摘　　要：目的探讨CT在睾丸肿瘤的CT诊断价值。方法回顾性分析经手术病理证实的34例睾丸肿瘤的组织病理、临床特点及其CT表现。结果 34例CT均表现为睾丸肿大,呈软组织密度。其中精原细胞瘤17例,CT表现为肿瘤有完整或不完整的包膜,呈实性改变为主,可见不同程度的低密度,轻度—中度分隔样强化。混合性生殖细胞瘤5例,卵黄囊瘤2例,CT表现为包膜完整的囊实性包块,增强后明显不均一强化。胚胎性癌1例,CT表现为包膜不完整的囊实性肿块,增强后轻度不均一强化。畸胎瘤4例,其中良性畸胎瘤2例,CT表现为包膜完整的囊实性肿块,内见粗在环状钙化,并可见脂肪密度,增强后轻度不均一强化。恶性畸胎瘤2例,CT表现为包膜完整的实性肿块,其内未见钙化及脂肪密度,增强后轻度不均一强化。淋巴瘤2例,CT表现为睾丸实性块,密度均匀,增强后均一强化。高分化脂肪肉瘤1例,CT表现为包膜完整的实性软组织肿块,内见脂肪密度及点状钙化,增强后呈不均一强化。腺瘤样瘤1例,CT表现为实性肿块,内见坏死。增强后轻度不均一强化。表皮样囊肿1例,CT表现为包膜完整囊性肿块,增强后无强化。结论 CT能明确检出睾丸肿瘤,结合患者发病年龄及临床资料可对不同病理类型的睾丸肿瘤作出诊断及鉴别诊断,也能显示淋巴结及远处转移情况,为肿瘤的分期和临床制订治疗方案提供参考。Objective To discuss the diagnostic value of CT in testicular tumor. Methods Histopathology, clinical fea- tures and CT manifestations of 34 cases with testicular tumor proved surgically and pathologically were analyzed retrospec- tively. Results Testis enlargement was seen in CT images of 34 cases and the density was the same as the soft tissues. On contrast CT scan, 17 cases with seminoma showed the tumor with complete or incomplete capsule, and solid changes main- ly. The density of the tumors showed different degrees of low density, and slight to medium separate enhancement. CT manifestations of the 5 cases with mix germ cell tumors and 2 cases with yolk sac tumors showed cystic and solid masses with complete capsules, and showed marked inhomogeneous enhancement. CT manifestations of the 1 case with embryonal carcinoma showed cystic and solid tumor with incomplete capsule, and showed slight inhomogeneous enhancement. Of 4 cases with teratoma, the contrast CT scan of 2 cases with benign teratoma showed cystic and solid masses with complete capsules, and annular coarse calcification and fat-density were seen inside,and showed slight inhomogeneous enhancement. 2 cases with malignant teratoma showed solid tumors with complete capsules, and no calcification and fat-density were seen. The contrast CT scan showed slight inhomogeneous enhancement. On contrast CT scan, 2 cases with lymphoma showed solid tumors in testis ,with even density, and homogeneous enhancement. 1 case with well differentiated liposarco- ma showed soft tissue tumor with complete capsule, and calcification spots and fat-density was seen inside. The contrast CT scan showed inhomogeneous enhancement. 1 case with adenomatoid tumor showed soft tissue tumor and necrosis was seen inside. The contrast CT scan showed slight inhomogeneous enhancement. The CT of 1 case with epidermoid cyst showed cystic mass with complete capsule and no enhancement on the contrast CT scan. Conclusion CT can detect testic- ular tumor definitely. Based on the age of onset an
