The Romanus lesion represents an early finding in inflammatory spondyloarthropathies, such as ankylosing spondylitis and enteropathic arthritis, and appears as irregularity and erosion involving the anterior and posterior edges of the vertebral endplates . Healing response to these inflammatory erosions appears radiographically as reactive sclerosis, which is known as the shiny corner sign.
History and etymology
Ragnar Romanus, a Swedish general surgeon, and Sven Yden, a Swedish radiologist, described this eponymous lesion in a paper in 1955. This paper was also the first to use the term shiny corners .
