CT and T1- and T2-weighted images. CT showing a multilocular cystic lesion in the medial segment of the liver with calcification in the cyst wall (a). Thickening of the cyst wall around the calcification (b). Contrast-enhanced CT showed no enhancement of the thickened wall (a, b). The cystic lesion was visualized as a hypointensity on T1-weighted images (c) and as a hyperintensity on the T2-weighted images (d).
