The water lily sign denotes which hepatic lesion?

The water lily sign reflects floating membranes inside a hepatic hydatid cyst. It occurs when the endocyst membrane detaches from the cyst wall and becomes free-floating in the cyst fluid, giving the appearance of floating membranes like petals on a water lily. This is characteristic of echinococcal disease (hydatid cyst) in the liver. Other hepatic lesions, such as a liver abscess or a hemangioma, do not produce this floating-membrane sign.
