Cannonball metastases refer to multiple large, well-circumscribed, round pulmonary metastases. Numerous primary tumors have been described presenting with cannonball metastases, however, some primary tumors have a predilection for this presentation.
It should be noted that it is difficult to find a definitive list of common primaries presenting in this manner; therefore, sources differ substantially in the list they provide 1-3.
