Cannonball metastases

A 44 year old male, k/c/o Right Renal cell carcinoma p/w severe shortness of breath. CXR - multiple large, well-circumscribed, round homogenous opacities, that appear not unsurprisingly like cannonballs.  The French terms "envolée de ballons" and "lâcher de ballons",  which translate to "balloons release", are also used to describe this same appearance. Commonly seen in RCC and Choriocarcinoma but can also be seen with certain other malignancies (prostate, adrenal, endometrial etc).
