Infant with soft tissue prominence in the neck area,
compressible and not painful.
MRI (see below): T2 weighted coronal images show
a typical mixed form (macrocystic and microcystic) lymphatic
malformation (low-flow vascular birthmark). These lesions
are commonly called cystic hygroma. Please note that there
is signal abnormalities in the lower section of the tongue.
Tongue involvement is relatively common in lymphatic
malformations of the head and neck. These low-flow
malformations do not demonstrate contrast enhancement on
post-contrast scans (not shown).
