[Duodenal duplication cyst filled with enteroliths: a case report]

Abstract

Alimentary tract duplications are very rare, especially among adults, and only in 4-12% of the cases the duodenum is the site of origin. The main symptoms are usually epigastric pain, weight loss and vomiting. We report a case of a duodenal duplication cyst filled with enteroliths in a 23-year-old female patient presenting these symptons. The computed tomography showed a mesenteric cyst and the patient underwent a surgical procedure during which the diagnosis of duplication cyst with enteroliths was made and the cyst was excised with success. The diagnosis before surgery in these cases is extremely difficult especially if one considers how rare they are. The most helpful exam is the computed to- mography and the treatment is mainly surgical, although there are recent case reports showing the possibility of endoscopic resection (still being discussed). The presence of enteroliths can be explained by stasis and food alkalinity inside the cyst.
