What causes Romanus lesion?
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 1.
What is inflammatory Spondyloarthropathy?
Inflammatory spondyloarthropathy, also known as spondyloarthritis, is an autoimmune disease. It occurs when the immune system attacks the spine and sometimes the joints of the arms and legs.

An inflammatory lesion in the vertebral body is defined as increased signal in the bone marrow on STIR or T2-weighted, fat-suppressed sequences, where the bone marrow signal in the center of the vertebra, if normal, constitutes the reference for designation of normal signal.
Does ankylosing spondylitis affect bone marrow?

What is a shiny corner lesion?
Healing response to these inflammatory erosions appears radiographically as reactive sclerosis in the same location, which is known as the shiny corner sign 3 . Ragnar Romanus, a Swedish general surgeon, and Sven Yden, a Swedish radiologist, described this eponymous lesion in a paper in 1955.
What are active Romanus and Andersson lesions in ankylosing spondylitis?
Active Romanus and Andersson lesions in a patient with ankylosing spondylitis. Andersson lesion, also known as rheumatic spondylodiscitis, is defined as an inflammatory non-infectious condition involving the intervertebral discs by spondyloarthritis. It occurs in about 8% of patients with ankylosing spondylitis.
