Metastatic prostatic pulmonary nodules with normal bone image.

Asymptomatic prostatic carcinoma presented as multiple bilateral pulmonary nodules in a patient without any evidence of skeletal involvement by normal bone image. Percutaneous biopsy provided the initial clue to diagnosis. We recommend that asymptomatic prostatic carcinoma be included in the differential diagnosis of pulmonary nodules, even when there is no evidence of skeletal metastasis.
