Isolated Adrenal Mass in Patients with a History of Cancer: Remember Pheochromocytoma

Background In a patient with a history of cancer, an isolated adrenal mass is usually thought to be a metastasis. Although a biochemical work-up to rule out pheochromocytoma is recommended, some question its practicality. This study was undertaken to determine the incidence of functional adrenal lesions in patients with a history of cancer and examine predictive factors for the type of lesion.
