These are 2 cases in which an early examination revealed an abdominal cyst (some with other associated findings), and in all cases the cysts disappeared and the newborns were considered normal on physical examinations and follow-up.

Case #1:

Primigravida, 23 years old

13 weeks

Abdominal thick wall cyst confused as a megabladder

Chorionic villus biopsy :46XX normal


19 weeks

1 week after total cyst aspiration. (Fluid: few epithelial cells+ lymphocytes)

Normal intestinal pattern.


26 weeks

Normal growth and amniotic fluid

Abdominal calcifications


38 weeks

normal growth and amniotic fluid.

Calcifications with shadow.

This presumably could represent an early meconium peritonitis, but the follow-up of the baby after birth is normal.


Case #2:

This is a 11 weeks 5 days fetus with a large abdominal cyst and an increased nuchal lucency of 4.3 mm. An early amniocentesis was performed at 12 weeks with normal karyotype. At 14 weeks 2 days a small cyst was seen next to the stomach, and by 20 weeks there was no trace left of the cyst. The postnatal follow-up up to 2 years is unremarkable.



14 weeks 2 days exam: only a small cyst is seen next to the stomach


It was suspected, but not proven, that this cyst had a lymphatic origin.

Although the nature of those cysts is undetermined, these cases points to the fact that at least occasionally the presence of even a large cystic structure may not have much influence on the fetus.
