CTICasesExtensive Tumor Emboli from Sarcoma Recurrence

Imaging findings
Initial radiographs showed a history of arthroplasty in the right shoulder due to metastatic sarcoma. Later images revealed extensive abnormality in the right first costoclavicular space, suspicious for tumor involving adjacent vessels. CT showed tremendous tumor growth into the brachiocephalic vein, extending down into the right atrium and right ventricle, with large tumor emboli growing into the pulmonary arteries bilaterally, particularly on the right side.
Key takeaways
Sarcomas can metastasize and recur aggressively, with the potential for direct invasion into large vessels and subsequent extensive tumor embolization into the heart chambers and pulmonary arterial tree. This represents a severe form of tumor progression with significant clinical implications.
