目的 探讨眼眶占位性病变导致骨质改变的CT特点及临床意义.方法 回顾阅读天津眼科医院2007年4月至2009年9月期间眼眶占位性病变住院病例CT片213例,分析其骨质改变的特点,总结归纳骨质改变在临床诊断和治疗中的价值.结果 213例眼眶占位病例中有97例发生骨质改变,其中血管性疾病,囊肿性疾病最多见.骨质改变类型大致可分为骨缺损（82例）,骨增生（10例）,眶上下裂扩大（8例）和眶腔扩大（20例）四大类,既可单独存在也可互相并存.骨质缺损又可以分为良性压迫吸收,恶性侵袭改变,先天发育异常及炎症刺激四类.骨质增生可以分为良性异常增生,肿瘤性增生和反应性增生.眼眶四壁骨缺损以外、上、内壁最多见,眶下壁受累最少.结论 眼眶内不同占位疾病的CT骨质改变特点不同,临床处理也不同.应用CT显示分析骨质改变的特点,对临床诊断及治疗具有指导意义.
Objective To discuss the CT manifestations and the significance for clinical diagnosis of orbital bony changes caused by orbital mass. Methods All 213 inpatients＇s CT scans of orbital masses from 2007 Aprto 2009 Sep in Tianjin Eye Hospital were reviewed. The feature of bony changes in CT and the value of bony changes in clinical diagnosis and treatment were analyzed and summarized. Results Of the 213 CT scans, 97 had bony changes. Most were vascular lesions and cysts. There were four types of bony changes in orbital masses： bone coloboma （82 cases）, bone proliferation （10 cases）, orbital cavity enlarging （20 cases）, superior orbital fissure and inferior orbital fissure enlarging （8 cases）, which occured alone or side by side. Bone coloboma could be caused by four reasons： benign compression, malignant erosion, heteroplasia and inflammation. Bone proliferation was sorted into benign dysplasia, malignance and reactivity. Bone coloboma most occurred in the roof, lateral wall, medial wall of orbit, orbital floor was rare. Conclusions Different orbital masses have different features of bony changes in CT scans and receive different treatments. Analyzing the features of bony changes in CT scans has a great significance in clinical diagnosis and treatment of orbit masses.
