A case of retro-orbital meningioma who presented to the Department of Surgery, Neuro-surgery Unit of Tikur Anbessa Hospital in June 1993 with a progressive right eye proptosis is described. Exploration through a right frontal craniotomy showed a well circumscribed and encapsulated thickened bony tumor that had a cavity containing a cheesy-yellowish oily material. The lesion was successfully shelled-out. The preoperative diagnosis was meningioma. However, based on its intraoperative macroscopic appearance, mode of presentation, and location of the lesion an impression of an epidermoid tumor (cholesteatoma) was made. The result of histologic examination turned out to be meningioma (psammomatous type). Literature review on both conditions, the pathologic characteristics and clinical features are discussed briefly.
本文描述了一例眶后脑膜瘤患者，该患者于1993年6月因右眼进行性突出就诊于提库尔·安贝萨医院神经外科手术部。经右额开颅探查发现一个边界清楚、有包膜的增厚骨性肿瘤，肿瘤腔内含有干酪样黄色油性物质。该病变被成功完整切除。术前诊断为脑膜瘤。然而，根据其术中宏观表现、临床表现及病变位置，考虑为表皮样肿瘤（胆脂瘤）。组织学检查结果为脑膜瘤（砂粒体型）。本文简要讨论了这两种疾病的文献综述、病理特征及临床特点。
