69F shoulder pain with surface bone lesion XR and MRI, please help


There is scalloping of the outer cortex of the proximal humerus with adjacent mineralization (XR from yesterday)

She has a tear at the anterior supraspinatus insertion and enhancing bursal inflammation which I presume is responsible for her pain.

It seems that the surface chondroid lesion has been living with her for a long while, as there is smooth erosion of the outer cortex.
I think the imaging features are those of a periosteal chondroma, but I wonder if there is any possibility of chondrosarcoma.
Should this be referred for orthopedic oncologic consultation?

Thank you.

Hilary
