摘要
透明隔囊肿分为症状性与非症状性两种,前者又称为扩张性透明隔囊肿,它可造成室间孔的梗阻,产生头痛、呕吐、视乳头水肿及意识障碍等颅压增高症状。当透明隔囊肿累及下丘脑一隔三角区或影响脑深部的静脉回流时,可出现行为、自主神经以及感觉运动功能的异常。一旦发生脑积水,可压迫视神经通路,引起神经眼科方面的症状。根据MRI所见和临床表现特点可确定诊断。应用脑的内窥镜技术,施行透明隔囊肿-脑室造屡或分流手术,可解除梗阻性脑积水,迅速缓解临床症状。
Cysts of the septum pellucidum consist of symptomatic and asymptomatic types. The former cysts, also named expending cysts of the septum pellucidum, become symptomatic as a result of obstruction of the interventricular foramina, producing headache, papilledema, vomit and disturbance of consciousness. Behavioral, autonomic and sensorimotor symptoms occur when an expending cyst impinges on the structures of the hypothalamoseptal triangle or impairs the deep cerebral venous drainage. Neuroophthalmological symptoms may develop as a consequence of hydrocephalus or direct compression of visual structures. Diagnosis of cysts of septum pellucidum can be made by means of MRI and clinical manifestations. Fenestration or shunting with neuroendoscopic technique will relieve the obstructive hydrocephalus and produce rapid symptomatic improvement.
