Atrial cholangiocarcinoma diagnosed by cardiac magnetic resonance imaging

Abstract

[eng] In this rare case of intrahepatic cholangiocarcinoma (ICC) tumor thrombus with right atrial (RA) invasion, we describe its diagnostic workup based on cardiac magnetic resonance imaging (cMRI). An 85-year-old man underwent transthoracic echocardiography due to dyspnea, revealing a RA mass. Comprehensive cMRI evaluation, including cine bright blood, T1- and T2-weighed, fat-suppressed, and contrast-enhanced imaging, was performed and diagnosis of ICC tumor thrombus with RA invasion was made. This first description of cMRI-guided diagnosis of RA invasion by ICC tumor thrombus points out the usefulness of cMRI for the diagnostic approach of RA masses suggestive of tumor thrombus.
