目的：单独发现透明隔腔(CSP)的意义及其在健康人和职业拳击手中的患病率存在争议。很少有磁共振成像(MRI)研究关注大量的拳击手。本研究的目的是确定职业拳击手中CSP的患病率和程度，并将其与对照组进行比较。方法：回顾164名接受年度英国拳击板执照续签扫描的男性拳击手的MRI检查，并与43名对照组进行比较。记录CSP的患病率、大小和范围。范围分为类型1，穹隆前；类型2，延伸至穹隆；类型3，延伸至穹隆。结果：40%的对照组和49%的拳击手存在CSP。拳击手CSP患病率有升高趋势(P=0.099)。没有对照组患者有2型或3型伸展(P<；.0009)，而拳击手的患病率分别为30%和16%。三名拳击手在连续成像的基础上增加了他们的范围。两组间CSP大小并无差异(P=.43)，但在拳击手中，进行性扫描与CSP大小随时间增加之间存在关联，与年龄无关(P=.05)。8名拳击手在随后的扫描中显示了早期扫描中未见的CSP。结论：CSP在对照组患者和拳击手中的患病率都很高。有一种更大的CSP的趋势，扫描的次数越来越多，没有萎缩的证据，而且与年龄无关。拳击手也比对照组有更大的后部范围。这些发现可能是由于颅内压突然升高，迫使脑脊液(CSF)通过隔叶上的小缺陷，导致CSP的大小和/或范围增加。
Objective: Controversy exists over the significance of the isolated finding of cavum septi pellucidi (CSP) and its prevalence rate in healthy individuals and in professional boxers. Few magnetic resonance imaging (MRI) studies have looked at large cohorts of boxers. The aim of this study was to identify the prevalence and extent of a CSP among professional boxers and to compare these with a control group.Methods: MRI studies of 164 male boxers scanned for annual British boxing board license renewal were reviewed and compared with 43 control patients. CSP prevalence, size, and extent were recorded. Extent was classified as type 1, anterior to the fornix; type 2, extending up to the fornix; and type 3, extending into the cavum vergae. Parenchymal abnormalities were documented, and the Evan's ratio was used as an indication of brain atrophy.Results: A CSP was present in 40% of controls and 49% of boxers. There was a trend to a higher CSP prevalence in boxers (P = .099). No control patient had type 2 or 3 extension (P < .0009), as opposed to 30% and 16% prevalence in boxers. Three boxers increased their extent over serial imaging. No difference in CSP size was established between the 2 groups (P= .43), but there was an association between progressive scans and increased CSP size over time in boxers, independent of age (P = .05). Eight boxers demonstrated a CSP on a subsequent scan not seen on an earlier scan.Conclusion: The prevalence of a CSP is high among both control patients and boxers. There is a trend to a larger CSP with increasing number of scans without evidence of atrophy and independent of age. Boxers also have a greater posterior extent than controls. The findings may be explained by sudden increases in intracranial pressure that forced cerebrospinal fluid (CSF) through small defects in the septal leaflets, which result in an increase in size and or extent of a CSP.
