Background context: If a herniated lumbar disc fragment extrudes and migrates away from the spinal column, the radiographic appearances can be confusing.
Study design: In this article, we report a rare case of a sequestrated disc fragment in the psoas muscle, discrete from the adjacent disc space, which presented with features similar to a psoas abscess on imaging studies.
Conclusions: It is vital that in such cases the correct diagnosis is made to avoid unnecessary treatments and inappropriate management.
