A 60-year-old male patient with positive HBV presented with jaundice. He underwent abdominal ultrasonography that showed liver cirrhosis and right hepatic lobe lesion. A Axial T2 image shows large mass lesion is seen infiltrating almost whole right lobe roughly measuring about 15.5 cm eliciting high T2 signal. B axial diffusion and C ADC images show mild diffusion restriction with DWI-ADC value 1.25 D Axial DTI gray scale image, E DTI-ADC map and F FA map: the DTI-ADC value was 1.12 (much lower than conventional ADC) and the FA value was high = 0.45. G non-contrast T1 H arterial phase and I delayed phase of the dynamic study showed heterogenous progressive delayed enhancement of the lesions. The lesion was categorized as LR-M. True cut biopsy was done and the pathology result was cholangiocarcinoma
