title: Ultrasonographic evaluation of cavum septi pellucidi and cavum Vergae.
abstract: Cavum septi pellucidi (CSP) and cavum Vergae (CV) are frequently found in premature and mature neonates an autopsy. We examined 116 premature infants, 45 full-term neonates and 31 healthy 1-month-old infants to clarify the incidence of CSP and CV using cranial ultrasonography through anterior fontanelle. CSP was detected in 97% of the premature infants, 56% of the full-term neonates and 29% of the 1-month-old infants. The incidence of CV was 60% in premature infants and 7% in full-term neonates. None of the 1-month-old infants were found to have CV. The size of the largest CSP observed ultrasonographically was 10 mm wide. No complicated pathological cavum was found in any subject.
