Pancreatic cystic lesions and the role of contrast enhanced endoscopic ultrasound.

Clin Radiol 2022 06 3;77(6):418-427. Epub 2022 Apr 3.

Department of Radiology, Addenbrooke's Hospital, Cambridge University Hospitals NHS Foundation Trust, Hills Road, Cambridge, CB2 2QQ, UK.

An exponential rise in the use of cross-sectional imaging has led to an increase in the incidental identification of pancreatic cystic lesions (PCL); however, with many subtypes defined to date and heterogeneous morphology with often absent defining radiological features, PCLs present a diagnostic challenge. Computed tomography (CT) and/or magnetic resonance imaging (MRI) alone are frequently not sufficient to provide accurate characterisation. Endoscopic ultrasound (EUS) has an important role in the evaluation and classification of PCLs through its ability to define the internal architecture, which is further enhanced by the use of contrast medium.

[Intraductal neoplasms of the pancreas].

Pathologe 2021 Sep 17;42(5):472-483. Epub 2021 Aug 17.

Institut für Pathologie, Universitätsmedizin der Johannes Gutenberg-Universität Mainz, Mainz, Deutschland.

The latest WHO classification of tumors of the digestive system (2019) has introduced new concepts for the stratification of intraductal neoplasms of the pancreas, mostly based on molecular genetics and malignant potential. Among them, pancreatic intraepithelial neoplasias (PanINs) and intraductal papillary mucinous neoplasms (IPMN) are both precursors of pancreatic ductal adenocarcinoma, whereas intraductal oncocytic papillary neoplasms (IOPN) and intraductal tubulopapillary neoplasms (ITPN) are usually associated with less aggressive subtypes of pancreatic cancer and therefore have a much better prognosis. Hence, it is of utmost importance to correctly classify these lesions and to distinguish them from each other as well as from other nonductal types of neoplasms, which can rarely display an intraductal growth, such as neuroendocrine tumors and acinar cell carcinomas.
