Incidentally Detected Gastrointestinal Stromal Tumor in a Patient with Carcinoma Prostate: (68)Ga-Prostate-Specific Membrane Antigen Versus (18)F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

Uptake of (68)Ga-prostate-specific membrane antigen (PSMA) in various nonprostatic tumors is well documented in the literature. We present a case of a gastrointestinal stromal tumor, incidentally detected on (68)Ga-PSMA positron emission tomography/computed tomography imaging in a patient who underwent imaging for a suspected recurrence of carcinoma prostate.
