A 40-year-old HBV positive male patient underwent routine abdominal ultrasonography that showed small left hepatic focal lesion. A A small left lobar segment II focal lesion is seen measuring about 2.3 cm eliciting high T2 signal. B axial diffusion and C ADC images show facilitated diffusion with DWI-ADC value 2.22 × 10−3 D Axial DTI gray scale image, E DTI-ADC map and F FA map: the DTI-ADC value was 2.21 and the FA value was low = 0.26 suggestive of benign nature. G non-contrast T1 H arterial phase and I delayed phase of the dynamic study showed nodular enhancement that progress into complete filling in the delayed phase, and imaging features were compatible with hemangioma. The lesion was categorized as LR-1
