Renal cell carcinoma often metastasizes to the adrenals; however, bilateral adrenal metastases are rare. We here report a patient with bilateral adrenal metastases from renal cell carcinoma after robot-assisted partial nephrectomy and review relevant published reports. A 64-year-old man underwent robot-assisted partial nephrectomy for a left renal tumor. During follow-up, he was diagnosed with bilateral adrenal metastases. He underwent left adrenalectomy followed by right partial adrenalectomy to preserve adrenal function. The renal tumor later metastasized to other parts of the body. He continues to receive systemic treatment and remains in partial remission. Patients with pT1aN0M0 renal cell carcinoma generally have a favorable prognosis. However, occasional such patients develop multiple metastases. To the best of our knowledge, this is the first reported case of bilateral adrenal metastases after partial nephrectomy. Clinicians should keep this rare scenario in mind.
