title: FDG PET/CT Imaging of Prostate Carcinosarcoma.
abstract: We present a case of carcinosarcoma of the prostate. Workup of urinary retention after a previously treated squamous cell carcinoma of the prostate led to a transurethral prostate resection revealing carcinosarcoma of the prostate, which on F-FDG PET/CT demonstrated moderate to high avidity of this atypical prostate cancer, with partial obstruction of the urinary system and lung metastases. While FDG PET is not avid for typical prostatic adenocarcinomas, it should be considered for evaluation of atypical prostate cancers.
