Myositis ossificans is caused after muscular strains and trauma usually seen in aggressive sports players such as American football players. Return to activity before complete healing of muscle strains has been deemed the reason why these muscles get ossified.
If they don't show the X ray they will probably say this in the question stem "Flocculent radiodensities surrounding a radiolucent central area".
It's important to differentiate this simple myositis ossificans from the more severe genetic disease called Fibrodysplasia Ossificans Progressiva see this emedicine article.
