Isolated metachronous contralateral adrenal metastasis from renal cell carcinoma.

Isolated contralateral adrenal metastasis from renal carcinoma is extremely rare. Patients who present with this entity often undergo surgery with the presumed diagnosis of an incidentaloma. A mass in the contralateral adrenal diagnosed following radical nephrectomy for renal carcinoma should be viewed with a high index of suspicion for the presence of metastatic disease. Surgery is the only effective management option and should be offered to these patients.
