Paraduodenal hernia is a rare condition; however, it is the most common cause of internal hernia (2).
Paraduodenal hernia carries an approximately 50% lifetime risk of incarceration, leading to bowel obstruction and strangulation; therefore, it should be repaired surgically when diagnosed (4, 8).
Paraduodenal hernia is very rare, and preoperative diagnosis is difficult because there are no specific symptoms or physical examination findings.
