INTRODUCTION: Intestinal duplication is rarely reported in adulthood and often remains undiagnosed until onset of complications. We describe the case of a 39 year old @entity1 who came to our observation for acute abdomen due to a combination of double intestinal duplication (colon and ileum) and an incidental @entity5 . MATERIALS AND METHODS: A 39 year old @entity1 who was admitted at with upper @entity490 . Multisliced spiral CT scan showed a cystic lesion suggestive of an inflammed Meckel's diverticulum.The @entity1 was underwent an urgent explorative laparoscopy. The intraoperative findings revealed a cystic lesion of the anti-mesenteric side of transverse colon, apparently dissectable from the bowel and a second lesion with a strongly adherent and unresectable from the anti-mesenteric aspect of the small bowel. A combined appendectomy was also performed. The histological diagnosis was consistent with a typical intestinal duplication for both intestinal lesionsand an incidental 2mm @entity5 was also found in the appendix. The postoperative course was uneventful and the @entity1 was discharged on p.o. day 5. At the presenttime she is well and following a regular oncologic follow-up. DISCUSSION: The rarity of this case is due to the concomitant presence of an incidental, sincronous, appendiceal NET. The elective treatment is surgical resection. CONCLUSION: Intestinal duplication in the adulthood is extremely rare and may either have an acute presentation as acute abdomen or represents an incidental finding of mass. We suggest that, once the diagnosis is suspected @entity1 must undergo surgery.
