Abstract
BACKGROUND: The accessory nerve schwannoma localized in spinal canal is extremely rare; only nine cases have been reported in the literature until now. We report a new case of schwannoma at the spinal root of accessory nerve. OBSERVATION: A young woman aged 30 had a high cervical spinal cord compression with respiratory problems. At admission, magnetic resonance imaging (MRI) showed a tumor compressing the spinal cord at C2 to the foramen magnum. The tumor was removed successfully and its origin from the left accessory nerve was confirmed peroperatively. CONCLUSION: Although schwannoma of the accessory nerve is exceptional, this entity should be considered as a differential diagnosis with the other tumors of the foramen magnum.
