目的：本研究的目的是描述胰腺导管内管状乳头状肿瘤的影像学表现。方法：回顾性收集11例经病理证实为导管内管状乳头状肿瘤的胰腺肿瘤。对动态对比增强计算机断层扫描（CT）、磁共振（MR）成像（包括磁共振胰胆管造影（MRCP））、超声和内镜逆行胰胆管造影（ERCP）结果进行了回顾。 2 音导管征和酒瓶软木塞征分别作为 CT/MR 和 MRCP/ERCP 图像上导管内肿瘤生长的指标进行审查。结果：在动态 CT 图像（7/10，70%）和 MR 成像（5/8，63%）上注意到 2 音导管征。除了一名有分支管病变的患者外，所有患者的远端主胰管均扩张。在 MRCP 图像（3/8，38%）和 ERCP 图像（3/6，50%）上观察到酒瓶塞征。结论：导管内管状乳头状肿瘤是罕见的肿瘤，表现出特征性影像学表现，例如代表其导管内生长的 2 音导管征和酒瓶塞征。
Objective: The objective of this study was to describe the imaging findings for intraductal tubulopapillary neoplasms of the pancreas.Methods: Eleven pancreatic tumors pathologically confirmed as intraductal tubulopapillary neoplasm were retrospectively collected. The dynamic contrast-enhanced computed tomography (CT), magnetic resonance (MR) imaging including MR cholangiopancreatography (MRCP), ultrasound, and endoscopic retrograde cholangiopancreatography (ERCP) results were reviewed. The 2-tone duct sign and cork-of-wine-bottle sign were reviewed as indicators of intraductal tumor growth on CT/MR and MRCP/ERCP images, respectively.Results: A 2-tone duct sign was noted on the dynamic CT images (7/10, 70%) and on the MR imaging (5/8, 63%). The distal main pancreatic duct was dilated in all the patients except one, who had a branch duct lesion. A cork-of-wine-bottle sign was observed on the MRCP image (3/8, 38%) and on the ERCP image (3/6, 50%).Conclusions: Intraductal tubulopapillary neoplasms are rare tumors showing characteristic imaging findings such as the 2-tone duct sign and the cork-of-wine-bottle sign that represent their intraductal growth.
