Cervical MRI demonstrated an extramedullary intradural tumor in anterior part of foramen magnum.C1-2 Posterior midline suboccipital laminectomy with spinal cord decompression was performed. After surgery, her symptoms improved. Histopathological evaluation revealed schwannoma. Symptoms of foramen magnum syndrome are various and Conclusion: Nonspecific, so diagnosis requires a high suspicious in early stages, when tumor resection may lead to significant improvement of the patients.
