RESUMO
ABSTRACT: A 51-year-old man with newly diagnosed small cell neuroendocrine carcinoma of the prostate was referred for a staging 18 F-DCFPyL PET/CT, which showed a solitary metastasis in the left acetabulum. Subsequent 18 F-FDG PET/CT showed intense uptake throughout the prostate as well as extensive avid pelvic and thoracic nodal disease and redemonstration of the left acetabular metastasis. Despite initial metabolic response to treatment, subsequent 18 F-FDG PET 8 months later revealed significant progression of nodal disease above and below the diaphragm, as well as multiple new sites of metastases.

ABSTRACT: An 83-year-old man was referred for an 18 F-DCFPyL PET scan for the evaluation of rising serum prostate-specific antigen level on the background of previous radical prostatectomy for prostate adenocarcinoma and urinary outflow tract obstruction requiring in-dwelling catheter insertion. The PET scan demonstrated focal increased activity (SUV max , 35.7) at the dorsal aspect of the mid penile shaft, with histopathological confirmation of penile metastasis from primary prostate cancer.

ABSTRACT: A 64-year-old man with recently diagnosed prostate adenocarcinoma and Gleason score 4 + 3 = 7 with a mildly elevated prostate-specific antigen of 5.17 µg/L was referred for 18 F-DCFPyL PET/CT for primary staging. The scan demonstrated incidental innumerable moderately avid subcutaneous nodules due to adiposis dolorosa (Dercum's disease), which is a rare adipose tissue disease.
