The case of a 36-year-old healthy, asymptomatic man who was monitored for a slowly growing subcutaneous mass under his right inferior orbital rim for more than ten years is presented. The mass was hard, immobile, and nontender. Computed tomography (CT) documented a lytic lesion at the frontal process of the right maxilla. Four years later, magnetic resonance imaging (MRI) of the orbits revealed distinct lesions in the right zygoma, maxillary, and greater wing of the sphenoid bones. These lesions were hypointense with respect to orbital fat on T1-weighted images and hyperintense on T2-weighted series. There was moderate enhancement after contrast agent administration. These findings combined with the clinical features of the patient were suggestive of presumed multiple orbital intraosseous hemangiomas. Differential diagnosis between other osseous tumors of the orbit can be reasonably made based on imaging characteristics.
本文报告了一例36岁健康无症状男性的病例，该患者右下眼眶缘下有一个缓慢生长的皮下肿块，已被监测了十多年。肿块质地坚硬，固定不动，无压痛。计算机断层扫描（CT）显示右上颌骨额突有一个溶骨性病变。四年后，眼眶磁共振成像（MRI）显示右侧颧骨、上颌骨和蝶骨大翼有明显病变。这些病变在T1加权图像上相对于眼眶脂肪呈低信号，在T2加权序列上呈高信号。注射造影剂后有中度强化。这些发现结合患者的临床特征提示可能为多发性眼眶骨内血管瘤。根据影像学特征可以合理地对眼眶其他骨肿瘤进行鉴别诊断。
