Coronary ligament
Ligamentum coronarium
Definition
The coronary ligament of the liver is composed of two layers a superior (anterior) layer and an inferior (posterior) layer both of which are peritoneal reflections connecting the liver to the diaphragm and adjacent retroperitoneal structures. Because the liver is posteriorly connected to the diaphragm, these layers are more accurately described as superior and inferior rather than anterior and posterior, though both terminologies are used in clinical practice.
The anterior part of coronary ligament (superior layer) reflects from the diaphragm onto the superior surface of the right lobe of the liver.
The posterior part of coronary ligament (inferior layer) reflects from the inferior surface of the right lobe of the liver onto the right kidney and adrenal gland, forming the hepatorenal ligament. This layer constitutes the upper boundary of the hepatorenal recess (Morison's pouch).
