The contrast between CT imaging and pathological findings in perihilar cholangiocarcinoma

Abstract

Although surgical resection provides the only chance of cure for perihilar cholangiocarcinoma, it easily invades to around organs such as liver, pancreas, portal vein or hepatic artery by longitudinal and radial spreads. Aggressive resection improves treatment outcome, but it tends to be high invasive surgery with combined resection of around organs. Therefore it is very important to determine the surgical indication or operative procedure by accurate preoperative diagnosis for longitudinal and radial extension.

Multidetector-row CT (MDCT) has high spatial and time resolution. We can make multiplanar reformat imaging or three dimension imaging from volume data of MDCT. Herein I show the delineation and diagnosis for longitudinal and radial extension in perihilar cholangiocarcinoma by MDCT with the contrast between CT imaging and pathological findings.
