CT
What differential diagnoses would you consider?
Differential in this age group includes, prostatic sarcoma, primary malignant melanoma of the prostate, atypical prostate cancer, as well as tumours of the bladder seminal vesicles (less likely).
CT scan demonstrates a large heterogenous mass seemingly arising from the prostate with evidence of invasion into the bladder, seminal vesicles and periprostatic soft tissues.
Numerous hepatic and pulmonary metastases are present.
