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.

A 50-year-old male presented gradually growing pancreatic body mass. An abdominal computed tomography showed a 9.9-cm mass, larger than the 8.9-cm mass one year ago. As the patient did not have complaints for any symptomatic problems, the gastroenterologist decided to check it with regular follow-up. However, as the tumor grew faster than expected, the patient was recommended for surgical resection. Laparoscopic pylorus preserving pancreaticoduodenectomy was done. Since the tumor abutted to the superior mesenteric vein and the portal vein, wedge resection of vessel was inevitable. Pathology was serous cystadenoma. The patient was discharged without postoperative complications. Herein, we report this case with asymptomatic large serous cystic neoplasm treated by laparoscopic approach. The appropriateness of current guidelines for surgery in serous cystic neoplasm is also discussed.

Mucious cystic neoplasm of pancreas is a cystic neoplasm composed of columnar, mucin-producing epithelium and is supported by ovarian-type stroma. The key to the cytologic evaluation of pancreatic cystic lesions is to recognize the cytologic components as being diagnostic of a mucin-producing cystic neoplasm, as all of these neoplasms need to be resected. We report the use of fine needle aspiration cytology in the diagnosis of an invasive mucinous cystic carcinoma confirmed by partial pancreatectomy. The cytologic specimen showed a abundant mucin background and sheets or papillae of neoplastic cells. There are mucin-containing columnar cells that show a variable degree of cytologic atypia.

Although many guidelines for pancreatic cystic neoplasms focus on the management of intraductal papillary mucinous neoplasm of the pancreas (IPMN) at the highest oncological risk, there are many issues that surgeons need to consider at the time to plan the surgical procedures based on characteristics of IPMN subtypes, such as multiplicity of branch duct-IPMN (BD-IPMN) and intraductal spreading of main duct-IPMN (MD-IPMN). For multifocal BD-IPMN, partial pancreatectomy would be selected to remove BD-IPMN with predictors of malignancy, while the other lesions without risk factors can be left, although total pancreatectomy might be considered if the patients have a strong family history of pancreatic cancer. Partial pancreatectomy would be also adequate procedure for MD-IPMN if negative surgical margin for high-grade dysplasia or invasive carcinoma were achieved. It has become to be well-known that patients with BD-IPMN are at increased risk for developing not only IPMN-associated pancreatic ductal adenocarcinoma (PDAC) but also PDAC independent from the IPMN. Hence, the detection of a concomitant PDAC is also an important focus for strategies after resection of BD-IPMNs. Our recent analysis of patients after partial pancreatectomy for MD-IPMN with negative surgical margin identified an unexpected recurrence pattern, which we called "monoclonal skip" recurrence. MD-IPMN seems to be disseminated in the pancreatic ductal systems and MD-IPMN with identical genetic background was detected in the remnant pancreas even in a long time after index surgery. We proposed strategies of postoperative surveillance based on characteristics and natural history of each morphological subtype.

Solid and papillary epithelial neoplasm (SPEN) of the pancreas is a rare tumor with low malignant potentiality that usually occurs in young females. Preoperative evaluation, especially radiologic tests, including ultrasonography and CT scan, is helpful in the diagnosis. These studies demonstrate a well-demarcated large mass with solid and cystic portions, frequently in the tail or body of the pancreas. Complete resection is usually curative, however local invasion and/or metastasis may occur. The authors report a case of a solid and papillary epithelial neoplasm of the pancreatic body in a 14-year old child at St. Benedict Hospital and review the literature.
