【摘要】 目的:探讨超声检查在小儿睾丸微小结石症(TM)诊断中的应用价值。方法:应用高频线阵探头,诊断6例TM,同时进行随访和复查。结果:儿童声像图与成人一样,表现为单侧或双侧睾丸实质内弥漫分布≤2mm,无声影的强光点,其中3例1侧隐睾,1例双侧隐睾,2例鞘膜积液,病理改变为曲细精管内多发分层状钙化,2例超声和临床随访无恶性变。结论:高频超声对TM诊断起到重要作用,小儿TM常因阴囊其它疾病行超声检查时确诊。因有睾丸肿瘤发生的倾向,需定期6~12个月超声检查。更多还原

【Abstract】 Objective:To investigate the application value of ultrasonic diagnosis in children’s testicular mierolithiasis.Methods:Six cases of TM were diagnosed with high-frequency linear array probe(direct detection) and trace and countercheck were carried throught.Results:The acoustic images of TM children were as the same as those of TM audles.They appeared to be strong echogenic dots,less than 2mm and without acoustic shadows,distributing in the parenchyma of unilateral or bilateral testicle.The distributions of echogenic dots could be divided into two types: the diffuse type and the peripheral type.Among these six cases three patients were unilateral cryporchism.One bilateral cryptorchism and two hydrocele of tunica membrane.Pathological changes were multiple and layered califications in the curly deferent ducts.Two case had no malinant changes through the ultrasonic and clinical trace.Conclusion:High frequency ultrasound has played an important part in the diagnosis of TM.While Dopple ultrasound has no differential diagnosis.Children’s TM is often diagnosed when scrotum is examined by ultrasound for other disease.Children of TM should be termly checked by ultrasound about 6~12 months because of the inclining to testicular tumor.更多还原
