目的总结38例眼眶内神经鞘瘤,分析其临床特点和超声、CT影像学资料。方法收集1975年9月—2006年9月山西省肿瘤医院眼眶内神经鞘瘤住院患者,采用超声及CT检查。结果 38例中,以渐进性眼球突出就诊者23例,眼球突出伴视力下降者6例,眼痛伴眼睑肿胀者1例,发现眶内肿块者8例。22例行超声检查均有异常回声;18例行CT检查均有阳性发现。38例全部行手术治疗,病理结果为神经鞘瘤。结论超声对眶内肿块的定性定位诊断非常重要,能显示肿块的位置、大小、边缘、内部回声及血流情况及与视神经、肌肉的关系,但CT能够显示眶尖部较小肿块,因此,对于眶内肿块均应常规行超声和/或CT检查。 Objective To summarize 38 cases of orbital schwannoma, and to analyze its clinical features and ultrasound, CT imaging data. Methods From September 1975 to September 2006, patients with orbital schwannoma in Shanxi Cancer Hospital were collected and examined by ultrasound and CT. Results Of the 38 cases, 23 cases were treated with progressive eyeballs, 6 cases were with prominent drops of vision, 1 case was accompanied by eye pain and eyelid swelling, and 8 cases were found with orbital mass. Twenty-two cases had abnormal echocardiography and 18 cases had positive CT findings. Thirty-eight patients underwent surgical treatment and the pathological findings were schwannoma. Conclusion Ultrasound is very important for the qualitative diagnosis of orbital tumors. It can show the location, size, edge, internal echo and blood flow of the tumor and the relationship with the optic nerve and muscle. However, CT can show small lumps of the orbital apex, For orbital masses should be routine ultrasound and / or CT examination.
