55-year-old woman with secondary tumoral calcinosis. Erect AP radiograph of right humerus shows well-demarcated lobulated masses containing layering milk of calcium about right elbow, shoulder, and chest wall.

The masses were well-demarcated, lobulated and contained layering "milk of calcium" characteristic of tumoral calcinosis (Figure 1).
55-year-old woman with secondary tumoral calcinosis. (A-B) Axial CT images of the right upper extremity show lobulated soft tissue masses with multiple fluid-calcium levels. Note cortical destruction of the proximal humerus by tumoral calcinosis with extension into the intramedullary cavity. (C) Coronal CT image of the right upper extremity shows lobulated soft tissue masses with fluid-calcium levels. Note cortical destruction of the proximal humerus by tumoral calcinosis with extension into the intramedullary cavity.

The intramedullary calcifications contained multiple fluid-calcium levels (Figure 2, Figure 3).

There was cortical erosion of anterolateral second rib by the calcified mass (Figure 4A, Figure 4B).

T1-weighted and T2-weighted sequences. The characteristic fluid-calcium levels were seen with the fluid layer appearing isointense on T1-weighted and hyperintense on T2-weighted sequences and the "milk of calcium" layer appearing hypointense on T1-weighted and T2-weighted sequences (Figure 5).
