As clinical symptoms persisted, an ultrasound examination was performed which revealed a diffuse bilateral increase in echogenicity limited to the biceps brachii, brachialis, and brachioradialis muscles (Figure 1).
MRI of the right elbow (transversal T2w TSE) shows homogenous signal increase in the brachioradial (marked as *) and the brachial muscle (marked as +).

T2 TSE in the absence of other pathological signal alterations (Figure 2). The affected muscles showed normal signal intensity on T1-weighted images.
