The adrenal gland is a common site of metastases, only second to pulmonary, liver and bone. The prevalence of adrenal metastases in patients with a history of cancer is between 10%-25%.The most common sites of origin are cancers of the lung, kidney, breast, gastrointestinal tract, and skin (melanoma).The mainstays of adrenal metastases diagnosis are computerized tomogramphy (CT), magnetic resonance imaging (MRI), and positron emission tomogramphy (PET). All patients should undergo complete hormonal evaluation to rule out functional adrenal tumors. Adrenal biopsy should be reserved for cases in which the results of non-invasive techniques are equivocal. In patients with isolated adrenal metastases, adrenalectomy is recommended, because of improved overall survival. For the patient with unresectable adrenal metastases tumor, radiotherapy and ablative therapy are feasible and useful methods for controlling adrenal metastases and offer patients opportunities for improved survival.
