CTICasesSolitary Renal Cell Carcinoma Metastasis to the Anterior Mediastinum
Imaging findings
CT shows an isolated, hypervascular, enhancing anterior mediastinal nodule with surrounding reactive lymphadenopathy in a patient who previously underwent nephrectomy for renal cell carcinoma. Biopsy and resection confirmed a solitary metastasis.
Key takeaways
Renal cell carcinoma is notorious for late, atypical metastatic presentations. A solitary hypervascular metastasis to the anterior mediastinum can mimic a primary thymoma or thyroid mass, requiring careful correlation with history and biopsy.
