目的探讨核磁共振成像(MRI)用于睾丸附睾肿块诊断的临床价值。方法回顾性分析经广东省农垦中心医院手术及病理学检查确诊的1 6例睾丸附睾肿块患者的影像学资料,分析其MRI表现。结果 1 6例睾丸附睾肿块病灶MRI影像显示不同程度的肿大,边界清或不清。其中精原细胞瘤5例,以实质性改变为主,病灶内见均匀等T1、T2信号及大小不等片状长T1、T2信号,病灶轻度强化;混合型生殖细胞瘤2例,MRI表现T1 WⅠ、T2 WⅠ呈高混杂低信号;畸胎瘤3例,良性畸胎瘤呈椭圆形,T1 WⅠ、T2 WⅠ呈高混杂低信号及轻度强化,恶性畸胎瘤增强后呈不均匀明显强化;内胚窦瘤(卵黄囊瘤)1例,边缘欠规整,T 2 WⅠ高信号及不均匀强化;附睾囊肿及附睾结核各发生1例;非特异性肿块3例。结论M R I的多方位、多序列扫描能清楚显示睾丸附睾病变,对早期诊断及治疗有较高的价值。
Objective To investigate the clinical value of magnetic resonance imaging (MRI) in the diagnosis of testicular epididymis mass. Methods The imaging data of 16 cases of testicular epididymis masses diagnosed by operation and pathology examination of Guangdong Provincial Land Reclamation Center Hospital were retrospectively analyzed and their MRI findings were analyzed. Results 16 cases of testicular epididymal lesions MRI images showed varying degrees of swelling, border clear or unclear. Seminoma in 5 cases, with substantial changes in the main, uniform lesions within the T1, T2 signal and the size of the patchy long T1, T2 signals, mild focal enhancement; mixed germ cell tumor in 2 cases, MRI T1WI, T2WI showed a high mixed low signal; teratoma in 3 cases, benign teratoma was oval, T1WI, T2WI showed high mixed low signal and mild enhancement, malignant teratoma enhanced uneven 1 cases of endodermal sinus tumor (yolk sac tumor), the edge of the defect, T 2 W Ⅰ high signal and uneven enhancement; epididymal cyst and epididymal tuberculosis occurred in 1 case; non-specific mass in 3 cases. Conclusion Multi-orientation and multi-sequence scanning of M R I can clearly show the lesions of the testis and epididymis, which is of great value in the early diagnosis and treatment.
