Drug treatment: benign adrenal cysts with a diameter less than or equal to three centimeters and without any symptoms can be temporarily left untreated with regular checkups. If there are complications, such as inflammation, anti-infection treatment can be carried out, can take metronidazole under the guidance of the doctor. 2.
