Clinical Presentation of Foramen Magnum Meningioma Masqueraded by Carpal Tunnel Syndrome

Abstract

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.

Foramen magnum meningioma presented as cervical myelopathy in a pregnant COVID-19 patient: A case report

“…However, foramen magnum meningioma is often misdiagnosed. Bahrami et al reported 2 cases of foramen magnum meningioma mistaken for carpal tunnel syndrome due to the similarity of symptoms [ 8 ]. Some reported cases of foramen magnum meningioma presented as occipital neuralgia, drop attacks, brainstem compression, and cervical myelopathy [ 5 , [9] , [10] , [11] ].…”
