This 46-year-old female patient presented after a 6-month progressive right-sided visual loss, with a visual acuity of 20/60, a temporo/infranasal visual field deficit, and optic atrophy. The magnetic resonance imaging disclosed a tuberculum sella meningioma with minimal right medial canal invasion, however, no encasement of carotid arteries. Tuberculum sella meningiomas represent 5%-10% of intracranial meningiomas and are surgically challenging tumors that can severely hinder vision. The endoscopic approach allows for early coagulation of the tumor meningeal supply, and importantly, facilitates gross total removal without any manipulation of the optic nerve while preserving the superior hypophyseal arteries..
这位 46 岁女性患者因右侧视力渐进性丧失 6 个月就诊，视力为 20/60，表现为颞下/鼻侧视野缺损和视神经萎缩。磁共振成像显示鞍结节脑膜瘤，仅轻微累及右侧内侧眶上裂，但颈动脉不受累。鞍结节脑膜瘤占颅内脑膜瘤的 5%-10%，是手术极具挑战性的肿瘤，可严重妨碍视力。神经内镜可早期对肿瘤脑膜供血进行凝固，重要的是，在不损伤视神经的情况下实现大体全切除，同时保留垂体上动脉。
