Figure 1. MRI and US findings of the intraabdominal lesion. (A) MRI at 2 months of age, a pure cystic lesion. (B) US of the abdomen at 3 months of age showing a vague small solid component within 1 of the bilobulated cysts of 25×25×9 mm and 28×27×13 mm in diameter. (C) CT at 6 months of age showing a 50×40×36 mm solid component within a 104×61×48 mm cystic lesion connecting with a 2-cm stalk. Please note that this image has a striking similarity to a prenatal US image of a fetus.
