A 14 month old boy with sudden onset of proptosis of the left eye due to an aneurysmal bone cyst of the orbit is reported. Sequential plain films of the orbital region demonstrated changes ranging from subtle loss of bone definition of the orbital margin to the characteristic appearance of an aneurysmal bone cyst twelve months later. Arteriography at the time of the initial evaluation demonstrated prolonged retention of the contrast medium which we believe represents changes secondary to the number of giant cells present in the tumor rather than the relative vascularity of the lesion. While aneurysmal bone cyst of the orbit is extremely rare, it should be included in the differential diagnosis of proptosis in the pediatric age group.
报告了一名14个月大的男孩，因眼眶动脉瘤样骨囊肿导致左眼突然眼球突出。眼眶区域的系列平片显示出一系列变化，从眼眶边缘骨轮廓的细微丧失到12个月后动脉瘤样骨囊肿的特征性表现。初始评估时的动脉造影显示造影剂滞留时间延长，我们认为这代表了肿瘤中巨细胞数量导致的继发性改变，而非病变的相对血管化程度。虽然眼眶动脉瘤样骨囊肿极为罕见，但在小儿年龄组眼球突出的鉴别诊断中应考虑到该病。
