A placental teratoma is a very rare placental tumor.
Pathology
A placental teratoma is benign and almost never associated with congenital deformities in the fetus.
Radiographic features
Ultrasound
May show a heterogeneous mass at the placental margin. Hyperechoic foci consistent with fat may be present 1. A normal fetus is often seen in separation.
There is usually a lack of structural organization and lack of large vessels entering the tumor 4.
Differential diagnosis
Consider
acardiac fetus - acaidiac amorphus
