Bare area of the liver

Bare Area of the Liver

The Bare Area of the Liver is a region on the posterior surface of the liver that is not covered by the peritoneum, a continuous layer of tissue that usually covers the abdominal organs. This area is named 'bare' because it is directly in contact with the diaphragm, without any intervening peritoneum.

Anatomy

The bare area is located between the right and left triangular ligaments, which are part of the coronary ligament of the liver. The coronary ligament is a double layer of peritoneum that attaches the liver to the diaphragm and the anterior abdominal wall. The bare area is the largest area of the liver's posterior surface and is shaped like a triangle.

Clinical Significance

The bare area of the liver has clinical significance in the spread of infections from the abdominal cavity to the thoracic cavity. Because it is not covered by the peritoneum, infections can spread directly from the liver to the diaphragm and into the pleural cavity, potentially leading to pleurisy or pleural effusion.
