A 52-year-old woman with EHE. The nonenhanced CT scan (a) reveals multiple ill-defined homogeneous hypoattenuated lesions. The lesions demonstrate marginal enhancement in the arterial phase (b) and heterogeneous progressive centripetal enhancement in the portal vein (c). The MRI scan (d, T1WI in-phase; e, fat-suppressed T2WI; f, DWI; g, ADC map) shows hypointensity on T1WI, hyperintensity on T2WI and high signal intensity on DWI and the ADC map. The enhancement pattern on dynamic contrast-enhanced MRI (h, arterial phase; i, portal venous phase; j, delayed phase) corresponds with that on CT. The lesion presents with the halo sign (black arrow) and lollipop sign (white arrow)
