A retrospective review was conducted to determine the effect sonography has in localizing these foreign bodies. Patients selected for this study included all cases in which sonography was performed and demonstrated the presence or assisted in the removal of FB. After review of the records, 20 patients fit this selection criterion. Seventeen of the 20 patients had radiographs performed, in which only 8 of the 17 were positive for FB. Sonography demonstrated all FB in 19 of 20. In 11 of 20 patients, sonographic imaging directly guided their removal. Sonography can be an invaluable tool in finding and localizing for removal soft tissue foreign bodies.
