Case report

A 41-year-old G2 P0 was referred to our department at 15 weeks for an amniocentesis due to her advanced maternal age. She had a history of early pregnancy miscarriage. Her personal and family history were both negative.

The ultrasound scan at 15 weeks did not show any abnormalities. The amniocentesis had a normal karyotype result.
The subsequent ultrasound scan at 19 weeks of gestation showed bilateral dilation of the lateral ventricles (12-13 mm).

Patient was counselled by geneticist who suggested a TORCH panel. The results confirmed a cytomegalovirus infection. Patient decided for the pregnancy termination.
