Fig. 23.18 Cushing's syndrome: right adrenal adenoma demonstrated by CT. Adrenal adenomas causing Cushing's syndrome are usually 2ΓÇô5cm in size. They are readily detected by CT because of the contrast provided by the abundant retroperitoneal fat which is present in most patients. This scan shows a 3.5cm rounded mass in the right adrenal gland. It lies immediately behind the IVC and between the liver and the right crus of the diaphragm.
