[Diffuse idiopathic skeletal hyperostosis as a cause of dysphagia].

Radiographic, clinical and pathologic abnormalities of diffuse idiopathic skeletal hyperostosis (DISH) are presented. Definite criteria must be fulfilled to differentiate DISH from other diseases of the spine, especially intervertebral osteochondrosis and ankylosing spondylitis. A case of massive DISH in the cervical spine causing dysphagia is described.
