Prostate-specific membrane antigen (PSMA)-PET/CT as an emerging modality in molecular imaging will lead to earlier detection and localization of relapse in prostate cancer but will undoubtedly also lead to false-positive findings, as it becomes clear that this new tracer is not as specific as its name would suggest. In this context, we present a case of a large PSMA-expressing schwannoma, a rare nerve sheath tumor mimicking paraesophageal lymph node metastasis in a patient with a history of prostate cancer and biochemical recurrence.
