Encephalocele is defined as a protrusion of cranial contents beyond the normal confines of the skull. Encephaloceles occur with an incidence of approximately 1 in 3,000-10,000 births and are categorized based on location in the skull. Orbital meningoencephalocele is a rare congenital abnormality caused by a defect of the cranio-orbital bones that usually manifests soon after birth as a soft mass associated with exophthalmos. We present a case of a giant orbital meningocele presenting as an orbital mass in a 15 months-old girl. Preoperative diagnosis was confirmed by CT-scan and magnetic resonance imaging.
脑膨出被定义为颅内容物突出于颅骨正常边界之外。脑膨出的发生率约为每3000 - 10000例出生中有1例，并根据其在颅骨中的位置进行分类。眶内脑膜脑膨出是一种罕见的先天性异常，由颅眶骨缺损引起，通常在出生后不久表现为与眼球突出相关的柔软肿块。我们报告一例15个月大女孩的巨大眶内脑膜脑膨出，表现为眶内肿块。术前诊断通过CT扫描和磁共振成像得以证实。
