Cystic hygroma presents sonographically as which of the following features?

Explanation:
Cystic hygroma is a congenital lymphatic malformation that typically presents in the neck. On ultrasound, it appears as a multiloculated, anechoic (dark) cystic mass with thin internal septations or membranes surrounding the fluid-filled spaces. This characteristic septated, fluid-filled neck lesion distinguishes it from other neck masses that are solid or contain calcifications, or from cystic lesions in other organs like the liver or chest. So the described finding—a multiloculated anechoic cervical mass with a thin surrounding membrane—best matches cystic hygroma.
