Cavum septi pellucidi and cavum vergae are generally asymptomatic fluid collections between the leaves of the septum pellucidum and are present in approximately 15 % of adult brains. These cavities rarely enlarge and become symptomatic causing significant neurological dysfunction as a result of obstruction of the interventricular foramina, distortion of the vascular structures of the deep venous system or compression of the hypothalamoseptal triangle. The authors present a series of four patients with symptoms related directly to pressure effects from the cyst wall to the neighbouring deep brain structures. There were two females and two males with a mean age of 47.5 years. All four patients underwent endoscopic cyst fenestration with a rigid endoscope. In 2 patients frameless neuronavigation was accomplished with the optical tracking system (Radionics, Burlington, USA). All symptoms related to pressure effect resolved after surgery. Endoscopic pellucidotomy of symptomatic cysts of the septum pellucidum produces immediate relief of the mass effect of the cyst and resolution of associated symptoms. Additionally, frameless neuronavigation is a useful tool in planning and realizing the approach and improving intraoperative orientation.
透明隔腔和Vergae腔通常是透明隔叶间无症状的液体积聚，约15%的成人大脑中存在。这些腔隙很少扩大并出现症状，因室间孔阻塞、深静脉系统血管结构扭曲或下丘脑隔三角受压而导致严重神经功能障碍。作者报告了4例症状直接与囊肿壁对邻近深部脑结构的压迫作用相关的患者。其中2例女性，2例男性，平均年龄47.5岁。所有4例患者均使用硬式内镜进行了内镜下囊肿开窗术。2例患者使用光学跟踪系统（美国伯灵顿的Radionics公司）完成了无框架神经导航。术后所有与压迫作用相关的症状均得到缓解。有症状的透明隔囊肿行内镜下透明隔造瘘术可立即缓解囊肿的占位效应并消除相关症状。此外，无框架神经导航是规划和实施手术入路以及改善术中定位的有用工具。
