Diffuse idiopathic skeletal hyperostosis (DISH) is a common skeletal disease of unknown aetiology. This article discusses how radiographic abnormalities are used to diagnose patients with DISH.
Diffuse idiopathic skeletal hyperostosis (DISH) is a common skeletal disease of unknown aetiology and is characterised by ligamentous ossification of the anterolateral spine. Forestier and Rots-Querol first reported this condition in a series of patients in 1948 and later named it senile ankylosing hyperostosis of the spine. It was apparent that it differed from ankylosing spondylitis and vertebral spondylosis. Over subsequent years it was also referred to as ankylosing vertebral hyperostosis and Forestier’s disease. In 1975, Resnick proposed the name diffuse idiopathic skeletal hyperostosis.
