This is a 19-years old boy with pain that comes in the low back while playing football.
The MRI shows Schmorl’s nodes along the inferior end-plates of L1 and L2, which we would have dismissed off as non-significant.
A screening through the SI joints tells a different story. There is bilateral erosive sacroilitis with asymmetric marrow edema, consistent with seronegative spondyloarthropathy likely ankylosing spondylitis.
In this context, the Schmor’s nodes actually represent acute inflammatory spondylitis as part of the seronegative spondyloarthropathy.
