The authors report the case of an infant with a giant glioependymal cyst. Although it has been suggested that these cysts originate from the tela choroidea, their origin remains controversial. This 35-month-old girl with truncal ataxia was referred to the authors' hospital. Magnetic resonance imaging revealed a giant cystic mass extending from the anterior to the posterior cranial fossa. Hydrocephalus was caused by obstruction of the sylvian aqueduct. Endoscopic fenestration of the cyst wall was performed. Histochemical and immunohistochemical staining identified the lesion as a glioependymal cyst. Magnetic resonance imaging performed 8 months later suggested that the cyst originated from the tela choroidea. At 5-year follow-up, there was no tumor recurrence and she had fully recovered. The origin of glioependymal cysts is discussed, and the authors suggest that their origin is the tela choroidea.
作者报告了一例患有巨大胶质室管膜囊肿的婴儿病例。尽管有人认为这些囊肿起源于脉络丛，但它们的起源仍存在争议。这名35个月大患有躯干共济失调的女孩被转诊至作者所在的医院。磁共振成像显示一个巨大的囊性肿块从前颅窝延伸至后颅窝。脑积水是由大脑导水管阻塞引起的。对囊肿壁进行了内镜开窗术。组织化学和免疫组织化学染色确定该病变为胶质室管膜囊肿。8个月后进行的磁共振成像显示囊肿起源于脉络丛。在5年的随访中，没有肿瘤复发，她已完全康复。本文讨论了胶质室管膜囊肿的起源，作者认为其起源为脉络丛。
