Findings: Multiple variable-sized lytic lesions are seen in the whole visualized bony skeleton. A soft tissue component is seen along with a few rib lesions, with the largest component seen along the right 4th rib. Multiple mildly enlarged mediastinal lymph nodes are seen. Enlarged thyroid gland with retrosternal extension and a few small nodules in both lobes. No pleural/pericardial effusion, pneumothorax/pneumomediastinum, or suspicious pulmonary nodule/mass is seen.
Conclusion: Multiple lytic lesions involving the visualized bony skeleton. Prime diagnostic consideration is multiple myeloma; another possibility can be bone metastases.
