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.
The PC is thought to have developed in association with TVS stoma closure and resolved after ETV revision.
一名 13 岁女性患者被诊断为顶盖胶质瘤（TG），这是一种星形细胞瘤亚组，可导致导水管狭窄继发梗阻性脑积水。神经内镜第三脑室造瘘术（ETV）用于治疗此类脑积水，成功率较高。我院对这类病例施行 ETV 和 Ommaya 储液囊（OR）植入术。OR 可以测量颅内压（ICP）和获取脑脊液（CSF），还可以进行脑室染料研究以评估第三脑室造瘘口（TVS）通畅性。本例患者在术后 2 个半月时，OR 的脑室导管（OVC）周围出现了一个脑穿通性囊肿（PC）。
PC 可能与 TVS 造瘘口关闭有关，在 ETV 修正术后得到缓解。
