Abstract:
Choroid plexus papilloma (CPP) is a rare benign intracranial tumor origin that predominantly manifests in the lateral ventricle in children, accounting for 0.3%-0.6% of all primary intracranial tumors. It is extremely rare to have the CPP in the trigone of the lateral ventricle through the contralateral posterior interhemispheric transfalcine transprecuneus approach (PITTA). Herein, we report this rare case. A 7-year-old girl presented with headache. Magnetic resonance imaging of the brain showed periatrial lesions, and histopathological examination confirmed CPP (WHO grade I). The contralateral PITTA is a safe, effective, reasonable, and appropriate for some lesions in the trigone of the lateral ventricle. It provides a wider surgical angle (especially for the lateral extension) and reduces the risk of disturbance of the optic radiation compared with the conventional approaches. The use of multiple modern neurosurgical techniques, including interventional embolization, intraoperative navigation, microscope, and electrophysiological monitoring, make the procedure much easier and more accurate, and the neuroendoscope adds to the visualization of the microscope and can reduce surgical complications.
摘要:
脉络丛乳头状瘤(CPP)是一种罕见的良性颅内肿瘤,主要表现在儿童的侧脑室。占所有原发性颅内肿瘤的0.3%-0.6%。通过对侧后半球间横裂肌入路(PITTA)在侧脑室三角区的CPP极为罕见。在这里,我们报告了这个罕见的病例。一个7岁的女孩出现头痛。脑部磁共振成像显示心房周围病变,组织病理学检查证实CPP(WHOI级)。对侧PITTA是安全的,有效,合理,适用于侧脑室三角区的某些病变。与常规方法相比,它提供了更宽的手术角度(特别是对于横向延伸)并且降低了光学辐射的干扰风险。使用多种现代神经外科技术,包括介入栓塞,术中导航,显微镜,和电生理监测,使程序更容易,更准确,神经内窥镜增加了显微镜的可视化,可以减少手术并发症。
