From: Low-grade extraskeletal osteosarcoma of the chest wall: case report and review of literature
Radiological features 4.5 years after the first symptoms. (A) CT scan: thoracic transversal view showing a voluminous heterogeneous highly calcified mass. It included the whole left chest wall and the left scapula, with intercostal invasion to the apical pleura (black arrows) and the antero-superior mediastinum (bolt) with trachea deflection to the right. (B) Bone scan with Technecium 99: see the heterogeneous extended hyperfixation of the whole left side of the chest. There was a muscular extension to the triceps leading to a frozen scapulo-humeral joint.
