摘要
目的探讨胰腺脂肪替代(fatty replacement of pancreas)的CT表现及临床意义。方法收集CT发现胰腺脂肪替代患者3例的资料。CT扫描包括平扫、动脉期及门静脉期,观察胰腺各部的形态、大小、密度、胰腺小叶及小叶间隔、胰管走行的显示情况,确定脂肪替代的部位,并结合临床资料及实验室检查结果分析其临床意义。结果①CT表现:完全性脂肪替代2例(胰头前后分、颈、体、尾),大部分脂肪替代1例(胰头前分、颈、体);2例胰腺形态均规整,1例欠规整;2例胰腺体积稍大,1例胰腺体积正常;3例小叶间隔均增宽及胰腺小叶均萎缩;3例主胰管及分支均无狭窄梗阻。②临床情况:3例患者均有慢性腹泻,2例合并糖尿病(其中1例还合并胆总管炎伴慢性梗阻),另1例合并胆总管小结石,3例血清脂肪酶及1例血清淀粉酶降低。结论胰腺脂肪替代的CT表现有一定的特征性,常合并有胰腺内、外分泌功能不足的临床表现。
Objective To investigate the CT imaging features of pancreatic fatty replacement and its clinical significance. Methods Three patients with pancreatic fatty replacement detected by CT were retrospectively analyzed. CT examination included plain scan and contrast-enhanced scanning at the arterial and portal venous phases. The shape, size, density, pancreatic lobulation and interlobular spaces, course of the pancreatic duct were carefully observed. The clinic and laboratory data were also analyzed to determine the clinical significance of pancreatic fatty replacement. Results ① Imaging features： Two patients had complete fatty replacement involving the entire pancreas, another one had most fatty replacement sparing the posterior aspect of head and tail. Two patients had regular configuration of pancreas. The size of pancreas was slightly enlarged in 2 patients. Lobular atrophy and widening of interlobular spaces were present in all 3 patients. The pancreatic duct was normal in 3 patients. ②Clinic findings： Chronic diarrhea was present in 3 patients. Two pattens had diabetes （one had chronic cholangitis with choledochal lithiasis）, another one had small stone in the common bile duct. Serum lipase was low in 3 patients, of which one had low serum amylase. Conclusion Pancreatic fatty replacement demonstrates certain characteristic CT appearances, and is usually associated with disturbances of both the endocrine and exocrine functions of the pancreas.
