IV contrast showed a hepatic hydatid cyst with water lily sign in the right lobe of the liver with a compressive effect on the adjacent diaphragm and the left lobe of the liver and hydatid cyst of the bladder dome (Figure 1). In axial sections of the CT scan, hepatic hydatid cysts were seen with water lily sign and pressure effect on the diaphragm and an intact capsule in the right and the left lobes of the liver.
