The radiologic diagnosis of these tumors, by which a definitive diagnosis can be made, has received heretofore only brief attention in the literature.

Key Aspects in Foramen Magnum Meningiomas: From Old Neuroanatomical Conceptions to Current Far Lateral Neurosurgical Intervention

World Neurosurgery, 2017
7 p.Foramen magnum meningiomas represent a challenge for neurosurgeons. These tumors require careful surgical manipulation as they are often located in proximity to critical neurovascular structures and the cranial nerves.

Ventral foramen magnum meningiomas

Journal of Neurosurgery: Spine, 2000
Object. Ventral foramen magnum meningiomas (VFMMs) are rare lesions that account for more than 3% of all meningiomas. These are among the most challenging of all meningiomas to treat. The authors comprehensively analyzed multiple features in a series of VFMMs. Methods.

Benign tumors of the foramen magnum

Journal of Neurosurgery, 1984
✓ The authors reviewed 102 documented cases of benign extramedullary tumors of the foramen magnum treated at their institution between 1924 and 1982. There was 78 meningiomas, 23 neurofibromas, and one teratoma. Approximately 40% of the patients had a normal neurological examination upon first evaluation.

The Myelography Examination of the Foramen Magnum

Radiology, 1958
The clinical diagnosis of benign tumors in the region of the foramen magnum is often extremely difficult (2, 5, 8). Even if such a lesion is suspected, a satisfactory diagnosis may not be possible without roentgenologic evidence. In the presence of extradural malignant lesions, bone changes are generally detectable. The benign intradural tumors usually

No to shinkei = Brain and nerve, 1984
The clinical appearance of foramen magnum tumor is protean and, even at the stage when serious neurological deficits are present, the lesions are often misdiagnosed as another disease, especially cervical spondylosis and multiple sclerosis, and patients may undergo improper concervative or even surgical treatments.
