The adrenal glands are paired retroperitoneal endocrine organs. They are thin, inverted Y- or V-shaped soft tissue structures and have flat or concave margins. The vertical length of each gland may be anywhere from 2 to 4 cm. Their “limbs” are approximately 0.4 cm thick in axial cross-section, which is roughly as thin as the adjacent diaphragmatic crus.
