Diffuse idiopathic skeletal hyperostosis. Sagittal (a) noncontrast CT image of the cervical spine demonstrating large anteriorly flowing osteophytes extending from the C3–C7 levels without significant disc height loss consistent with the diagnosis of diffuse idiopathic skeletal hyperostosis (DISH). Lateral (b) fluoroscopy during a pharyngogram demonstrates posterior compression (arrow) of the cervical esophagus during swallowing
