Duodenal Diverticulum: Symptoms & Signs

Medically Reviewed on 9/24/2021

A duodenal diverticulum is a pouch attached to the duodenum, the second part of the small intestine just past the stomach.

A duodenal diverticulum is usually asymptomatic, meaning that it does not produce signs or symptoms. Occasionally, a duodenal diverticulum may rupture, leading to an area of inflammation adjacent to the duodenum with or without infection. If this occurs, signs and symptoms of intra-abdominal inflammation can occur, including fever, pain, and abdominal tenderness.

Cause of a Duodenal Diverticulum

The exact cause of duodenal diverticulum is not understood, but they are believed to be acquired (not present from birth) due to a herniation (protrusion) of the duodenum through a defect in the duodenal muscle wall.
