Ga-prostate-specific membrane antigen (Ga-PSMA) PET/CT has shown excellent results in imaging of prostate cancer. Some nonprostatic malignancies can also demonstrate Ga-PSMA uptake, including primary lung adenocarcinoma. However, no such data are present for small cell lung cancer. We present the case of a 59-year-old man, where a second primary metastatic small cell lung cancer was discovered on Ga-PSMA PET/CT done for suspected recurrence of prostate cancer.
