Ultrasonographic evaluation of cavum septi pellucidi and cavum Vergae.
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.
