Background

A 13-year-old female patient was diagnosed with a tectal glioma (TG), a subgroup of astrocytoma that can result in obstructive hydrocephalus secondary to aqueductal stenosis. Endoscopic third ventriculostomy (ETV) is used to treat this type of hydrocephalus with a good success rate. Our institution performs ETV and Ommaya reservoir (OR) placement in these cases. The OR allows measurement of intracranial pressure (ICP) and cerebrospinal fluid (CSF) access and a method for performing ventricular dye studies to evaluate third ventricular stoma (TVS) patency. In this case, a porencephalic cyst (PC) developed around the OR’s ventricular catheter (OVC) two and a half months after surgery.

Conclusion

The PC is thought to have developed in association with TVS stoma closure and resolved after ETV revision.

内镜下第三脑室造口术和 Ommaya 水库放置后的脑穿孔囊肿：病例报告和文献复习

背景

一名 13 岁女性患者被诊断患有顶盖神经胶质瘤 (TG)，这是一种星形细胞瘤亚组，可导致继发于导水管狭窄的阻塞性脑积水。内窥镜第三脑室造口术 (ETV) 用于治疗这种类型的脑积水，成功率很高。我们机构在这些情况下执行 ETV 和 Ommaya 水库 (OR) 放置。OR 允许测量颅内压 (ICP) 和脑脊液 (CSF) 通路以及执行心室染料研究以评估第三脑室造口 (TVS) 通畅性的方法。在这种情况下，手术后两个半月，OR 的脑室导管 (OVC) 周围出现了穿孔脑囊肿 (PC)。

结论

PC 被认为与 TVS 造口闭合有关，并在 ETV 修订后解决。
