摘要

目的：從英國研究得知，在電腦斷層掃描中發現透明間隔腔或邊緣腔的盛行率為5.5%，中國研究為1.24%，但在臺灣老年人（65歲以上）則未知。本文設法從本院病患中得到數據。方法：回顧北臺灣某地區醫院，從2008年7月至2010年8月間，共計1,228名老年患者在該院接受過腦部電腦斷層掃描，從中尋找透明間隔腔與邊緣腔。結果：共13名（9男與4女）患者之電腦斷層掃描發現透明間隔腔或邊緣腔，年齡為73.5±8.5（平均值±標準差），其中無人僅具透明間隔腔，23.1%(n=3)僅具邊緣腔，而76.9%(n=10)則兩者兼具。所有透明間隔腔之內寬為7.3±1.7mm(n=10)，而邊緣腔之內寬為7.3±3.1mm(n=13)。結論：這是第一篇以台灣老年族群為對象，研究透明間隔腔與邊緣腔之報告。在所有腦部電腦斷層掃描中發現的盛行率為1.06%，其實並不少見。

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.
