SPR 2019 Fetal Course SAM Session - Session 4

Thursday, September 12th

Question Title

* 1. Regarding lateral ventricular size of the fetal brain, measured at the atria, which of the following is true?

There is a steady increase in size throughout the course of pregnancy.

There is a steady decrease in size throughout the course of pregnancy.

There is an increase in size during the first half of pregnancy and decrease in size during the second half.

It remains relatively constant in size from 14 to 40 weeks’ gestation.

Question Title

* 2. Ventriculomegaly is defined as:

Mild, when the atrial measurement is 10 – 12mm.

Mild, when the atrial measurement is 10 – 15mm.

Moderate, when the atrial measurement is greater than 15mm.

Severe, when the atrial measurement is greater than 12mm.

Question Title

* 3. Mothers of fetuses with ventriculomegaly can be counseled as such:

Fetuses with isolated mild ventriculomegaly have no increased risk of abnormal neurodevelopment compared with the healthy population.

Cortical maturation is accelerated in fetuses with ventriculomegaly.

In fetuses with isolated nonsevere ventriculomegaly (INSVM), there are differences in cortical development that are associated with neonatal neurobehavior.

None of the above
