Beyond the Usual Suspects: Abdominal Wall Metastases in Prostate Cancer Diagnosed by 68Ga-PMSA PET/CT

Abstract

⁶⁸Ga-PMSA PET imaging has revolutionized both diagnosis and radioligand therapy selection in patients with
metastatic prostate cancer. We report the case of a 63-year-old man with prostate adenocarcinoma who underwent
radical prostatectomy followed by radiation therapy and ADT. Found to have rising PSA levels and referred for 68Ga-
PSMA PET/CT for restaging. ⁶⁸Ga-PSMA PET/CT showed multiple suspicious ⁶8Ga-PSMA PSMA avid mediastinal
lymph nodes and an avid lesion in the right lower anterior abdominal wall; suspicious for metastasis.
Ultrasonography guided biopsy showed metastatic prostate adenocarcinoma. In our cases, ⁶⁸Ga-PSMA PET/CT
identified the unexpected metastatic site which leads to change patient management and potentially improving
patient outcome.
Keywords: ⁶⁸Ga-PSMA PET/CT; prostate cancer; anterior abdominal wall metastasis.
