眼内肿瘤超声鉴别诊断及病理研究

The Ultrasonic Differential Diagnosis and Pat Hologic Study of Intraocular Tumor

目的为了研究眼内肿瘤的声像特点、鉴别诊断及其病理基础。方法回顾总结３４例患者术前的超声图像特点及鉴别要点，其中３０例术后作了病理检查。结果声像图为强回声的病变部位细胞丰富或组织致密或有钙化；弱回声或无回声区细胞稀少或有坏死、液化或液体渗出。结论病变部位的回声强度取决于该部位细胞数量、组织致密度及有无钙化。脉络膜黑色素瘤尾部的大量浆液渗出及坏死、液化是产生“挖空”现象的原因。

Objective To study the ultrasonic imaging character and differential diagnosis and pathologic basis of intraocular tumor.Methods 34 cases of patients ultrasonic imaging character and differential points were reviewing concluded. 30 cases of them have been made pathologic examination after operation.Results Where there are echoes in ultrasonic pictures, there are rich cells or compact tissues or calcifications, In weak echo place or no echo place, there are few cells, ncrosis, liquefaction or liquid exudation. Conclusion The ceho intensity of ultrasonic is determined not only by the cellular density, the compact degree of tissues but also by whether threr are calcifications or not. Amount serofluid exudation, necrosis and liquefaction in the tail like part of the choroid malignant melanoma is the reason for “dig hollow”phenomenon.
