We describe the case of a 39 year old woman who came to our observation for acute abdomen due to a combination of double intestinal duplication (colon and ileum) and an incidental neuroendocrine tumor of the appendix.<\/jats:p>\n <\/jats:sec>\n \n MATERIALS AND METHODS:<\/jats:title>\n A 39 year old woman who was admitted at with upper abdominal pain.<\/jats:p>\n Multisliced spiral CT scan showed a cystic lesion suggestive of an inflammed Meckel\u2019s diverticulum.The patient was underwent an urgent explorative laparoscopy.<\/jats:p>\n 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.<\/jats:p>\n The histological diagnosis was consistent with a typical intestinal duplication for both intestinal lesionsand an incidental 2 mm carcinoid tumor was also found in the appendix.<\/jats:p>\n The postoperative course was uneventful and the patient was discharged on p.o. day 5. At the presenttime she is well and following a regular oncologic follow-up.<\/jats:p>\n <\/jats:sec>\n \n DISCUSSION:<\/jats:title>\n The rarity of this case is due to the concomitant presence of an incidental, sincronous, appendiceal NET.<\/jats:p>\n The elective treatment is surgical resection.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSION:<\/jats:title>\n 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.<\/jats:p>\n We suggest that, once the diagnosis is suspected patient must undergo surgery.<\/jats:p>\n <\/jats:sec>\n \n Highlights<\/jats:title>\n <\/jats:sec>","DOI":"10.1016\/j.ijscr.2015.06.021","type":"journal-article","created":{"date-parts":[[2015,7,6]],"date-time":"2015-07-06T20:37:33Z","timestamp":1436215053000},"page":"116-118","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Double intestinal duplication and incidental neuroendocrine tumor of appendix, a rare case of acute abdomen"],"prefix":"10.1097","volume":"13","author":[{"given":"G.","family":"Bellanova","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Valduga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Costa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Barbareschi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"De Carli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Giannelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Di Sipio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Prezzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.A.","family":"Ciarleglio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Beltempo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Marcucci","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Giacomin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Depretis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Brolese","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-32-20260114","doi-asserted-by":"crossref","first-page":"415","DOI":"10.1016\/S0344-0338(11)80728-4","article-title":"Duplication in a non rotational colon study of a case associated with mucinous adenoma","volume":"191","author":"Diaz-Cano","year":"1995","journal-title":"Pathol.
