Annular pancreas associated with nutcracker syndrome: A case report

Abstract

The pancreas usually develops from the fusion of the dorsal and ventral pancreatic buds between the first 4-8 weeks of embryonic life. Annular pancreas consists of a ring of pancreatic tissue, which partially or completely surrounds the descending portion of the duodenum. Annular pancreas is an uncommon congenital anomaly. The etiology of this anomaly is still unknown. It has been associated with other congenital anomalies and various clinical symptoms. The nutcracker phenomenon is defined as compression of the left renal vein between the aorta and superior mesenteric artery. We report the case of a 54-year-old patient who presented with a 15-day history of nausea and vomiting associated with weight loss. On magnetic resonance cholangiopancreatography (MRCP) and computer tomography (CT) examination, an annular pancreas and nutcracker syndrome were diagnosed, respectively. In this study, we founded that the radiologic and clinical findings of associated annular pancreas with nutcracker syndrome may be of clinical importance for surgical procedures.

Nutcracker sendromu ile birlikte anüler pancreas: Olgu sunumu

Abstract

Pancreas genellikle embriyolojik hayatın ilk 4-8 haftaları arasında dorsal ve ventral pankreas tomurcuklarının birleşmesinden gelişir. Anüler pancreas, pancreas dokusunun pars descendens duodeni\'yi kısmi ya da tamamen halka şeklinde sarmasıyla oluşur. Anüler pancreas yaygın olmayan bir konjenital anomalidir. Bu anomalinin etyolojisi hala bilinmemektedir. Bu anomali, diğer konjenital anomaliler ve çeşitli klinik semptomlarla birliktelik gösterebilmektedir. Nutcracker fenomeni, v.renalis sinistra\'nın aorta abdominalis ile a.mesenterica superior arasında sıkışması olarak tanımlanır. 15 gündür bulantı ve kusma ile birlikte kilo kaybı olan 54 yaşında bir hastanın olgusunu bildirdik. MRKP (Manyetik rezonans kolanjiopankreatografi) ve BT (bilgisayarlı tomografi) incelemelerinde anüler pancreas ve nutcracker sendromu tanısı konuldu. Biz bu çalışmada, radyolojik ve klinik olarak anüler pankreas ile nutcracker sendromunun birlikteliğininin cerrahi girişimler için klinik açıdan önemli olabileceğini gösterdik.
