研究后部眼球壁灰褐色隆起物——脉络膜血肿及脉络膜黑色素瘤的声像学表现 ,以便对其进行声像学鉴别诊断。方法 :对 FFA确诊为脉络膜血肿和手术病理证实为脉络膜黑色素瘤的 17例患者 B超检查所见 ,进行声像学分析。结果 :9例脉络膜血肿患者 ,B超检查表现为 :6例后极部球壁局限性增厚 ,随增益降低出现层间透声裂隙 ,增益越低透声裂隙越明显 ,裂隙中散在弱回声光点 ;3例病变范围大、隆起高 ,与浅层视网膜脱离相似 ,但其光带较厚 ,缺乏后运动 ,且膜下见细小弱回声光点。 8例脉络膜黑色素瘤中 5例表现为球壁半球形实性隆起物 ,3例为蘑菇形。肿物在声像图上均表现为前缘光滑锐利 ,内回声前方多而强 ,向后渐少而弱 ,见脉络膜凹陷及后方声影 ,3例蘑菇形肿物均见头部周围及附近视网膜浅层脱离。结论 :脉络膜血肿与脉络膜黑色素瘤的声像学表现有明显差异
To study the posterior ocular wall gray brown bumps - choroidal hematoma and choroidal melanoma imaging performance, so that its differential diagnosis of ultrasound. Methods: Seventeen patients diagnosed with choroidal hematoma by FFA and choroidal melanoma confirmed by surgery were examined by sonography. Results: In 9 patients with choroidal hematoma, the results of B ultrasound examination showed that the posterior pole of the posterior wall of the 6 patients was thickened, with the decrease of gain, the sound and the crevasse of the interlayer appeared. The lower the gain was, the more obvious the sound and the fissure were. Sound and light spots; 3 cases of lesions range, raised high, similar to the shallow retinal detachment, but the light band thicker, lack of exercise, and the film see the small weak echo spots. In 8 cases of choroidal melanoma, 5 cases showed spherical hemispherical solid bumps and 3 cases were mushroom-shaped. Tumors in the sonography showed the front edge smooth and sharp, the front of the echo more and more strong, back less and less, see the choroidal pits and the back of the sound shadow, 3 cases of mushroom-shaped tumor were seen around and around the head Retinal shallow detachment. Conclusion: The choroidal hematoma and choroidal melanoma have significant differences in sonographic features
