In utero diagnosis of caudal regression syndrome

Area of Science:

• Developmental biology
• Neurology
• Medical imaging

Background:

• Caudal regression syndrome (CRS) is a rare congenital anomaly affecting the lower spine and extremities.
• CRS is strongly associated with pregestational diabetes mellitus, with a significantly higher prevalence in infants of diabetic mothers.
• Understanding the etiology and presentation of CRS is crucial for prenatal diagnosis and management.

Observation:

• This report details a case of prenatally suspected CRS in a fetus born to a mother without pregestational diabetes.
• Initial neuroimaging revealed specific abnormalities in the fetal spine and neurological structures.
• The study focuses on the correlation between these prenatal findings and the infant's clinical presentation after birth.

Findings:

• The case demonstrates that CRS can occur in the absence of maternal diabetes, challenging typical etiological assumptions.
• Prenatal neurological imaging findings were found to correlate with the observed clinical deficits in the infant.
• This case expands the known spectrum of CRS presentation and potential contributing factors.

Implications:

• This case underscores the importance of considering CRS even in non-diabetic pregnancies.
• Accurate prenatal imaging and neurological assessment are vital for predicting postnatal outcomes in suspected CRS cases.
• Further research into the diverse etiologies of CRS may improve early detection and intervention strategies.
