This report presents the clinical feature, surgical experience, prognosis and pathogenesis of cavernous malformation originated spinal accessory nerve. 45-year-old woman presented with a several-day history of headache and tingling sensation in the left arm and leg. A 1.7-cm heterogeneous, solid mass was found in the right side of the foramen magnum. It was removed by suboccipital craniotomy and C1 total laminectomy with a diagnosis of accessory nerve schwannoma. Histologic confirmation was compatible with cavernous malformation. Cavernous malformation involving the spinal accessory nerve on foramen magnum level is a rare disease which requires differential diagnosis from the more common nerve sheath tumor or meningioma. |
