> In conclusion, the solitary contralateral adrenal metastasis from RCC is an extremely rare clinical complication that can occur very late after the radical nephrectomy. The increased

use of radiological diagnostic tests like: ultrasound, CT and/or MRI has led to more efficient detection of these lesions. Aggressive surgery remains the treatment of choice in these cases improving prognosis in some of the patients. There is no doubt that the existing data are limited and we need more studies to define the optimal management strategy in the patients with contralateral adrenal metastasis from RCC.
