title: A variant of diffuse idiopathic skeletal hyperostosis: a case report.
abstract: The case of an elderly man with a bamboo-like spine is presented. Because the patient's osteoporosis prevented proper evaluation of the sacroiliac and apophyseal joints on plain radiographs, the case originally was misdiagnosed in an outpatient clinic as ankylosing spondylitis. A further work-up showed the integrity of the apophyseal and sacroiliac joints, as well as cortical hyperostosis of the midcervical spine consistent with the diagnosis of diffuse idiopathic skeletal hyperostosis (DISH).
