Structure
The bare area of the liver is found on the posterosuperior surface of the right lobe of the liver. This lies close to the thoracic diaphragm. It is the only part of the liver that has no peritoneal covering. It lies between the two layers of the coronary ligament, as well as the right triangular ligament. The coronary ligament represents reflections of the visceral peritoneum covering the liver onto the diaphragm.
The bare area of the liver is attached to the thoracic diaphragm by loose connective tissue. It touches the bottom surface of the diaphragm. It is also not covered in capsule.

Clinical significance
The bare area of the liver is clinically important because of the portacaval anastomosis. It is a site where infection can spread from the abdominal cavity to the thoracic cavity. Traumatic injury involving the bare area of the liver can result in retroperitoneal hemorrhage as this region is not covered by visceral peritoneum. It encloses the right extraperitoneal subphrenic space.
History
The bare area of the liver may also be known as the nonperitoneal area.
