Diagnosis With Brief Discussion

Diagnosis
Chondrosarcoma
Radiologic Findings
CT scan shows an about 7cm sized lobulated enhancing mass in left 9th rib near the costochondral junction, with bony destruction, containing internal stippled chondroid calcifications and necrotic portion. Invasion was suspicious, into L diaphragm and adjacent chest wall muscles.
Brief Review
Chondrosarcoma is the most common primary malignant rib neoplasm, usually arises at or near the costochondral junction. Incidence 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 lesions 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. The nonmineralized components, both intraosseous and extraosseous, typically have low attenuation on CT scans, reflecting the high water content of hyaline cartilage. CT performed after intravenous administration of contrast material demonstrates mild peripheral rim and septal enhancement. Higher-grade lesions may show higher CT attenuation, similar to that of muscle, and more prominent diffuse or nodular contrast enhancement, caused by increased cellularity and resultant reduced water content.
