Metastases to the breast from small-cell lung cancer: MR findings. A case report.

We report a case of blood-borne metastatic breast disease of small-cell lung cancer in a 44-year-old patient with no previous history of malignancy. The possibilities of MR in the early detection of breast metastases and their appearance on MR images are discussed. Metastases to the breast should be considered when MR mammography of the breast reveals multiple, bilateral, well-defined lesions with ring enhancement and wash-out pattern.
