Pancreas divisum is a common congenital abnormality of the pancreas that results from the lack of fusion between the dorsal and ventral pancreatic ducts during foetal development. In these cases, the dorsal duct becomes the main pancreatic duct and drains most of the pancreas. Pancreas divisum is mainly asymptomatic, but the prevalence of pancreas divisum is higher in patients with chronic abdominal pain and idiopathic pancreatitis. A study of 20 patients with pancreas divisum (12 men and eight women; aged 19-77 years; mean age 39 years) and who underwent magnetic resonance cholangiopancreatography (MRCP), was performed. In our series, pancreas divisum was clinically manifested as unexplained episodes of abdominal pain (mean duration 3.2 years) (60 percent), mild pancreatitis (30 percent) or incidentally (ten percent). MRCP demonstrated non-communicating dorsal and ventral ducts, independent drainage sites, a dominant dorsal pancreatic duct, and a small cystic dilatation of the dorsal duct at minor papilla (santorinocoele). In this pictorial essay, we review the most common MRCP features of pancreas divisum.
胰腺分裂是一种常见的胰腺先天性异常，由胎儿发育期间背侧和腹侧胰管缺乏融合所致。在这些病例中，背侧胰管成为主胰管并引流大部分胰腺。胰腺分裂主要无症状，但在慢性腹痛和特发性胰腺炎患者中，胰腺分裂的患病率较高。对20例胰腺分裂患者（12例男性和8例女性；年龄19 - 77岁；平均年龄39岁）进行了一项研究，这些患者均接受了磁共振胰胆管造影（MRCP）检查。在我们的系列研究中，胰腺分裂临床表现为不明原因的腹痛发作（平均持续时间3.2年）（60%）、轻度胰腺炎（30%）或偶然发现（10%）。MRCP显示背侧和腹侧胰管不连通、独立的引流部位、占主导地位的背侧胰管以及背侧胰管在小乳头处的小囊性扩张（桑托里尼囊肿）。在这篇图谱文章中，我们回顾了胰腺分裂最常见的MRCP特征。
