眼眶肿瘤的影像学诊断分析

目的：探讨眼眶肿瘤的影像学诊断特点。方法：对我院经手术病理证实的资料完整的眼眶肿瘤37例,其中血管瘤10例,皮样囊肿8例,炎性假瘤5例,脉络膜恶性黑色素瘤4例,腺混合瘤4例,神经鞘瘤3例,横纹肌肉瘤2例,非何杰金氏淋巴瘤1例进行B超、CT影像学分析。结果：发现这些肿瘤具有特征性的影像学表现,如海绵状血管瘤特征性的强回声可压缩性;神经鞘瘤的低回声、不可压缩性。CT扫描可显著病变形态、大小、位置、进行准确的空间定位,同时也可显示周围结构的继发改变。结论：对大于多数眼眶内肿瘤,B超联合CT检查既快捷又简单,影像学技术在眼眶肿瘤诊断中具有重要价值。

Iconography in the diagnosis of orbital tumour

Objective To evaluate the image characteristics of the B scan ultrasonography and computer tomography in the diagonosis of orbital tumour.Methods A total of 37 eyes of 37 patients with orbital tumour(10 orbital hemangioma,8 dermoid cyst,5 pseudotumour of orbit,4 malignent melanoma of chorioid,4 mixed tumor of lacrimal gland,3 neurilemmoma,2 rhabdomyosarcoma,1 non Hodgkin lymphoma)were involved,and the image characteristics of the B scan ultrasonography and computer tomography were analysed in the 37 patients.Results Some orbital tumours have characteristic manifestations respectively in iconography.Conclusions The B scan ultrasonography and computer tomography for diagnosis of some orbital tumours are fast and simple.It is very significant to select the technic of iconography for diagnosis of some orbital tumours.
