Abstract

<p>A 59-year-old woman was referred to our hospital because of lower abdominal pain. Contrast-enhanced computed tomography (CT) revealed a cystic mass with an 8-cm diameter and two solid masses with a 3-cm and 2-cm diameter in the lower abdomen. The solid masses exhibited contrast enhancement. A gastrointestinal series showed an enhanced cystic lesion in the pelvic cavity and it was suggested that the lesion communicated with the small intestine. We performed surgery under the suspected diagnosis of penetration of the gastrointestinal stromal tumor (GIST) into the intestinal lumen. Upon laparotomy, a 15-cm duplication of the alimentary tract was found on the opposite side of the mesentery, located 150 cm distal to the ligament of Treitz. Hard elastic nodules adjacent to the spherical duplication were palpable. The duplication of the alimentary tract and nodules were resected. On histopathologic examination, the nodules were diagnosed as ectopic pancreatic tissue.</p><p>Jejunal duplication associated with ectopic pancreatic tissue is very rare ; therefore, we present this case with a review of the literature.</p>
