Serendipitous Detection of Hepatocellular Carcinoma in a Patient Undergoing Staging for Prostate Cancer

Isolated liver metastasis from prostate cancer is exceedingly rare. Prostate-specific membrane antigen-positron emission tomography/computed tomography has become the one-stop shop imaging in prostate cancer, but the uptake is a relatively nonspecific tracer and its expression can be seen in a plethora of nonprostatic solid tumors. We report one such example of an oligometastatic prostate cancer who presented with an isolated liver lesion which turned out to be an incidental hepatocellular carcinoma, thus representing a potentially unique diagnostic challenge.
