Diffuse Idiopathic Skeletal Hyperostosis and Ankylosing Spondylitis. Comment on the article by Latourte et al.

We read with great interest the article by Latourte et al about axial spondyloarthritis (SpA) like imaging in Diffuse Idiopathic Skeletal Hyperostosis (DISH) (1). On the spine magnetic resonance imaging, 76.9% of their cohort of patients with symptomatic DISH had at least 1 inflammatory lesion, as assessed by bone medullar edema (BME). As soft tissue edema, BME may be caused by mechanical stress or by inflammation (2). Mechanical stress is implicated in the pathogenesis of DISH. This article is protected by copyright.
