Introduction Intussusception is telescoping or invagination of one part of the intestine (intussusception) into an adjacent section (intussuscipiens) and it may present as a life threatening condition. Intussusception is so rare in adults and small intestine intussusception in adults is usually due to benign entity; whereas in large intestine, malignant neoplasms can be the etiology. Here, we reported a rare case of adult jejunojejunal intussusception due to a jejunal villous adenoma polyp in an Iranian female patient. Case Presentation A 33-year female Iranian patient referred to emergency department in Gastroenterology and liver diseases Research Center, Shahid Beheshti University of Medical Sciences with extreme abdominal pain, nausea and constipation. Plain abdominal computed tomography (CT) scan revealed a mass suggesting intussusception in the jejunum. Balloon association enteroscopy showed two 10 mm and 40 mm polyps in jejunum. The polyp was a villous adenoma confirmed by pathology. Exploratory laparotomy revealed jejunojejunal intussusceptions and exploratory laparotomy with jejunoileal anastomosis was performed. Conclusions Nonspecific symptoms of an adult intussusception might result in a late diagnosis and imaging modalities including CT scan play a significant role in the diagnosis. Surgical operation is the best treatment in adult intussusception leading to the best results.
