Paraventricular fluid cysts have recently been treated by endoscopic fenestration performed from the cysts to the ventricular system. However, correct orientation and safe navigation of the endoscope may be difficult in patients with abnormal anatomy. Endoscopic fenestration from the ventricular system to a cyst was performed through penetration of the septum pellucidum via the anterior horn of the contralateral lateral ventricle. The advantage of this approach is correct orientation and introduction of the endoscope to the periventricular lesion because the usual landmarks can be identified in the normal contralateral lateral ventricle.
室周脑脊液囊肿最近通过从囊肿到脑室系统进行的内镜开窗术进行治疗。然而，对于解剖结构异常的患者，内镜的正确定位和安全导航可能会很困难。通过对侧侧脑室前角穿透透明隔，从脑室系统到囊肿进行内镜开窗术。这种方法的优点是内镜能够正确定位并进入脑室周围病变，因为在正常的对侧侧脑室中可以识别出常见的标志。
