Cannonball Lesions: A Case Report.

Cannonball lesions refer to multiple, well-defined, round pulmonary metastases seen on chest radiographs or CT scans. They are most commonly associated with hematogenous spread of malignancies, most frequently linked to renal cell carcinoma, choriocarcinoma, colorectal cancer, and breast cancer. We report a case of cannonball pulmonary metastases secondary to hepatocellular carcinoma (HCC).
