摘　　要：目的探讨眼眶原发性异位脑膜瘤的临床表现特征及诊断、治疗方法，以期提高对该病的认识。方法回顾性分析1984～2013年在第三军医大学西南眼科医院诊治的6例眼眶原发性异位脑膜瘤病人的临床、病理资料、治疗方法及随访结果。结果6例患者患眼不伴视力下降，CT结果和手术发现显示5例肿瘤原发于眼眶内上方，1例位于眼眶外后上方，均与视神经无关。术后病理诊断证实6例均为上皮型脑膜瘤。手术方式1例采用常规外侧开眶入路，3例内外侧结合开眶入路，2例采用眶内上缘经皮肤入路完整切除肿瘤。术后随访2个月到9年，2例患者复发。结论原发于眼眶的异位脑膜瘤多位于眼眶内上方，患者的视力通常不受影响，诊断主要依靠病理检查。治疗以手术完整切除为主，肿瘤为良性，预后较好。Objective To investigate the clinical features, diagnosis and treatment of primary in-traorbital ectopic meningioma. Methods Clinical data of six patients with primary intraorbital ecto-pic meningioma from 1984 to 2013 were collected. A morphologic, immunohistochemical analysis was undertaken. Results Computed tomography, magnetic resonance imaging, operative findings and histopathological examination revealed the tumor to be meningothelial meningioma and to be located entirely outside the optic dura. In two patients, tumors located in the anterior inner orbit were surgi-cally removed from the medial orbit. In four patients, the tumors were excised by lateral orbitotomy. The follow-up period varied from two months to nine years. Only two patients recurred. Conclu-sions Primary intraorbital ectopic meningioma mostly locates in the medial orbit. The visual acuity is often normal. The diagnosis of primary intraorbital ectopic meningioma relies on pathologic find-ings. The tumor is benign, the prognosis is fine if the tumor is removed in en bloc.
