    This study measured brain ventricle width in premature infants. While the third ventricle appeared normal, the brain mantle index yielded unreliable results, possibly due to technical challenges.

    Area of Science:

    • Neonatal Neurology
    • Pediatric Imaging
    • Neurodevelopmental Pediatrics

    Context:

    • Premature infants (birth weight < 2500g) pose unique challenges in neurodevelopmental assessment.
    • Early neuroimaging is crucial for identifying potential neurological complications in this vulnerable population.
    • Standardized measurement techniques are essential for reliable interpretation of pediatric neuroimaging.

    Purpose:

    • To evaluate the width of the third ventricle and the brain mantle index in premature infants post-weight gain.
    • To assess the correlation between these measurements and birth weight or gestational age.
    • To identify potential technical limitations in echoencephalography for neonatal brain assessment.

    Summary:

    • A cohort of 125 premature infants underwent echoencephalography upon reaching 2500g birth weight.

  • The third ventricle width was consistently normal (2-3 mm), independent of birth weight and gestational age, with only two infants showing elevated values.
  • The brain mantle index produced highly variable and unsatisfactory results (2.35-4.91), significantly exceeding normal adult values, suggesting methodological issues.

    • Impact:

    • Establishes normative data for third ventricle width in a specific premature infant cohort.
    • Highlights significant technical challenges and inaccuracies in calculating the brain mantle index using echoencephalography in neonates.
    • Suggests a need for refinement of imaging techniques or alternative methods for assessing brain mantle development in premature infants.
