Age related incidence of cavum septi pellucidi and cavum vergae on CT scans of pediatric patients.

The computed tomography scans of 1,050 infants and children with various degrees of neurological involvement were reviewed to determine the incidence of cavum septi pellucidi (CSP) and cavum Vergae (CV). The incidence was 10% in patients under 1 year, gradually decreasing to 5 to 6% at 2 to 5 years, 2.7% at 6 to 9 years, and 2.3% at 10 to 14 years, with an average rate of 5.5%. An attempt was made to assess possible relationships between clinical syndromes (convulsive disorders, developmental delays, and others) and the presence of CSP-CV. No solid statistical evidence of such relationships could be established.
