眼内恶性肿瘤的影像学诊断价值

目的：评价B超、CT、MRI对眼内恶性肿瘤的诊断价值。方法：将106例临床诊断为眼内恶性肿瘤病人的门诊初步诊断、B超诊断、CT诊断、MRI诊断和术前诊断与病理诊断进行对比分析,计算各种诊断的误诊率。统计106例病人的并发症。结果：106例中临床诊断（术前诊断）为视网膜母细胞瘤80例、脉络膜黑色素瘤18例,脉络膜转移癌8例,获得病理证实分别为79你、18例和7例。各阶段诊断误诊率分别为门诊初步诊断44.34％、B超诊断4.72％、CT诊断16.09％、MRI诊断误诊率为0,术前诊断1.89％。继发青光眼占33.96％、继发视网膜脱离占30％、屈光间质混浊占24.53％。结论：眼内恶性肿瘤并发症较多,易造成误诊。B超、MRI影像技术各有优势和不足,合理选择配合使用能大大降低误诊率。

Diagnostic value of imaging examination for malignant tumor in ocular globe

Objective To evaluate the diagnostic vlaue of ocular globe malignant tumors by ultrosond-B,CT and MRI examiniation.Methods 106 cases diagnosted clinically as malignant tumor in ocular globe were analyzd,and the diagnosis of priliminary outpatient department,Ultrasonography,CT,MRI and preoperative were comparaed with their histopathologic diagnosis.The complications in 106 cases were count also.Results 104 in 106 cases were confirmend histopathologically,The misdiagnosis ratio of preoperative was 1.89%,and other stage misdiagnostic ratio each was preliminary outpatient department 44.34%,Ultrasonography 4.72%,CT 16.09% and MRI was zero.The complication incidence were secondary glaucoma 33.96%,secondary retinal detachment 30% and refractive matter opacity 24.53%.Conclusions The malignant tumors were misdiagnosed easily because these clinical complications were more prepondernant than their own manifestations.It's effective way to avoid misdiagnosis of these tumors to make reasonable choice of ultrosonad-B,CT and MRI.
