Progressive Paralysis of the Right Lower Extremity due to Diffuse Idiopathic Skeletal Hyperostosis: A Case Report

ABSTRACT

Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease, is a common disorder characterized by ossification and calcification of soft tissues such as the enthuses and joint capsules, particularly affecting the spine. This condition affects approximately 3~30% of men older than 50 years of age. We present the case of a 39-year-old woman diagnosed with DISH combined with extensive ossification of the posterior longitudinal ligament (OPLL) and ossification of ligamentum flavum (OLF). The emergency physician should understand the typical radiologic findings associated with DISH and its clinical presentations in order to diagnose and treat this problem.
