[Incidental finding: left sided cystic adrenal mass]

Because of the widespread use of imaging techniques the incidental diagnosis of an adrenal mass without clinical symptoms and pathologic laboratory values becomes more and more common. To avoid unnecessary therapeutic interventions an intensive evaluation should take place including blood and urine testing as well as radiologic examination. An accurate assessment is often helpful in making the diagnosis of a benign process to avoid an invasive procedure and to determine the frequency and intensity of further controls. Nevertheless, in some cases the invasive approach is necessary because of an unclear situation or because of influences caused by the patient. An advantage is the possibility of laparoscopic intervention because of the minimal morbidity and until now no reported mortality.
