Figure 11a. Subtle radiographic findings. (a) Frontal radiograph of the right humerus in a 42-year-old man reveals a subtle permeative appearance of the proximal third of the bone. (b) Anterior view of a whole-body bone scan shows diffuse uptake involving almost the entire proximal half of the right humerus. (c, d) Coronal T1-weighted (488/14) (c) and STIR T2-weighted (3,400/70) (d) images show that the lesion is associated with a small soft-tissue mass, which is best seen on the STIR image (arrows).
