Background: The reported prevalence of cavum septum pellucidum (CSP) and cavum vergae (CV) on computed tomography (CT) was 5.5% in Great Britain and 1.24% in China but has been virtually unknown in the aged Taiwanese population. In the study, we aimed at building related data from the patients of our hospital.Methods: From July 2008 to August 2010, a total of 1,228 patients had received brain CT at a local hospital in northern Taiwan. The films were reviewed to check for CSP and CV.Results: There were 13 patients (9 males and 4 females) with CSP or CV. Their age was 73.5±8.5 (average±SD) years, with a range from 65 to 94 years old. Among them, none had only CSP, 23.1 % (n=3) had only CV, and 76.9 % (n=10) had coexistent CSP and CV. The average inner width of CSP was 7.3±1.7 mm (n=10), and that of CV was 7.3±3.1 mm (n=13).Conclusions: This is the first study of CSP and CV in the aged Taiwanese population. The prevalence of CSP or CV in all brain CT is estimated to be 1.06%, which is not rare.
