Diagnosis With Brief Discussion

Diagnosis
Chondrosarcoma
Radiologic Findings
Fig 1. Chest radiograph shows nodular opacity with calcifications in right 4th rib anterior arc.
Fig 2-8. CT scan reveals small soft tissue lesion with bony destruction, containing internal stippled chondroid calcifications in right 4th rib.
Brief Review
Chondrosarcoma, the most common primary malignant rib neoplasm, usually arises at or near the costochondral junction. Its incidence tends to peak at the age of 50 years; it is rare in individuals younger than 20 years. Although some chondrosarcomas may not have radiographically visible calcifications, most feature lobulated masses containing the typical flocculent, stippled, or ring- and arclike calcifications and usually involve the anterior rib at the costochondral junction and show osseous expansile remodeling with a ring-and-arc pattern of calcification and soft-tissue extension on both radiographs and CT.
