METHODS: Here, the authors observed an asymptomatic case of type 1 GTPVS and two symptomatic cases of type 3 GTPVS, one causing local mass effect and the other hydrocephalus.
CONCLUSIONS: GTPVSs are mostly asymptomatic lesions. Patients without symptoms should be closely monitored, and biopsy is discouraged. Hydrocephalus resulting from GTPVS necessitates surgical intervention. In these cases, third ventriculostomy, shunt implantation, or direct cyst fenestration are surgical options. For patients presenting with symptoms from localized mass effect, a thorough evaluation for potential neurosurgical intervention is imperative. Follow-up in type 3 GTPVS is recommended, particularly in untreated cases. Given the infrequency of GTPVS, definitive guidelines for neurosurgical treatment and subsequent follow-up remain elusive.
方法:这里,作者观察到一个无症状的1型GTPVS病例和两个有症状的3型GTPVS病例,一个引起局部肿块效应,另一个引起脑积水。
结论:GTPVSs大多为无症状性病变。没有症状的患者应密切监测,活检是不鼓励的。由GTPVS引起的脑积水需要手术干预。在这些情况下,第三脑室造瘘术,分流植入,或直接囊肿开窗术是手术选择。对于出现局部肿块效应症状的患者,对潜在的神经外科干预进行全面评估势在必行.建议在3型GTPVS中跟进,特别是在未经治疗的情况下。鉴于GTPVS的频率不高,神经外科治疗和后续随访的最终指南仍然难以捉摸。
