the following is from the above link.
Cystic hygroma colli probably represent the most common cause for a neck mass detected prenatally. Other neck masses detectable ultrasonically include cervical meningomyelocele, hemangioma, teratoma, goiter, sarcoma, and metastatic adenopathy. Occasionally, a large cephalocele may mimic a neck mass. In most of these rare cases, polyhydramnios, hydrops fetalis, or other clinical features signal a careful search of the fetal neck.
Is an abnormal neck mass present?
1. Is the mass unilateral or bilateral, posterior or anterior ?
2. Is the mass in the midline or not ?
3. What are its echotexture and Doppler characteristics ?
* most bilateral posterior masses are cystic hygroma colli, especially multicystic masses with a midline septation.
* most unilateral anterior masses are teratomas
* most bilateral anterior masses are goitre
* hemangiomas can occur anywhere with variable echotexture, but have typical arterial and venous Doppler signal.
