Ectopic pancreas within the mesentery is rare. In this case report, a 61-year-old man with an ectopic pancreas within the jejunal mesentery for over 20 years developed chronic pancreatitis that progressed to acute exacerbation. Our computed tomography (CT) performed for acute abdomen assessment suggested acute appendicitis or Meckel's diverticulitis. However, a CT scan taken 20 years ago revealed a structure indicative of an ectopic pancreas in the mesentery, and further imaging findings taken 10 and 4 years ago confirmed progression to chronic pancreatitis. Furthermore, we found a pancreatic stone confined in the luminal structure that corresponded to the main pancreatic duct; this stone eventually caused acute exacerbation. In summary, we report a case of mesenteric ectopic pancreas that showed typical findings of progression and acute exacerbation of chronic pancreatitis on CT.
肠系膜内的异位胰腺较为罕见。在本病例报告中，一名61岁男性，其空肠系膜内存在异位胰腺超过20年，并发慢性胰腺炎并进展为急性加重期。我们为评估急腹症而进行的计算机断层扫描（CT）提示为急性阑尾炎或梅克尔憩室炎。然而，20年前的CT扫描显示肠系膜内有一个提示异位胰腺的结构，10年前和4年前的进一步影像学检查结果证实已进展为慢性胰腺炎。此外，我们在与主胰管相对应的管腔结构中发现了一枚胰石；这块结石最终导致了急性加重。总之，我们报告了一例肠系膜异位胰腺病例，其在CT上显示出慢性胰腺炎进展及急性加重的典型表现。
