Intraductal oncocytic papillary neoplasm of the pancreas: a radio-pathological case study


Fischer, M A; Donati, O; Heinrich, S; Weber, A; Hany, T F; Soldini, D; Alkadhi, H; Marincek, B; Scheffel, H (2010). Intraductal oncocytic papillary neoplasm of the pancreas: a radio-pathological case study. Journal of the Pancreas, 11(1):49-54.

Abstract

CONTEXT: An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor with the potential of developing invasive carcinoma. Its differentiation from other cystic-like neoplasms of the pancreas, such as intraductal papillary mucinous neoplasms, is a challenge for pancreatic imaging. CASE REPORT: We present the case of a 76-year-old male with painless jaundice caused by an intraductal oncocytic papillary neoplasm of the pancreas. The imaging findings on computed tomography, magnetic resonance including diffusion-weighted imaging, and (18)F-fluorodeoxyglucose positron emission tomography are presented and the radio-pathological correlations are discussed. CONCLUSION: An intraductal oncocytic papillary neoplasm of the pancreas appears as a cystic tumor communicating with the dilated pancreatic duct featuring intraductal tumor nodules. Intraductal oncocytic papillary neoplasms show a high (18)F-fluorodeoxyglucose-uptake in positron emission tomography and low diffusion values in diffusion-weighted imaging including apparent diffusion coefficient maps which may be a valuable attribute in distinguishing these rare lesions from intraductal papillary mucinous neoplasms.
