Bilateral hypoglossal nerve injury with occipital condylar fracture

Abstract

Background: A 20-year-old woman with a right occipital condylar fracture and bilateral hypoglossal nerve injury is presented. Only 17 cases of condylar fracture have been reported in the literature. Methods: The patient was evaluated with plain films, coronal and axial cut CT, and MRI. Results: MRI showed a severely distorted but otherwise normal medulla and a displaced condylar bone fragment. Conclusion: Condylar fracture may cause twelfth nerve palsy by injuring the central or peripheral nerve.
