Hydatid bone disease is very rare, accounting for only 0.5%-4% of all the cases of hydatidosis. Moreover, bone hydatidosis is difficult to diagnose correctly using preoperative imaging methods. Recently, we used ultrasonography to evaluate one patient with hydatid disease in the sternoclavicular joint, which was infected by the larvae of Echinococcus multilocularis. The main ultrasonographic findings were as follows: multilocular cystic formation, calcification, and bone destruction. We think that ultrasonography is one of the useful diagnostic aids for cases having osseous lesions.
