摘要
目的评价小儿未降睾丸的MRI表现及其临床价值。方法对36例年龄在1~14岁临床发现阴囊空虚病人行MRI检查,33例单侧阴囊空虚,3例双侧阴囊空虚,34例经手术证实,2例因MR未检出未降睾丸而未行手术探查。回顾分析其MR表现并与手术结果对照。结果MRI正确显示未降睾丸34例(37枚),检出率94.4%(34/36),并经手术证实,34例中31例为单侧,3例为双侧,其中2例为异位睾丸,8例合并斜疝。结论无创性、无辐射性、多方位成像的MRI能揭示小儿未降睾丸的解剖及组织学特征,图像清晰直观,最佳的成像平面为横断位及冠状位。有利于对并发症提供一定依据。
Objective To evaluate the clinical value and findings of MR in children with undescended testis. Methods 36 children with vacant scrotum underwent MR scanning, who had single vacant scrotum in 33 patients and both sides in 3 patients. Their age was from 1 to 14 years old, Thirty-four cases were approved by operation. The operation had not been performed because of failure to localize the testes with MR in the other 2 cases. The results of operation were compared with MR findings retrospectively. Results Thirty-four(of 37)cases with undescented testes were displayed on MR. The accuracy rate was 94.4%(34/36). Of 34 patients, there were 31 in single side, 3 in both sides. Two cases were ectopic testis and 8 cases were accompanied by oblique hernia. Conclusion MR imaging ,with the advantages of noninvasive, nonradiation, multiplanar capability and clear and direct imaging, can also visualize the anatomical and histological characteristics of undescended testis.The imaging were showed clearly and directly. The optimal imaging planes are the axial and coronal planes. MRI can provide some information in the evaluation of complication.
