In this paper, we report a case of bilobed schwannoma, presented in the roof of orbit arising from supraorbital nerve. A 62-year male presented with a nontender mass in superior part of orbit and eccentric proptosis. Visual acuity and rest of ocular examination were normal. CT scan and MRI orbit revealed an extraconal homogenous bilobed mass, of size 3.5 to 2.5 cms in roof of orbit. Fine needle aspiration cytology was done, which was suggestive of schwannoma a peripheral nerve tumor. Successful surgical excision of intact bilobed schwannoma was done with careful separation and preservation of supraorbital nerve from which it was originated. Postoperative period was uneventful though rare, less than 1%, schwannoma can present as painless mass in the orbit and proptosis. Treatment of choice is surgical excision of intact tumor to prevent recurrence and preservation of peripheral nerve from which it arises.
在本文中，我们报告了一例双叶状神经鞘瘤，该肿瘤出现在眼眶顶部，起源于眶上神经。一名62岁男性患者，眼眶上部出现无痛性肿块，并伴有眼球偏心性突出。视力及其他眼部检查均正常。眼眶CT扫描和MRI显示眶内有一个3.5至2.5厘米大小的均匀双叶状肿块，位于眼眶顶部。进行了细针穿刺细胞学检查，结果提示为神经鞘瘤，一种周围神经肿瘤。通过小心分离并保留肿瘤起源的眶上神经，成功完整切除了双叶状神经鞘瘤。术后情况平稳，尽管罕见，不到1%的神经鞘瘤可表现为眼眶无痛性肿块和眼球突出。治疗的首选方法是完整切除肿瘤以防止复发，并保留肿瘤起源的周围神经。
