A 66-year-old man with multiple fat-containing hydatid cysts in the liver. a Axial gradient-echo in-phase T1-weighted MR image shows multiple high signal intensity foci (arrows) within hepatic hydatid cyst. b Axial gradient-echo opposed-phase T1-weighted MR image shows macroscopic fat within the same lesions, a finding confirmed by chemical shift artifact and signal cancelation (arrows) surrounding the lipid pure component
