Abstract

BACKGROUND

Os odontoideum is a rare abnormality of the upper cervical spine, and os odontoideum associated with a retro-odontoid cyst has been described as a marker of local instability.

CASE DESCRIPTION

This paper reports a case of a 52-year-old female patient who was diagnosed with os odontoideum associated with a retro-odontoid cyst. The patient underwent posterior C1-C3 fixation without surgical removal of the cyst. Magnetic resonance imaging (MRI) two days later revealed that the retro-odontoid cyst was still present and that there were no significant changes to it when compared with the preoperative MRI.

CONCLUSION

Retro-odontoid cysts associated with unstable os odontoideum can lead to symptomatic spinal cord compression. Posterior C1-C3 fixation can restore atlantoaxial stability by allowing the gradual resorption of the cyst and ensuring spinal cord decompression. Fixation can also avoid the surgical risk associated with a high-riding vertebral artery.

摘要

背景

齿突小骨是上颈椎的一种罕见异常，与齿突后囊肿相关的齿突小骨被描述为局部不稳定的一个标志。

病例描述

本文报告一例52岁女性患者，该患者被诊断为与齿突后囊肿相关的齿突小骨。患者接受了C1-C3后路固定术，未手术切除囊肿。两天后的磁共振成像（MRI）显示齿突后囊肿仍然存在，与术前MRI相比无明显变化。

结论

与不稳定齿突小骨相关的齿突后囊肿可导致有症状的脊髓压迫。C1-C3后路固定术可通过使囊肿逐渐吸收并确保脊髓减压来恢复寰枢椎稳定性。固定术还可避免与高位椎动脉相关的手术风险。
