Calcified liver metastases are reasonably uncommon and usually associated with metastatic mucinous adenocarcinoma (gastric or colonic in origin).  Prostatic metastases are typically sclerotic in bone, but very rarely calcified in soft tissues although it has been reported (see below).  Given the positivity on nuclear bone scan, these lesions are not just calcified but actively ossifying. The effect is a primary phenomenon and not post-chemotherapy as the patient has not yet received any such treatment.
