【摘要】：目的分析睾丸实性肿块性病变的影像学特征。方法回顾性分析18例经病理证实的睾丸实性肿块性病变的CT、MR影像资料,对病灶的部位、密度/信号、大小、形态、边缘以及强化方式等进行分析。结果 18例实性肿块性病变中精原细胞瘤5例,1例肿块巨大,伴点状钙化,4例T2WI可见低信号分隔;淋巴瘤4例,均为原发性弥漫大B细胞淋巴瘤,T2WI以低信号为主;孤立性纤维瘤1例,密度低于肌肉;内胚窦瘤1例,密度/信号不均匀,增强均呈明显网格状持续强化;非特异性炎性肿块4例,2例累及附睾,密度/信号不均;结核性肿块3例,1例边缘可见钙化点,2例表现为稍短T2信号为主的混杂信号肿块。结论结合患者临床及影像学特征,部分睾丸实性肿块可明确诊断。
[Abstract]:Objective to analyze the imaging features of testicular solid mass lesions.Methods the CT Mr imaging data of 18 cases with pathologically proved solid testicular mass lesions were analyzed retrospectively. The location, density / signal intensity, size, shape, edge and enhancement mode of the lesions were analyzed.Results in 18 cases of solid mass lesions, 5 cases of seminoma had a large mass and 4 cases of T2WI with dot calcification showed hypointensity separation, 4 cases of lymphoma were primary diffuse large B-cell lymphoma with low signal intensity on T _ 2WI, and 4 cases had low signal intensity on T _ 2WI, and 4 cases of lymphoma were characterized by hypointensity on T _ 2WI.In 1 case of solitary fibroma, the density was lower than that of muscle, the density / signal of endodermal sinus tumor in 1 case was uneven, and the enhancement was obviously reticular and continuous enhancement, non-specific inflammatory mass in 4 cases involved epididymis in 2 cases, and the density / signal intensity was uneven.In 3 cases of tuberculous mass, calcification was seen on the margin of 1 case. 2 cases showed mixed signal mass with slightly short T 2 signal intensity.Conclusion combined with clinical and imaging features, some solid testicular masses can be clearly diagnosed.
