CTICasesHypervascular Lymph Node Metastasis
Imaging findings
CT chest shows a highly vascular, intensely enhancing right lower paratracheal lymph node mass (metastasis from renal cell carcinoma) demonstrating a prominent, dilated, tortuous draining vein.
Key takeaways
Hypervascular metastases (such as from renal cell carcinoma, thyroid cancer, or melanoma) to lymph nodes can alter regional perfusion, causing significant enlargement of associated draining veins. This vascular recruitment should not be mistaken for a vascular anomaly or primary aneurysm.
