A 66 year old man that was diagnosed with prostate cancer underwent radical prostatectomy 2 years ago. Pathology result of the surgical specimen revealed poorly differentiated prostate carcinoma with positive surgical margins. He was treated with antiandrogens and adjuvant radiation therapy. Since the beginning of the last year and under hormonal monotherapy with Casodex his PSA levels doubled. PET CT of the abdomen and the pelvis revealed hepatic lesion.
