Pathways of Extrapancreatic Perineural Invasion by Pancreatic Adenocarcinoma: Evaluation With 3D Volume-Rendered MDCT Imaging

Abstract

OBJECTIVE: The purpose of this article is to familiarize radiologists with the common pathways of extrapancreatic perineural invasion of pancreatic adenocarcinoma and to highlight the potential value of 3D volume-rendered MDCT in its diagnosis. CONCLUSION: The perineural plexuses closely follow peripancreatic vessels, which are well depicted by contrast-enhanced 3D volume-rendered imaging, thus facilitating the diagnosis of extrapancreatic perineural invasion of pancreatic adenocarcinoma.
