睾丸附睾感染性病变MRI诊断分析

MRI PERFORMANCE AND DIAGNOSIS ANALYSIS OF TESTIS AND EPIDIDYMIS INFECTION LESIONS

目的：探讨睾丸附睾感染性病变的 MRI 表现。方法：10例睾丸附睾感染性病变病人均行磁共振成像（MRI）检查,扫描序列包括常规 T1WI、T2WI＋FS、DWI 及 LAVA,扫描方位为横断面、矢状面及冠状面,层厚3~4mm,从不同扫描序列及扫描方位图像观察病变部位、大小、形态、信号及其与周围组织关系,并与手术病理及临床结果对比。结果：睾丸附睾非特异性炎症6例,睾丸附睾结核4例。MRI 对睾丸附睾病变定位准确,感染性病变的 MRI 表现有一定特点,特别是结核。结论：MRI 的多方位、多序列扫描技术可清晰显示睾丸附睾感染性病变及其与周围组织的关系,推测其可能组织成分,有助于病变的诊断与鉴别诊断。

Objective：To study the magnetic resonance imaging （MRI）performance of testis and epididymis infection lesions.Methods：MRI scan was performed in 10 patients with testis and epididymis infection lesions.The scanning sequences included T1-weighted image,T2-weighted image with fat suppression,DWI and LAVA.Scanning was performed in sagittal, coronal and axial plane,and slice thickness varied from 3.0 to 4.0mm.The location,size,shape, and signal of the lesions were observed and analyzed.MRI performance was compared with the results of pathology,surgery and clinical diagnosis.Results：6 cases were nonspecific epididymo-orchitis,and 4 cases were tuberculous epididymo-orchitis.MRI had great help in making sure of the location of the lesions.Infection lesions of testis and epididymis had characteristic imaging performace on MRI,especially tuberculosis.Conclusions：The MRI scanning technique with multiple planes and multiple sequences could clearly show the infection lesions in testis and epi-didymis,including its relationship with the surrounding tissues.The possible histologic components could also be deduced according to MRI performance.So MRI is helpful for the di-agnosis and differential diagnosis of the lesion.
