It represents a mucin-producing tumor that originates from the ductal epithelium and can evolve from slight dysplasia to invasive carcinoma. In addition, different aspects of tumor progression may be seen in the same lesion. Three types are recognized, the branch duct variant, the main duct variant, which shows a much higher prevalence for malignancy, and the mixed-type variant, which combines branch and main duct characteristics. Advances in cross-sectional imaging have led to an increased rate of IPMN detection. The main imaging characteristic of IPMN is the dilatation of the pancreatic duct without the presence of an obstructing lesion. The diagnosis of a branch duct IPMN is based on the proof of its communication with the main pancreatic duct on MRI-MRCP examination. Early identification by imaging of the so-called worrisome features or predictors for malignancy is an important and challenging task. In this review, we will present recent imaging advances in the diagnosis and characterization of different types of IPMNs, as well as imaging tools available for early recognition of worrisome features for malignancy. A critical appraisal of current IPMN management guidelines from both a radiologist\u2019s and surgeon\u2019s perspective will be made. Special mention is made of complications that might arise during the course of IPMNs as well as concomitant pancreatic neoplasms including pancreatic adenocarcinoma and pancreatic endocrine neoplasms. Finally, recent research on prognostic and predictive biomarkers including radiomics will be discussed.<\/jats:p>","DOI":"10.3390\/diagnostics13122015","type":"journal-article","created":{"date-parts":[[2023,6,9]],"date-time":"2023-06-09T08:37:33Z","timestamp":1686299853000},"page":"2015","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Intraductal Papillary Mucinous Neoplasm of the Pancreas: A Challenging Diagnosis"],"prefix":"10.3390","volume":"13","author":[{"given":"Charikleia","family":"Triantopoulou","sequence":"first","affiliation":[{"name":"Department of Radiology, Konstantopouleio General Hospital, 14233 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofia","family":"Gourtsoyianni","sequence":"additional","affiliation":[{"name":"1st Department of Radiology, School of Medicine, National and Kapodistrian University of Athens, Areteion Hospital, 11528 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitri\u03bfs","family":"Karakaxas","sequence":"additional","affiliation":[{"name":"Department of Surgery, Konstantopouleio General Hospital, 14233 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Spiros","family":"Delis","sequence":"additional","affiliation":[{"name":"Department of Surgery, Konstantopouleio General Hospital, 14233 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e5535","DOI":"10.1097\/MD.0000000000005535","article-title":"Incidental pancreatic cystic neoplasms in an asymptomatic healthy population of 21,745 individuals: Large-scale, single-center cohort study","volume":"95","author":"Chang","year":"2016","journal-title":"Medicine"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Gourtsoyiannis, N.
