Case report

A 27-year-old woman (G1P0) with non-contributive history was sent to our office at 31 weeks gestational age. Her previous examinations were reported to be normal.

Our examination revealed dilated lateral cerebral ventricles, absent cavum septum pellucidum, agenesis of the corpus callosum, aberrant course of the pericallosal artery, falx cerebri reaching the roof of the slightly dilated third cerebral ventricle, disproportion of the cardiac ventricles with dominant right ventricle and smaller left ventricle with pericardial effusion (a more precise investigation of the heart was not possible due to inconvenient position of the fetal thorax). Intrauterine growth restriction was also noted - biometry of the femurs and humeri corresponded just to 27 weeks, fetal abdomen corresponded to 29 weeks + 3 days, but biometry of the head was slightly increased, and corresponded to 30 (OFD) and 32 (BPD) weeks of gestation.

The female newborn was delivered at term and died three weeks later due to cardiac failure. Postnatal examination confirmed the findings, and consequent karyotyping revealed Turner syndrome (45X0).

We do not have pathological report to our disposal to confirm that, but the disproportion of the cardiac ventricle could be a cause of aortic coarctation which is often seen in cases of the Turner syndrome.

Images 1, 2: 31 weeks gestational age; images show transverse scans of the fetal head with striking dilatation of the lateral ventricles (the width of the lateral ventricle is measured on the image 2 - 25.2 mm).
