11. Comment
● The water-lily sign, also known as the
camalote sign, is seen in hydatid
infections when there is detachment of
the endocyst membrane which results in
floating membranes within the pericyst
that mimic the appearance of a water lily.
This sign is pathognomonic of intra-
bronchial rupture of PHC.
