We report a case of cervical ossification of the anterior longitudinal ligament(OALL) that contributed to dysphagia with ossification of posterior longitudinal ligament. A 63-year-old man complained of progressive dysphagia for solid foods. Clinical and radiographical findings including barium esophagogram and computed tomography showed OALL in cervical vertebrae from C2 to C7. Magnetic resonance images demonstrated displacement of the trachea and esophagus by OALL. The patient underwent anterior ostectomy from C2 to C7 via anterior cervical approach with excellent relief of dysphagia.
