What does the acronym DISH stand for?

• A. Diffuse idiopathic skeletal hyperostosis
• B. Diffuse inflammatory skeletal hyperostosis
• C. Diffuse idiopathic synovial hyperostosis
• D. Diffuse inflammatory syndesmophyte hyperostosis

Answer: (A)

DISH stands for Diffuse idiopathic skeletal hyperostosis. This name reflects a widespread, noninflammatory bone overgrowth along the spine: “diffuse” means widespread, “idiopathic” indicates no identifiable inflammatory cause, “skeletal” points to bone, and “hyperostosis” means excessive bone formation. Clinically it appears in older adults and is best recognized radiographically by flowing anterior osteophytes that span multiple contiguous vertebrae, with preserved disc spaces and no sacroiliac inflammation. This noninflammatory, skeletal pattern distinguishes it from inflammatory spine diseases such as ankylosing spondylitis, which is why this expansion is the correct one.
