Cavum septum pellucidum (CSP) and cavum vergae are actually fluid-filled, generally communicating midline cavities located between the third ventricle and corpus callosum. There have been various reports of their association with many behavioral and psychiatric disorders. Infrequently, they have been associated with an obstructive hydrocephalus-like picture. Although the structure and management of CSP has long been known, it has been an enigma as far as functional significance and management indications are concerned. The authors of this article try to analyze the significance of a persistent cavum and involvement of the same entity in varied presentations ranging from an incidental imaging finding to acute hydrocephalus, and propose a possible implication on the present surgical intervention paradigm.
To assess the surgical outcome of fenestration of a CSP cyst.
Retrospective analysis of 3 patients who underwent endoscopic fenestration for CSP with obstructive hydrocephalus between 2012 and 2014 was done, and data were analyzed for symptomatic clinical improvement in particular behavior.
Pre- and postoperative brain MRI showed a significant decrease in the size of the cyst as well as the ventricles. There were no recurrences during follow-up. All of the patients improved.
(1) Endoscopic fenestration of symptomatic CSP cysts is a safe treatment option. (2) Neurocognitive assessment is essential in the evaluation and outcome assessment of CSP.
透明隔腔（CSP）和韦尔加腔实际上是位于第三脑室和胼胝体之间充满液体且通常相互连通的中线腔隙。关于它们与许多行为和精神障碍的关联已有各种报道。它们偶尔与类似梗阻性脑积水的表现相关。尽管CSP的结构和处理方法早已为人所知，但就其功能意义和处理指征而言，一直是个谜。本文作者试图分析持续存在的腔隙的意义以及同一实体在从偶然的影像学发现到急性脑积水等各种表现中的参与情况，并对当前的手术干预模式提出可能的启示。
评估CSP囊肿造瘘术的手术效果。
对2012年至2014年间因梗阻性脑积水接受CSP内镜造瘘术的3例患者进行回顾性分析，并对特定行为的症状性临床改善情况进行数据分析。
术前和术后脑部MRI显示囊肿以及脑室大小显著减小。随访期间无复发。所有患者均有改善。
（1）有症状的CSP囊肿内镜造瘘术是一种安全的治疗选择。（2）神经认知评估在CSP的评估和结果评估中至关重要。
