Melorheostosis with an associated para-articular enhancing soft tissue mass

Published:February 02, 2019DOI:https://doi.org/10.1016/j.clinimag.2019.02.001

      Highlights

      • Meloheostosis is a rare bone dysplasia which may also cause associated soft tissue changes.
      • MRI appearance of the soft tissue component is variable and depends on the histologic constituents.
      • This report emphasizes an enhancing soft tissue component which can mimic sarcoma.
      • Knowledge of the variable appearance can prevent misdiagnosis and unnecessary workup.

      Abstract

      Melorheostosis is a rare non-hereditary sclerosing bone dysplasia which predominantly affects the appendicular skeleton. Although melorheostosis is typically recognized as an osseous lesion, associated soft-tissue components have been reported. Advanced imaging with MRI may allow for more complete evaluation of these soft tissue components; however, there is little information regarding their MRI characteristics which may lead to confusion with malignant processes. We present a case of melorheostosis in a 32-year-old woman with an associated paraarticular enhancing soft tissue mass and emphasize discriminating this from soft tissue sarcoma.
