Schwannoma is a rare benign tumor, originating from Schwann cells of the peripheral nerve sheath. We describe a case of intraconal orbital schwannoma, causing compression to the optic nerve and progressive visual impairment treated with surgical resection. The diagnosis of benign orbital schwannoma was provided by histopathological examination (large spindle cell tumor with AntoniB-type cell pattern) and also with immunohistochemistry (positivity for S-100 protein). The 6 months' follow-up was performed. The patient was asymptomatic during the 6-month follow-up.
神经鞘瘤是一种罕见的良性肿瘤，起源于周围神经鞘的施万细胞。我们描述了一例发生在眶内的神经鞘瘤，由于视神经受压导致进行性视力损害，经手术切除治疗。良性眶内神经鞘瘤的诊断依据是组织病理学检查（大梭形细胞肿瘤，具有 AntoniB 型细胞模式）和免疫组织化学检查（S-100 蛋白阳性）。进行了 6 个月的随访。在 6 个月的随访期间，患者无症状。
