Abstract
OBJECTIVE: To analyze the imaging characteristics of histologically diagnosed metastases to the breast. MATERIAL AND METHODS: We selected patients histologically diagnosed with metastases to the breast in our diagnostic and interventional breast imaging unit between March 2010 and September 2018. RESULTS: A total of 9 patients (all women; mean age, 60 y; age range, 28-89 y) were diagnosed with metastases to the breast. In 1 (11.11%) case, the primary disease was diagnosed from the breast lesion. The primary tumors were melanoma (n=5), neuroendocrine tumor (n=2, one from the small bowel and one from the cervix), lung adenocarcinoma (n=1), and ovarian cancer (n=1). The clinical and imaging manifestations depend on the type of dissemination of disease and can simulate benign and malignant primary breast lesions. CONCLUSION: There is no specific imaging pattern for metastases to the breast that would help to orient the diagnosis. It is important to consider this etiological possibility if the patient has a history of a primary tumor in another organ.
