Despite the high rate of lung cancer among other primary tumors, metastasis of this common malignancy to the breast is very rare. We report 3 new cases of
lung cancer with breast metastases and discuss radiological and clinical findings. Radiologically each case displayed different features. First one of them had
bilateral superficially and deeply located irregular lesions. The second patient presented with findings similar to inflammatory breast cancer. The third case
had a circumscribed mass, resembling a benign complicated cyst. Radiologists should be aware of the spectrum of typical and atypical imaging findings of
metastatic involvement of the breast to guide the clinicians for appropriate patient management.
