| right triangular ligament | <anatomy> A triangular fold of peritoneum that passes from the right lobe of the liver to the diaphragm; it is a formation of the coronary ligament, formed as the coronary ligament makes an acute angle upon reaching its most lateral point on the right side as it surrounds the bare area of the liver.

Risk factors include diabetes, alcoholism, obesity and smoking.
