biostudies-literatureUnknown14da Silveira RL<h4>Background</h4>The management of foramen magnum meningiomas (FMMs) has been a challenge for skull base neurosurgeons. Since the initial description of a FMM in 1872, various surgical approaches have been described. Posterior and posterolateral FMMs are safely removed through a standard midline suboccipital approach. Nevertheless, we still face controversy regarding the management of anterior or anterolateral lesions.<h4>Case description</h4>A 47-year-old patient presented with progressive headaches, unsteadiness, and tremor. Magnetic resonance imaging showed an FMM that caused significant displacement of the brainstem.<h4>Conclusion</h4>This operative video highlights a safe and effective surgical technique for the resection of an anterior foramen magnum meningioma.Surgical neurology international56https://www.ebi.ac.uk/biostudies/studies/S-EPMC9990808biostudies-literatureForamen magnum meningioma approached by the midline subtonsilar approach - Revisiting Cushing's classification of craniospinal meningiomas.PMC9990808da Silveira RLVon Zuben DOBertani RLandeiro JAfalseForamen magnum meningioma approached by the midline subtonsilar approach - Revisiting Cushing's classification of craniospinal meningiomas.<h4>Background</h4>The management of foramen magnum meningiomas (FMMs) has been a challenge for skull base neurosurgeons.
