title: Diffuse skeletal hyperostosis in idiopathic hypoparathyroidism.
abstract: A case of idiopathic hypoparathyroidism (IHP) is reported with extensive ligamentous and tendinous ossification and soft tissue calcification. The pertinent radiological features of IHP and the unusual findings in this case are reviewed together with similar previously reported cases. Whether IHP is a causative or aggravating factor in the aetiology of the skeletal changes is discussed with particular reference to their similarity to diffuse idiopathic skeletal hyperostosis (DISH). We conclude that, in patients with an ossifying diathesis, IHP acts as a stimulant resulting in exuberant skeletal hyperostosis that is indistinguishable from DISH.
