Thorax CT, mediastinal window, axial plane. Thickening and hypodense infiltration of right dorsal muscles. Notice small pleomorphic calcification.

Poorly defined margins suggested infiltration of the surrounding muscles which made a diagnosis of malignancy more feasible (Figure 1).
Abdominal MRI. DWI, b-value 50 (A) and BLADE sequence, T2W, fat saturation (B). Infiltration is visible on both sides in the dorsal region. Notice that the margins of hyperintense infiltration reache farther in peripheral direction on DWI images than on BLADE images.

Only on DWI sequences it was evidently noticeable that those small pathological foci were a part of a large infiltrating mass (Figure 2).
Ultrasound elastography of the right axillar area. A B-mode image reveals a large heterogeneous hypoechoic mass between the surrounding muscles. Elastography reveals increased stiffness in comparison to the surrounding tissue - the mass is about ten times harder than the reference muscle (red arrow).

However, elastography revealed visibly higher stiffness of the mass in comparison to uninvolved tissues (Figure 3).
