case_images: 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).
case_images: MRI of the right elbow (transversal T2w TSE) shows homogenous signal increase in the brachioradial (marked as *) and the brachial muscle (marked as +).

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