Abstract

Objective: The reported prevalence of cavum septum pellucidum (CSP) and cavum Vergae (CV) in brain computed tomography (CT) is 5.5% in Great Britain and 1.24% in China but unknown in Taiwan. Moreover, CSP and/or CV has generally been thought to decrease as age progresses, but the evidence of actual prevalence at different age levels is still limited in the literature. Methods: A total of 19,031 patients with brain CT at a regional hospital in northern Taiwan from July 2008 to August 2010 were included in this study. Their radiological official reports were retrospectively reviewed to check for CSP and/or CV. An X2 test was used for statistical analysis (α=.05). Results: The prevalence of CSP and/or CV in all brain CT was 0.93% (n = 177), which was lower than that in the Chinese and British studies. Among them, 2.8% (n = 5) had only CSP, 1.7% (n = 3) had only CV, and 95.5% (n = 169) had coexistent CSP and CV. There is a significant difference in prevalence between the age groups (p = .009), and the prevalence is the highest in the group aged 20-29 years (1.56%) and lowest in the group aged above 80. After age 20-29, the prevalence tends to decrease with increasing age. Conclusion: This is not only the first study of CSP and CV in the Taiwanese population but the study population is also larger than those in the literature. The prevalence was found to approximately decrease as age progresses, but would reach the peak in the young adult group rather than the children or adolescent group.
