Rib Fractures Mimicking Bone Metastases in 18F-PSMA-1007 PET/CT for Prostate Cancer

Clin Nucl Med. 2019 Jan;44(1):e46-e48. doi: 10.1097/RLU.0000000000002354.

Abstract

Prostate-specific membrane antigen (PSMA) is a membrane glycoprotein that is overexpressed in prostate cancer cells. It is also expressed in other normal tissues and several other malignant and benign diseases. We present a case of a 69-year-old man with history of prostate adenocarcinoma who underwent F-PSMA-1007 PET/CT due to suspected biochemical recurrence. PET/CT showed F-PSMA-1007 uptake in healing rib fractures with no other pathologic findings. Clinicians reporting F-PSMA-1007 PET/CT should be aware of this potential pitfall, especially in nontypical trauma pattern (eg, solitary osseous lesion) mimicking bone metastases.
