眼内及眶内肿瘤的超声及临床手术、病理对照分析

The Ultrasonic imaging on eye or orbit tumor and the Contrast analysis of the clinical operation as well as pathology

目的 对眼内及眶内肿瘤超声检查与临床手术及病理进行对照分析以探讨超声对眼内及眶内肿瘤的诊断价值。方法 用高频探头对眼内及眶内肿瘤患者进行多切面扫查以观察肿物的声像图特征。结果 (1)超声检查对视网膜母细胞瘤的诊断符合率为 10 0 %。根据年龄特点 5岁以内儿童 ,白瞳孔超声示眼内低回声占位伴钙斑。 (2 )脉络膜黑色素瘤诊断符合率为 75 % ,特征是瘤体后方回声减弱 ,并伴网脱。 (3)血管瘤特点 :瘤体回声较强 ,隆起度不超过 5～ 6mm ,瘤体基底部有多数血流 ,频谱为低阻型。 (4)泪腺混合瘤多发生在泪腺部 ,一个或多个低回声结节为特点。 (5 )血肿 :一般有外伤史 ,加之彩色多普勒可见粗大的血管 ,多见于A -V瘘 ,外伤后易破裂形成眶内血肿。 (6 )转移瘤 :在原发灶不明确的情况下不易诊断瘤体的性质 ,但瘤体血流丰富。结论 超声检查眼内眶内占位病变具有方便、无创伤、直观的优点 ,只要掌握瘤体的特征 ,并结合年龄、病史特点 。

Objectives To make contrast analysis with ultrasonic imaging on eye or orbit tumor and clinical operation as well as pathology,in order to discuss diagnosis value of ultrasonic on eye or orbit rumor.Methods High frequency probe is applied in 20 cases of eye and orbit tumor with multiple setions to observe the features of ultrasonic imaging.Results (1)Diagnose coincidence rate of Retinoblastoma by ultrasonic examination is 100%,which is based on eye feature-children less than 5 years old,white pupil,low level echo place holder with calcification.(2)Diagnosis coincidence rate of choroid melanoma is 75%,It is show that the weakning of echo at the backside of tumor,accompanied by Retinal Detachment.(3)The features of Hemangioma are:the echo of tumors is comparatively strong.the size of apophysis is less than 5～6mm,there are many color bloodstreams at the bottom of tumors with the less Acoustic impedance of frequency spectram.(4)Mixed Tumor of Lacrimal Gland is mormally found at locrimal Gland with one or more nodes having low level echo.(5)Hematoma:It is very often has wound history and is observed with thick and big blood vessels in Hrtery-vein fistula.By the use of color Doppler flow imaging orbit hematoma is easily formed by the break being wounded.(6)The Metastasis Tumor:It is difficult to diagnose the features of the Tumor if the primary focus is uncertain.However,the bloodstream around the tumor is plentiful.Conclusions Intuitive and woundless are the advantages of the ultrasonic examination on the placeholders in the eye or orbit.A Sound diagnosis of the common tumor pathogeny can be made by the well knowing of the features of tomor,along with the age and history of illness.
