Aim: Duodenal diverticulum is the second most common diverticulum section in the gastrointestinal system, but perforation is rare. It is frequently diagnosed incidentally and has little clinical evidence. There are no certain treatment strategies for duodenal diverticulum perforation. Our aim is to identify perforated duodenal diverticulum cases published in the last 10 years through our case report and to evaluate different approaches to treatment. Case Report: A 58-year-old male was diagnosed central nervous system (CNS) tumor with a perforated duodenal diverticulum. Our case presented with abdominal pain and pneumoperitoneum on imaging. The patient was treated surgically with an omental patch, pyloric exclusion, retrocolic gastrojejunostomy, and tube duodenostomy. The patient died on the 10th postoperative day. Conclusion: Duodenal diverticulum perforation is a rare but fatal condition. CT is useful in diagnosis. If the patient is not in a septic condition, it can be followed conservatively. However, if the patient is in a septic condition, surgery may be required. Surgical options should be determined based on the perforation site and characteristics.
