ABSTRACT
Elevation of blood sugar level during pregnancy is linked to suboptimal perinatal outcomes, including miscarriage, fetal malformations, stillbirth, and birth asphyxia. Diabetes mellitus is considered a major risk factor for abnormal fetal development. Diabetes mellitus is one of the most common medical disorders during pregnancy, affecting approximately 3%–10% of women. Due to the higher chance of fetal malformations, detailed routine fetal ultrasound examination is offered in pregnant women with diabetes mellitus, especially for those with poor glycemic control in the first trimester. Ultrasound and magnetic resonance imaging (MRI) are considered as complementing imaging technologies. Ultrasound has been the principal imaging modality in fetal medicine. MRI is an alternative imaging method that can confirm or complement abnormal ultrasound findings. Fetal caudal regression syndrome is usually detected by screening ultrasound examination. It has a typical sonographic finding of a sudden interruption of the spine with absent or hypoplastic sacrum.
