There are three well-defined fusiform masses along the course of the radial nerve (12 x 10 x 8 mm), median nerve (16 x 11 x 9 mm) and ulnar nerve (16 x 11 x 7 mm). They elicit an isosignal to the muscles on T1, high signal on T2 and STIR with moderate peripheral enhancement.

Case Discussion
MRI features are most consistent with stump neuromas arising from the end of the radial, median, and ulnar nerves.
