Background: Ossification of the anterior longitudinal ligament (OALL) of the cervical spine is a relatively rare disease. If patients present with dysphagia, hoarseness, and/or dyspnea, they may require surgery.
Case Description: Over a 7-month period, a 55-year-old female with a history of cerebral palsy developed a progressive quadriparesis accompanied by diffuse sensory loss (i.e., clumsiness of the hand/legs and gait disturbance). The cervical spine X-rays showed atlanto-axial subluxation with instability, while the cervical MRI demonstrated "pseudotumor in the retro-odontoid" region. Following an occipital cervical fusion (C0-C2) surgery, her quadriparesis resolved. Nevertheless, she had persistent dysphagia that worsened over 6 months. Video fluoroscopy revealed severe mechanical stenosis of the pharynx, which was attributed to OALL extending from the C3-C6 levels. Following OALL resection through a right anterior approach utilizing diamond burrs and an ultrasonic bone curette, the dysphagia rapidly resolved.
Conclusion: We report a rare case of retro-odontoid pseudotumor successfully treated with a posterior C0-C2 cervical fusion. Additional symptomatic C3-C6 OALL, responsible for progressive dysphagia, was later managed with focal anterior OALL resection.

Article Synopsis
- Adenoid cystic carcinomas (AdCC) of salivary gland origin are primarily defined by the presence of specific gene fusions, notably MYB::NFIB and MYBL1::NFIB, with sinonasal AdCC being particularly aggressive and lacking effective treatments.
- Researchers conducted an extensive analysis of 88 sinonasal AdCC cases using various techniques like NGS and FISH to identify gene fusions and mutations, finding that the majority harbored canonical fusions while some had noncanonical ones, with a few tumors showing no fusions at all.
- Mutational analysis revealed that about 68% of AdCCs tested (21 out of 31) had mutations in key oncogenes, highlighting potential areas for targeted
