Developmental anomalies and anatomic variants of the pancreas vary widely, and most of them are encountered incidentally during radiologic evaluation. However, some of these anomalies and variants are potentially pathologic and may cause various clinical presentations in childhood or adulthood. The early identification of these entities in various imaging modalities including ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging would be valuable in making correct diagnoses and, in turn, preventing unnecessary additional procedures. In order to differentiate these entities, it is fundamental to understand the embryologic development and normal anatomical structure of the pancreas. In this article, we review the embryology and normal anatomy of the pancreas, and diagnostic pitfalls of developmental anomalies and anatomic variants in various pancreatic imaging modalities.
胰腺的发育异常和解剖变异差异很大，其中大多数是在影像学评估时偶然发现的。然而，这些异常和变异中的一些可能具有病理学意义，并可能在儿童期或成年期引起各种临床表现。在包括超声、计算机断层扫描（CT）和磁共振（MR）成像在内的各种成像方式中早期识别这些病变，对于做出正确诊断进而避免不必要的额外检查具有重要价值。为了区分这些病变，了解胰腺的胚胎发育和正常解剖结构至关重要。在本文中，我们回顾了胰腺的胚胎学和正常解剖结构，以及各种胰腺成像方式中发育异常和解剖变异的诊断陷阱。
