Cavum septi pellucidi (CSP) are benign developmental cystic midline cavities that are located between the lateral ventricles through the foramina of Monro. CSP are usually asymptomatic and have no cerebrospinal fluid (CSF) flow. Although their incidence is increased in association with head trauma, as well as psychiatric and behavioural disorders, this increase seldom causes disease. Herein, we discuss the case of a toddler who presented with episodic headaches for 6 weeks with associated vomiting triggered by strenuous activity. His neurological examination was normal. His MRI brain scan revealed large cavum septum pellucidum with obstructive hydrocephalus. He underwent endoscopic fenestration of the cyst with resolution of both hydrocephalus and the symptoms. Although CSP are generally asymptomatic, in rare situations, as in our illustrative case, they may cause obstructive hydrocephalus that requires urgent attention. CSF flow studies are helpful in confirming the diagnosis.
透明隔腔（CSP）是位于侧脑室之间、通过孟氏孔的良性发育性囊性中线腔隙。CSP通常无症状，且无脑脊液（CSF）流动。尽管其发生率在与头部外伤以及精神和行为障碍相关时会增加，但这种增加很少导致疾病。在此，我们讨论一例幼儿病例，该患儿出现发作性头痛6周，伴有剧烈活动引发的呕吐。其神经系统检查正常。他的脑部MRI扫描显示有巨大透明隔腔并伴有梗阻性脑积水。他接受了囊肿内镜开窗术，脑积水和症状均得到缓解。尽管CSP通常无症状，但在罕见情况下，如我们的病例所示，它们可能导致需要紧急关注的梗阻性脑积水。脑脊液流动研究有助于确诊。
