Prenatal diagnosis of soft-tissue malformations by ultrasound and X-ray.

This study presents four cases of fetal soft-tissue malformations diagnosed during pregnancy by ultrasonic scanning and amniography. The series comprises two fetal teratomas, one case of fetal ascites, and one case of a partial mole with coexistent fetus. Diagnostic and differential diagnostic problems are illustrated by a fifth case where the final diagnosis was a big maternal ovarian cyst-adenoma coexistent with a normal fetus.
