Cranial sonography in extremely preterm infants

Area of Science:

• Neonatal neurology
• Pediatric radiology
• Neuroimaging

Background:

• Dramatic improvements in neonatal care have increased survival rates for extremely preterm infants.
• Cranial sonography is crucial for diagnosing brain injuries in these vulnerable infants.
• Unique maturational features in extremely preterm infants require specialized interpretation of sonographic findings.

Purpose of the Study:

• To provide a comprehensive pictorial guide to cranial sonography in extremely preterm infants.
• To illustrate normal anatomy and common variants.
• To highlight potential pitfalls that can lead to misdiagnosis.

Main Methods:

• Review of cranial sonographic images from a cohort of extremely preterm infants.
• Correlation of sonographic findings with clinical data and neurodevelopmental outcomes.
• Emphasis on age-related anatomical changes and common pathologies.

Main Results:

• Detailed visualization of normal brain structures and their evolution in preterm infants.
• Identification of common variants that may mimic pathology.
• Examples of frequent misinterpretations and their causes.

Conclusions:

• Accurate interpretation of cranial sonography in extremely preterm infants requires understanding their unique neurodevelopmental anatomy.
• Familiarity with normal variants and potential pitfalls is essential for early and correct diagnosis.
• This pictorial essay serves as a valuable resource for clinicians interpreting neonatal brain imaging.
