Romanus lesion explained

In radiology, a Romanus lesion is the erosion of the anterior and posterior vertebral endplates in patients with an inflammatory spondyloarthropathy – such as ankylosing spondylitis or an enteropathic arthropathy.[1] [2] The anterior erosion in particular causes a loss of anterior vertebral body concavity, causing the vertebra to display a squared contour or even a barrel-shape. Healing of the erosion results in a sclerotic increase in density causing what is known as a shiny corner sign,[3] which can later result in syndesmophyte formation.[4] It is most easily diagnosed using MRI, compared to conventional radiography.

This type of erosion was initially described by Ragnar Romanus and Sven Ydén in a paper published in 1952.[5]
