CTICasesHypervascular Chest Wall Renal Cell Metastasis
Imaging findings
Surveillance CT shows a small, highly vascular soft tissue nodule along the trapezius muscle, arising 7-8 years after a nephrectomy for renal cell carcinoma. Angiography shows the tumor parasitizing flow from chest wall and paraspinal arteries.
Key takeaways
Renal cell carcinoma metastases can appear decades after the primary resection. They are characteristically hypervascular and can present as painful chest wall/soft tissue metastases parasitizing regional arteries.
