Imaging findings
CTA demonstrates a discrete, enhancing filling defect within the innominate vein, extending into the superior vena cava. PET scan confirms metabolic activity confined to the venous system.
Key takeaways
Intravascular metastasis, especially as the sole site of recurrence from a remote prostate cancer, is a rare and unusual manifestation. Cancer can present in unexpected ways, and a history of malignancy should prompt consideration for unusual metastatic patterns.
