| 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。 |

| Objective To analyze the imaging features of testicular solid lesions. Methods The CT and MR findings of 18 cases of testicular solid lesions confirmed by pathology were retrospectively reviewed. The location, attenuation/signal, size, shape, edge, and enhancement patterns of lesions were analyzed. Results In all of the 18 cases, 5 cases were seminomas, 1 of them was huge with punctate calcification, 4 of them had low signal separations in T2WI. Lymphomas were in 4 cases, and all of them were primary diffuse large B cell lymphoma; T2WI was priority with low signal. Solitary fibrous tumor was in 1 case, and the attenuation was lower than that of muscle. Embryo in sinus tumor were in 1 case, and the attenuation/signal was unhomogeneous; the continued enhancement liking grid was obviously seen after contrast injection. Nonspecific inflammatory masses were in 4 cases with involving epididymis in 2 cases, and the attenuation/signal was unhomogeneous. Tuberculous mass were in 3 cases, and 1 case with points of calcificationwas on the edge of lesion, 2 cases characterized by short T2 signals. Conclusion It is possible to make an accurate diagnosis by the combination of clinical data with imaging features in most of the testicular solid lesions. |
