Several months after a fall down a flight of stairs, a one-year-old girl developed downward displacement and pulsation of the left eye. Vision and ocular motility were not impaired and the child remained neurologically normal. Computed tomography with metrizamide cisternography demonstrated herniation of brain tissue through a traumatic defect in the roof of the orbit. The orbital rim and other craniofacial bones were intact. Repair of the growing fracture found at operation restored normal appearance without disturbing function. To our knowledge, this is the first documented case of encephalocele associated with an isolated fracture of the orbital roof due to blunt head trauma.
一名一岁女童从一段楼梯上摔下几个月后，左眼出现向下移位和搏动。视力和眼球运动未受损害，孩子的神经系统仍保持正常。计算机断层扫描及甲泛葡胺脑池造影显示脑组织通过眼眶顶部的外伤性缺损疝出。眶缘和其他颅面骨完整。手术中发现的生长性骨折修复后恢复了正常外观，且未影响功能。据我们所知，这是第一例有文献记载的因钝性头部外伤导致孤立性眶顶骨折伴脑膨出的病例。
