19 week fetus of a 26 year old gravid female with a referring diagnosis of hydrocephalus.


Within the markedly enlarged cranial vault, a large solid and cystic mass was identified. US showed vascularity in the solid components of the mass, and foci of increased echogenicity, possibly calcifications (white arrow). MR showed the extent of the mass to better advantage. Only a small amount of normal appearing brain parenchyma was noted along the convexity (yellow arrow). Cardiomegaly and hepatomegaly was apparent.




Teratomas are tumors composed of all three germ cell layers and represent 25-35% of all neonatal tumors. They can be found from the head to the pelvis, most commonly along the sacrococcygeal region. Teratomas of the head and neck represent approximately 6 to 10% of all teratomas, most commonly found in the cervical region. Perinatal mortality and morbidity is high because of high output cardiac failure, preterm delivery, anemia and tumor rupture.
