Diffuse idiopathic skeletal hyperostosis (DISH) is a rheumatologic disease with unknown etiology characterized with ossifications of
columna vertebralis. Signs and symptoms include stiffness, pain and movement limitation of spine. The radiographic diagnostic
criteria in the spine include osseous bridging along the anterolateral aspect of at least four vertebral bodies, relative
sparing of intervertebral disc heights with minimal or absent disc degeneration, and absence of apophyseal joint ankylosis
and sacroiliac sclerosis. The diagnosis of DISH can be confused with ankylosing spondylitis (AS) because of some common clinical
and radiological characteristics. In this paper a diffuse idiopathic skeletal hyperostosis case misdiagnosed as ankylosing spondylitis
is reported.
