偶然发生的胰腺囊性病变是诊断放射科医生遇到的常见挑战。具体而言，考虑到良性胰腺囊性病变的普遍存在，确定何时建议采取积极措施（例如手术切除或内窥镜超声取样）很困难。在本文中，我们回顾了胰腺囊性病变的常见类型，包括浆液性囊腺瘤、导管内乳头状粘液性肿瘤和粘液性囊性肿瘤，并附有每种类型的影像学实例。我们还讨论了需要转诊给外科医生或内窥镜医师的高风险或令人担忧的影像学特征，并提供了这些特征的几个例子。这些影像特征符合国际共识指南、美国胃肠病学协会 (2015)、美国胃肠病学会 (2018)、美国放射学会 (2010、2017) 和欧洲指南 (2013、2018) 的最新指南。我们的重点文章解决了处理偶发囊性胰腺病变的影像学困境，权衡影像学随访和积极干预措施之间的选择。版权所有 © 2024 韩国放射学会。

Incidental pancreatic cystic lesions are a common challenge encountered by diagnostic radiologists. Specifically, given the prevalence of benign pancreatic cystic lesions, determining when to recommend aggressive actions such as surgical resection or endoscopic ultrasound with sampling is difficult. In this article, we review the common types of cystic pancreatic lesions including serous cystadenoma, intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm with imaging examples of each. We also discuss high-risk or worrisome imaging features that warrant a referral to a surgeon or endoscopist and provid several examples of these features. These imaging features adhere to the latest guidelines from the International Consensus Guidelines, American Gastroenterological Association (2015), American College of Gastroenterology (2018), American College of Radiology (2010, 2017), and European Guidelines (2013, 2018). Our focused article addresses the imaging dilemma of managing incidental cystic pancreatic lesions, weighing the options between imaging follow-up and aggressive interventions.Copyright © 2024 The Korean Society of Radiology.
