•Hepatic hydatid disease is a parasitic zoonosis caused by the Echinococcus tape worm. In the liver, two agents are recognised as causing disease in the human: Echinococcus granulosus Echinococcus multilocularis •In the human manifestation the disease caused by echinococcus is most commonly localized to liver (in 75% of cases), followed by lungs (in 5–15% of cases) and other organs in the body such as the spleen, brain, heart, and kidneys (in 10–20% of cases). •If the patient has cysts in the liver, symptoms abdominal discomfort, hepatomegaly with an abdominal mass, jaundice, fever and/or anaphylactic reaction. Radiographic features: •Plain radiograph: Shows a curvilinear or ring calcific shadow overlying the liver due to calcification of the pericyst. •Ultrasound: Multiseptate cyst with “daughter” cysts and echogenic material between cysts. •CT scan: Septation and daughter cysts may be visualised. The water-lily sign indicates a cyst with floating, undulating membrane, caused by a detached endocyst. It may also show hyperdense internal septa representing a spoke wheel pattern within a cyst.
