We present a case of bile duct adenoma that mimicked hepatic metastasis from gastric cancer. The adenoma exhibited prolonged enhancement on dynamic computed tomography, hyperintensity on diffusion-weighted imaging, and diminished uptake of superparamagnetic iron oxide and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid on magnetic resonance imaging, resembling those of adenocarcinomas. Knowledge of the imaging findings of this rare entity may aid correct diagnosis.
