Pancreatic divisum is the most common anomaly of the pancreas. Pancreatic divisum associated with malignant tumor is rarely seen. The ampulla of Vater is formed by the union of the common bile duct and the pancreatic duct. The incidence of malignant tumor in the ampulla of Vater is very low. Adenomas and carcinomas are more common. Neuroendocrine tumors originate from enterochromaffin cells of the neuroendocrine system. Ampullary neuroendocrine tumors are very rare and preoperative diagnosis is very difficult. In the literature, the emphasis on imaging characteristics of similar cases is limited. Herein, we present a rare case of pancreatic divisum associated with ampullary neuroendocrine tumor and its characteristics of computed tomography and magnetic resonance imaging.

Midgut volvulus mezenter kökünün süperior mezenterik arter etrafında rotasyonuyla oluşan nadir görülen bir malrotasyondur.Çoğunlukla İnfantlarda görülmesine rağmen erişkinlerde de görülebilmektedir.Çok kesitli bilgisayarlı tomografi başta olmak üzere, ultrasonografi, ince barsak grafisi tanıda önemli katkılar sağlamaktadır. Biz semptomatik olarak tedavi edilen midgut volvuluslu erişkin olguyu sunduk ve literatürü tartıştık.

Aim:To investigate the role of non-contrast magnetic resonance imaging (MRI) and findings of quantitative MRI in the evaluation of pancreatic lipomatosis in patients undergoing bariatric surgery.Methods:Pre-operative and post-operative MRI findings and laboratory test results of 44 obese patients, who underwent sleeve gastrectomy, were reviewed retrospectively. Liver craniocaudal length, hepatic and pancreatic region of interest (ROI) ratios at in-phase and out-of phase sequences (in-phase/out-of phase), pancreas/spleen ROI ratio on T2-weighted sequence (T2 ratio) and thickness of subcutaneous fat were estimated. The relationship between pre-operative and postoperative findings was analyzed.Results:A total of 44 (41 female, three male) patients with a mean age of 42 were included in the study. Liver length, hepatic and pancreatic in-phase/out-of phase ratios, pancreas/spleen T2 ratio and thickness of subcutaneous fat in the post-operative period were found to be lower than those in the pre-operative period (p

Small intestine tumors are extremely rare. They account for approximately 1-5% of all gastrointestinal tumors. However, the risk of development of small intestine tumor increases in patients with celiac disease. Celiac disease is also known as gluten-sensitive enteropathy. Lymphoma is the most common small intestine tumor in patients with Celiac disease. Adenocarcinoma and adenoma of the small intestine are less common. Adenocarcinoma is frequently seen in the proximal segments of the small intestine. The prognosis of adenocarcinoma is worse than lymphoma. In the literature, there are few reported cases of duodenal adenocarcinoma in patients with Celiac disease and the imaging findings were not emphasized enough. For this reason, in this study, computed tomography and magnetic resonance imaging findings in a patient with duodenal adenocarcinoma associated with Celiac disease are presented.
