Cavernous hepatic hemangioma at 18F-choline positron emission tomography-computed tomography: Be aware of the pitfall

We report a case of a patient performing a positron emission tomography-computed tomography (PET-CT) scan with [18F]F-Choline for biochemical relapse (Prostate specific antigen (PSA) 1.2 ng/ml) of prostate cancer. Two large areas of focal uptake with a cold core within the liver were observed. A contrast-enhanced ultrasound scan performed after the PET scan characterized these lesions as cavernous hepatic hemangiomas, and therefore, a biopsy was not performed; 3 years of follow-up and PET and MRI finding stability confirmed the benignity of their nature.
