There is a well-defined thick-walled cystic mass lesion with mural calcification and internal crumpled membranes in segment VII.
Case Discussion
Hydatid cysts at later stages (inactive/degenerative) may not have really anechoic appearance on ultrasonography and can be challenging. MRI can be helpful in such cases when available.
