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.
