A case of an anterior third ventricular meningioma in a 17-year-old girl is presented. Gross total resection of this tumor with minimal morbidity was accomplished by transcallosal exposure through a frontal craniotomy. A review of the literature implies that surgical morbidity and mortality for the removal of third ventricular meningiomas markedly improved with the use of the operating microscope. Despite advanced imaging capabilities, radiographic analysis of a solid third ventricular mass may not always determine tissue diagnosis. In addition, preoperative placement of a ventriculoperitoneal shunt will treat hydrocephalus, but may limit the surgical options for tumor exposure. The differential diagnosis for this solid anterior third ventricular mass is presented, and the method of treatment for this case is discussed.
本文报道了一名17岁女孩的前第三脑室脑膜瘤病例。通过额部开颅经胼胝体入路，实现了该肿瘤的大体全切，且手术并发症极少。文献回顾表明，使用手术显微镜可显著改善第三脑室脑膜瘤切除的手术并发症和死亡率。尽管有先进的影像学检查能力，但对实性第三脑室肿块的影像学分析可能并不总能确定组织诊断。此外，术前放置脑室腹腔分流管可治疗脑积水，但可能会限制肿瘤暴露的手术选择。本文介绍了该实性前第三脑室肿块的鉴别诊断，并讨论了该病例的治疗方法。
