To determine the characteristics and regularity of multi-detector CT (MDCT) in breast cancer with skeletal thorax metastasis, we retrospectively analyzed the imaging findings of MDCT in 72 cases of breast cancer with bone metastasis before treatment. There were totally 455 metastasis involved sites. The most common metastatic site was thoracic vertebra. And the fourth left rib was most common lesion in rib metastasis. Right breast cancer was more likely to take place at the bilateral ribs (65%) and pectoral girdle (54.5%) metastasis. The lesions in 28 cases demonstrated osteolytic destruction (38.9%), while 30 cases showed osteogenic appearance (41.7%). In conclusion, the development of breast cancer with skeletal thorax metastasis has certain characteristics and regularity.
