Does bone marrow edema induced by mechanical stress progress to structural lesions?

Credit: Scientific Abstracts (2024). DOI: 10.1136/annrheumdis-2024-eular.6091 Immediately after childbirth, a large number of women have sacroiliac bone marrow edema (BMO) visible on MRI. Although generally attributed to mechanical stress, these transient postpartum lesions bear a striking resemblance to the inflammatory lesions seen in axial spondyloarthritis (axSpA). BMO in the sacroiliac joint on MRI is present in up to 84% of people with non-radiographic axSpA—but it is also often seen in a non-inflammatory setting, such as in women after childbirth. As back pain is common after childbirth, differential diagnosis with axSpA Read More
