Abstract
PURPOSE
This study aims to compare tubular pancreatic ductal adenocarcinoma (tPDAC) and colloid subtype pancreatic ductal adenocarcinoma (cPDAC) associated with intraductal papillary mucinous neoplasms (IPMNs) on computed tomography.
METHODS
An institutional review board-approved retrospective study included patients with either IPMN tPDAC or cPDAC. Enhancing mural nodules (MN), solid component (SC), main pancreatic duct (MPD) diameter, and abrupt change in MPD caliber were evaluated.
RESULTS
A total of 22 patients with cPDAC and 17 patients with tPDAC showed no significant difference in MPD size. MN and SC were seen in cPDAC/tPDAC in 55%/18% and 9%/53%, respectively. Abrupt change in MPD caliber was seen in cPDAC/tPDAC at 18%/59%.
CONCLUSION
cPDAC and tPDAC differ in the frequency of MN, SC, and changes in MPD caliber.
摘要
目的
本研究旨在通过计算机断层扫描比较与导管内乳头状黏液性肿瘤（IPMN）相关的管状胰腺导管腺癌（tPDAC）和黏液亚型胰腺导管腺癌（cPDAC）。
方法
一项经机构审查委员会批准的回顾性研究纳入了IPMN tPDAC或cPDAC患者。评估强化壁结节（MN）、实性成分（SC）、主胰管（MPD）直径以及MPD管径的突然变化。
结果
22例cPDAC患者和17例tPDAC患者的MPD大小无显著差异。MN和SC分别在55%的cPDAC/18%的tPDAC以及9%的cPDAC/53%的tPDAC中可见。MPD管径突然变化在18%的cPDAC/59%的tPDAC中可见。
结论
cPDAC和tPDAC在MN、SC的发生率以及MPD管径变化方面存在差异。
