What is DISH?
DISH stands for diffuse idiopathic skeletal hyperostosis (also known as Forestiers disease). DISH has many manifestations throughout the body, including calcification and ossification of ligamentous and tendinous insertion sites, particularly involving the pelvis and patellae (known as “whiskering”), enthesophyte formation on the calcanei and olecranon processes, and paraarticular osteophyte formation, particularly around the hip joints. Its most common manifestation is in the spine, however, where it is associated with calcification and ossification of the anterior longitudinal ligament and large bridging osteophytes anteriorly and laterally, sometimes interrupted by linear lucencies owing to herniation of intervertebral disc material. OPLL can occur in DISH as well
