We describe a case of the rare entity of a persistent ossicle on the top of the odontoid process. In a short review of the literature, we show developmental abnormalities of the odontoid process and its etiologies. The terminal ossicle (Bergmann) plays an important role in the differential diagnosis of a fracture of the odontoid process type I in adults using the classification of Anderson and D'Alonzo. If fracture and instability is excluded by plain radiographs, computed tomography and/or MRI, there is no need for additional therapy.
我们描述了一例齿突顶端存在持续性小骨这一罕见实体的病例。在对文献的简短回顾中，我们展示了齿突的发育异常及其病因。使用安德森和达隆佐的分类法，终末小骨（伯格曼小骨）在成人I型齿突骨折的鉴别诊断中起着重要作用。如果通过X线平片、计算机断层扫描和/或磁共振成像排除了骨折和不稳定情况，则无需额外治疗。
