We aimed to describe CT signs useful for differentiation of distal agenesis from distal or dorsal pancreas lipomatosis. Multidetector CT (MDCT) studies of five patients with distal pancreas agenesis (n = 2), distal lipomatosis (n = 1), distal short pancreas (n = 1), and distal pancreatectomy (n = 1) were retrospectively reviewed. Agenesis of dorsal pancreas can be diagnosed by the absence of body and tail of pancreas. In the absence of distal pancreas, distal pancreatic bed can be filled by stomach or intestine (dependent stomach or dependent intestine signs), which abut splenic vein. Same findings can be seen in patients with distal pancreatectomy, however, splenic vein is absent in these patients. In case of distal lipomatosis abundant fat tissue is observed anterior to splenic vein. Dependent stomach and/or dependent intestine signs on MDCT imaging can allow differentiation of distal pancreas agenesis from distal lipomatosis obviating further diagnostic studies.
我们旨在描述有助于区分胰腺远端发育不全与胰腺远端或背侧脂肪瘤病的CT征象。对5例胰腺远端发育不全（n = 2）、远端脂肪瘤病（n = 1）、远端短胰腺（n = 1）和远端胰腺切除术（n = 1）患者的多排螺旋CT（MDCT）研究进行回顾性分析。胰腺背侧发育不全可通过胰腺体尾部缺如进行诊断。在无胰腺远端的情况下，远端胰腺床可被胃或肠填充（胃下垂或肠下垂征），胃或肠与脾静脉相邻。胰腺远端切除术后的患者也可出现相同表现，然而，这些患者的脾静脉缺如。在胰腺远端脂肪瘤病的情况下，脾静脉前方可见大量脂肪组织。MDCT成像上的胃下垂和/或肠下垂征可用于区分胰腺远端发育不全与远端脂肪瘤病，无需进一步的诊断性检查。
