Case: A 47-year-old Japanese woman with a medical history of xanthoma disseminatum (XD) presented with posterior neck pain and abnormal gait without a history of trauma. Imaging studies revealed odontoid process thinning resulting in its fracture due to XD involvement in the atlantoaxial joint and subsequent cervical myelopathy. Posterior C1-C2 fusion surgery improved the patient's symptoms. An XD lesion around the odontoid process was confirmed intraoperatively. Conclusion: We report cervical myelopathy caused by XD involvement in the C1-C2 joint, showing that early fusion surgery is critical for treating pathological fractures in patients with XD.
