Multiple Nodular Metastases to Lung, Colon Cancer. There are multiple masses in both lungs of varying size
implying multiple episodes of tumor embolization. Such nodules are usually hematogenously spread from their primary, in this case colon carcinoma.
Cavitary Metastases to the Lung. Frontal chest radiograph shows multiple masses
in both lungs. Several of the masses are cavitary (white arrows). The patient had squamous cell carcinoma of the esophagus
Metastases to the Lung, breast carcinoma. Frontal chest radiograph shows multiple masses
in both lungs. There are multiple surgical clips in the left axilla (black arrows) from a radical lymph node dissection. The patient had a primary breast cancer in the left breast.
