Images of the intrahepatic cysts. a: Full abdominal CT with enhanced arterial phase shows no enhancement of infected cysts. b: FDG metabolism in the cyst wall of the larger cyst of the left liver was slightly increased. c: MRI examination of the T2-stage cross-section showed that the size of the left liver cyst was about 8.9 × 8.8 × 9.0 cm. T2 lipo-pressurization sequence showed that the lesion had a band-like high-intensity shadow, and the cyst wall was slightly thickened. d: MRI examination of the T2 sagittal plane. There was a separation within the cyst, as indicated by the arrow
