The portal vein derives from the vitelline veins, a component of the extraembryonic venous system, and is normally formed by the confluence of the superior mesenteric and splenic vein. The knowledge of the anatomy of the portal vein and its abnormalities is important for interventional and surgical procedures. Variant portal architecture is a common finding during imaging studies. Ultrasonography, computed tomography and magnetic resonance are non-invasive methods for studying and understanding portal vein's anatomy and abnormalities. We describe a rare case of variation in the formation and course of the portal vein. To the best of our knowledge, there is no evidence of this kind of abnormality in literature.
门静脉起源于卵黄静脉，后者是胚外静脉系统的一个组成部分，通常由肠系膜上静脉和脾静脉汇合而成。了解门静脉的解剖结构及其异常情况对于介入和外科手术很重要。门静脉结构变异在影像学检查中是常见发现。超声、计算机断层扫描和磁共振成像都是用于研究和了解门静脉解剖结构及异常情况的非侵入性方法。我们描述了一例罕见的门静脉形成和走行变异病例。据我们所知，文献中尚无此类异常情况的报道。
