Abstract：
Meningiomas are benign tumors of the central nervous system (CNS) that usually result in compression to adjacent structures and rarely cause pathology on their own. Meningiomas can affect the visual pathways originating from perineural or optic nerve sheath meningioma (ONSM), sellar, or clinoid, to the frontal-temporal-parietal-occipital lobes. Frontal meningiomas have an indolent presentation with frequent behavioral changes (i.e., personality or emotional changes, visual hallucinations), but they rarely present with visual disturbances. We present a case of a giant frontal meningioma causing progressive visual field loss despite preserved visual acuity and no behavioral changes. We aim to highlight the diagnostic value of performing a detailed ophthalmologic evaluation with confrontation visual field (CVF) testing and interpretation in aiding the discovery and diagnosis of intracranial tumors.
摘要：
脑膜瘤是中枢神经系统(CNS)的良性肿瘤,其通常导致对邻近结构的压迫,并且很少自身引起病理学。脑膜瘤可影响源自神经周或视神经鞘脑膜瘤（ONSM）的视觉通路，塞拉，或者斜骨，额叶-颞叶-顶叶-枕叶。额叶脑膜瘤表现缓慢，行为频繁变化(即，个性或情感的变化，视觉幻觉)，但他们很少出现视觉障碍。我们介绍了一例巨大的额叶脑膜瘤，尽管视力保持且没有行为改变，但仍导致进行性视野丧失。我们旨在强调通过对抗视野（CVF）测试和解释进行详细的眼科评估的诊断价值，以帮助发现和诊断颅内肿瘤。
