Abstract

The term 'craniovertebral junction' refers to the occipital bone that surrounds the foramen magnum and the atlas and the axis vertebrae. A wide variety of congenital, developmental, and acquired anomalies exist at the craniovertebral junction. The authors present a rare case of the congenital anomaly of the craniovertebral junction consisting of atlantal hypoplasia, atlantal assimilation, and basilar invagination in a 58-year-old male. An occiput-C2 arthrodesis was performed. The clinical and imaging features are described, and the embryology and etiology of this anomaly are discussed.
