Radiology of stromal sarcoma of the breast with ossifying pleural metastases

Abstract Stromal sarcoma of the breast is a rare tumour, the radiology of which has not been to our knowledge properly documented: the case presented returned to medical attention with a large, apparently calcifying pulmonary mass. This proved to be an ossifying pleural metastasis at thoracotomy, when a second smaller, unsuspected similar lesion was found. The radiological findings (including mammography and CT) are reviewed. The role of the radionuclide bone scan (the full significance of which was not appreciated preoperatively) is discussed.
