They are surrounded by loosely attached fat posteriorly to diaphragmatic muscle. This fat can obscure the visualization and identification of adrenal tumors. Left-sided adrenal tumors lie adjacent to and can invade the spleen, pancreas tail, liver, kidney, or renal hilum. If not careful, it is possible to mistake the tail of the pancreas for the left adrenal gland given the similar texture and size. Right-sided adrenal tumors lie adjacent to and can invade the liver or inferior vena cava (IVC).
