Abstract

The inferior accessory ossicle of the anterior arch of the atlas is quite rare and has been described in the literature by only few articles. However, these articles have only included plain radiographs in the description. In our case, the above ossicle is illustrated in two imaging modalities, plain radiography and CT imaging. The importance of this ossicle lies in its recognition as only an anatomical variant and not to be confused with other pathological conditions such as a fracture.
