Occipital neuralgia secondary to exuberant callus formation. Case report.

The authors report the case of a 78-year-old woman suffering from right occipital neuralgia in whom computerized tomography and magnetic resonance images demonstrated an irregular bone mass in the C-2 vertebral body. This "bone tumor" happened to be an exuberant callus formation that arose as a result of a previous axis body fracture. The patient's occipital pain was immediately relieved after she underwent C2-3 root release.
