摘要
目的:探讨睾丸肿瘤与肿瘤样病变CT/MRI诊断与鉴别诊断特征,提高术前定性诊断的准确率。方法:睾丸肿瘤与肿瘤样病变20例,所有患者均行CT或MRI检查;并最终经病理学证实。17例患者行CT检查,层厚3mm,层距3mm。MRI检查者为17例,采用T1WI、T2WI、T2WI脂肪抑制等序列扫描。结果:20例均为单侧发病-左侧11例,右侧9例;其中精原细胞瘤14例,良性肿瘤或肿瘤样病变6例:包括成熟型囊性畸胎瘤3例、腺瘤样瘤2例、纤维性假瘤1例,这3种良性病变在密度或信号、是否合并钙化及病灶大小等方面均有不同于精原细胞瘤的影像学表现。结论:睾丸肿瘤与肿瘤样病变的大小、密度、边缘、强化程度等情况,病灶内是否合并钙化及钙化的形态,对判断病变的良恶性有一定帮助。
Objective:To study the features of CT/MRI imaging diagnosis and differential diagnosis of testicular tumor and tumor-like lesionsi.Methods: In all 20 cases confirmed by pathology,CT or MRI examination were performed.In 17 cases,CT exam were performed with a section thickness and interval of 3 mm.MRI exam were performed with T1WI,T2WI and T2WI fat-suppression sequence in 17cases.Results: All 20 cases were found in one side testicle,11 cases in left side,9 cases in right side.The cases included seminoma(14 cases) and benign tumor-like lesions(6 cases): mature cystic teratoma(3 cases),adenomatoid tumor(2 cases),fibro-pseudinomal(1case).There were different imaging finds in density/signal,calcification,size and so on between 3 kinds of benign lesions and seminoma.Conclusion: It is helpful to diagnosis of testicular benign or malignant lesions to analyze lesions' size,density,edge,enhancement level,calcification and its shape completely.
