摘要：目的：探讨睾丸微小结石症(testicular microlithiasis ,TM)的超声影像特征及其临床意义。方法：回顾性分析71例睾丸微小结石症患者的超声图像。结果：71例睾丸微小结石症中3例发生于单侧睾丸，68例累及双侧睾丸，可合并精索静脉曲张、附睾头囊肿、睾丸发育不良等。超声影像特征为：睾丸实质内可见散在稀疏或密集分布的强回声光点，直径约1mm左右，后方无声影。结论：睾丸微小结石症是一种良性病变，与不育和睾丸肿瘤有关，必需定期随访复查。

    Abstract: Objective: To study the ultrasonographic features and clincal significance of testicular microlithiasis (TM) . Method: The ultrasonographic of 71 cases with testicular microlithiasis were retrospectively analyzed. Result: Of 71 cases , 3 cases were associated with one testis . 68 cases were associated both testis. Testicular microlithiasis may be complicated with varicocele, epididymis cyst, testicle hypogenitalism. Ultrasonographic features: Sonographic examination of testis revealed depictions of rare, diffuse hyperechoic foci in the parenchyma of testis. These foci were about 1 mm in diameter and without acoustic shadows. Conclusion: Testicular microlithias is often occurs in the patient with infertility and testiculoma.Therefore, it is necessary that patients with testicular microlithiasis should be periodically followed up and observed ultrasonographically. ......
