romanus lesion

Spinal

disorders mimicking infection. 32-year-old male admitted for exacerbation of back pain and inflammatory markers. T1 (a), T2WI (b), and STIR- R1 point 7 (c) show inflammatory endplate changes at the L3–L4 level mimicking a Schmorl node (arrow). Note that nuclear cleft sign is preserved (star). Enhancement in T1 fat-suppressed sequence after contrast (d) without disc enhancement or inflammatory paraspinal tissue. The same pattern is seen in the D11–D12 disc space (long arrow), associated with Romanus feature R1 point 8 at L5 body margin (short arrow)

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 .
