A case in which ultrasonography was useful in differentiating between rib fracture due to compression after biopsy and rib metastasis of breast cancer

At her previous hospital, the ultrasound revealed a mass in the outer right breast, which was later diagnosed as breast cancer (apocrine carcinoma) via ultrasound-guided core needle biopsy. Recent advances in ultrasound technology have enabled the acquisition of images with higher contrast and resolution, even of deep lesions such as ribs [4], which is expected to improve the detection of fracture sites. Since ultrasound can be used to evaluate fractures in real time while also confirming the patient’s pain site, it may be beneficial to use ultrasound to evaluate bone in patients who complain of chest pain after a breast biopsy, as in this case.
