Perforated Non-Meckel Ileal Diverticulum Mimicking Neoplastic Lesion: A Case Report

Non-Meckel small bowel diverticulosis is a rare condition often asymptomatic but capable of causing complications such as hemorrhage, perforation, and obstruction.It primarily affects elderly men, with the duodenum being the most common site.The pathogenesis is linked to myenteric plexus dysfunction, leading to increased intraluminal pressure and wall herniation.This case study presents a 58-year-old male admitted with acute abdominal symptoms.Imaging revealed free peritoneal fluid and intraperitoneal gas, prompting emergency laparotomy.Early diagnosis and appropriate treatment are crucial for preventing severe outcomes.Histopathological examination is necessary to rule out malignancy, particularly in emergency cases.Small bowel diverticulosis should be considered in differential diagnoses of acute abdomen.
