👉 A diverticulum is a formation of connective tissue that protrudes from the wall of the large intestine. These diverticula are often found in the right lower quadrant, especially near the umbilicus. They are characterized by their irregular shape and size, which can vary widely in size and location. The cause of these diverticula is not fully understood, but they may be related to an underlying inflammatory process, such as Crohn's disease or ulcerative colitis.
