DISH or Diffuse Idiopathic Skeletal Hyperostosis, aka Forestier disease, is a common disorder of unknown etiology, characterized by intermittent pain and stiffness in the involved spine segments. Spinal involvement of DISH characteristically produces flowing type ossifications in the anterolateral margins of the at least 4 contiguous vertebrae. This ossification can be of variable thickness, can measure up to 2cm.
The above images shows prominent ossifications in relation to the anterior aspects of C3 to C7 levels, with C4 to C7 appearing continuous. This is also causing mass effect on the hypopharyngeal soft tissue / pharyngo-esophageal junction.
