case_images: Single sonographic image with color Doppler of the left sternoclavicular joint demonstrates a circumscribed, avascular, cystic mass with a narrow neck that dives into the sternoclavicular joint. This connection with the joint is typical for ganglia.

case_images: Ultrasound imaging was performed which demonstrated a 6 x 4 x 4 mm irregular anechoic, thin-walled structure, without internal color Doppler signal, and with increased through transmission consistent with a cyst which demonstrated a narrow neck diving deep into the left sternoclavicular joint (Figure 1).
case_images: Single sonographic image of the right and left sternoclavicular joints shows a circumscribed, round, cystic mass with increased through transmission located just anterior to the left sternoclavicular joint.
