Ultrasound Finding:

• Sometimes the liver contains multiple parent cysts in both lobes of the liver; the cyst with the thick walls occupies a different part of the liver.
  
• The tissue between the cysts indicates that each cyst is a separate parent cyst and not a daughter cyst.
  
• If a daughter cyst is found, it is specific for echinococcal disease.
  
  
  

Ultrasound Finding: 

• On ultrasound, several patterns may occur, from a simple cyst to a complex mass with acoustic enhancement. 
• The shape may be oval or spherical, with regularity of the walls. Calcifications may occur. 
• Septations are very frequent and include honeycomb appearance with fluid collections; "water lily" sign, which shows a detachment and collapse of the germinal layer; or "cyst within a cyst."
