Patient Data

Age: 3 years
Gender: Male

MRI neck

A cystic lesion is noted in the left posterior cervical space, deep to the sternomastoid, and measuring 4 x 4 x 6 cm. It shows fine internal septations, and water-like signal in all pulse sequences. One of the locules (inferior) shows high T1 signal suggestive of proteinaceous or hemorrhagic content. No post Gadolinium enhancement. No cervical lymphadenopathies. The other neck spaces are unremarkable.

Case Discussion

Cystic hygroma / lymphangioma is a type of lymphatic malformations that appears as an insinuating multiloculated cystic mass at superficial and deep neck spaces (transpatial). Being infrahyoid, a posterior location is more common. It can show fluid/fluid levels. High T1 fluid content reflects hemorrhagic or proteinaceous nature.
