A case of renal cell carcinoma with synchronous contralateral adrenal metastasis

A 73-year-old female visited our department with right incidentally-found renal tumor, which was revealed by follow-up computed tomography (CT) on an annual physical check-up. CT also showed a left adrenal mass that was 4 cm. Further evaluation suggested right renal cell carcinoma and left adrenal metastasis. The patient, therefore, underwent right-adrenal-gland-sparing radical nephrectomy and left adrenalectomy. The pathology report indicated renal cell carcinoma with contralateral adrenal metastasis. A case of contralateral adrenal metastasis from renal cell carcinoma is not common clinically. Furthermore, whether ipsilateral adrenalectomy should be performed in such a case is still controversial at this stage.
