Antenatal three-dimensional sonographic features of early amnion rupture sequence

Area of Science:

• Medical Imaging
• Prenatal Diagnosis
• Fetal Medicine

Background:

• Early amnion rupture sequence is a rare congenital condition.
• Antenatal diagnosis of this condition is challenging.
• Limited information exists on the three-dimensional sonographic features of early amnion rupture sequence.

Purpose of the Study:

• To report the antenatal three-dimensional sonographic features of early amnion rupture sequence.
• To highlight the utility of 3D sonography in diagnosing complex fetal anomalies.

Main Methods:

• A case study of a 24-year-old pregnant woman at 16 weeks of gestation.
• Utilized three-dimensional sonography to visualize fetal anatomy.
• Delivery was induced at 17 weeks of gestation, followed by autopsy.

Main Results:

• Three-dimensional sonography clearly depicted multiple fetal anomalies including scalp adhesion, skull defect, abdominal wall disruption, limb amputation, kyphoscoliosis, and clubfeet.
• Autopsy confirmed the prenatal diagnosis of early amnion rupture sequence.
• The fetus weighed 166 grams at 17 weeks of gestation.

Conclusions:

• Three-dimensional sonography offers enhanced visualization of fetal anatomy.
• It aids in the unique identification of specific anatomic planes.
• Provides realistic and reliable depiction of complex fetal anomalies, improving prenatal diagnosis.
