Bilateral hypoglossal nerve injury with occipital condylar fracture.
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.


CONCLUSIONS
Condylar fracture may cause twelfth nerve palsy by injuring the central or peripheral nerve.
