Prenatal ultrasonography and neonatal imaging of complete cleft sternum: a case report

The prenatal diagnosis of a complete cleft sternum was established in a fetus of a twin pregnancy at 22 weeks' gestation. We present the prenatal imaging and correlation with postnatal magnetic resonance imaging and high-resolution ultrasonography. Thinned and depressed midline anterior chest wall transmitting the cardiac pulsation was the clue to the diagnosis, and the defective sternum could be identified on close sonographic observation. Successful surgical correction was undertaken at 2 months of age. There were no major associated abnormalities such as ectopia cordis or midline abdominal wall defects.
