Testicular microlithiasis (TM), which usually affects both testes, is diagnosed primarily by ultrasound. TM has been found to be associated with benign conditions but has also been reported in association with testicular cancer. Echographically, TM is manifested by diffuse, punctate, non-shadowing, hyperechoic foci within the testicular parenchyma. To date, more than 80 cases of TM have been documented sonographically or pathologically; 25 of them have demonstrated an association with pathologically proven testicular cancer (p < 0.05). Thirty-two cases were associated with infertility/subfertility (p < 0.05). We believe the finding of TM on ultrasound should heighten the radiologist's suspicion of testicular malignancy. If no malignancy is identified on initial evaluation including CT of the chest and abdomen, close clinical follow-up with periodic (every 6 to 12 months) scrotal ultrasound examination is probably indicated.
睾丸微石症（TM）通常累及双侧睾丸，主要通过超声进行诊断。已发现TM与良性疾病有关，但也有报道称其与睾丸癌有关。在超声检查中，TM表现为睾丸实质内弥漫性、点状、无阴影的高回声灶。迄今为止，超声或病理记录的TM病例已超过80例；其中25例显示与经病理证实的睾丸癌有关（p < 0.05）。32例与不育/亚生育有关（p < 0.05）。我们认为，超声检查发现TM应提高放射科医生对睾丸恶性肿瘤的怀疑。如果在包括胸部和腹部CT在内的初始评估中未发现恶性肿瘤，可能需要进行密切的临床随访，并定期（每6至12个月）进行阴囊超声检查。
