摘　　要：目的分析小儿睾丸、附睾肿瘤和炎性肉芽肿影像学特点,提高诊断准确性。方法全部13例行超声检查。CT平扫10例,其中增强6例。回顾性分析13例儿童睾丸、附睾肿瘤和炎性结节的影像学表现,并与手术及病理结果相对照。结果超声检查:13例均有内部回声强弱不等、分布不均匀,8例肿瘤内血流信号丰富,3例少血流信号,2例无血流信号,腹膜后淋巴结转移2例。CT平扫呈混杂密度4例,3例有钙化,软组织密度或绝大部分软组织密度6例。增强明显不均匀强化4例,轻度强化1例,无强化1例。手术证实成熟性畸胎瘤3例,未成熟畸胎瘤1例,卵黄囊瘤4例,附睾急、慢性炎症3例,淋巴管瘤1例,横纹肌肉瘤1例。结论小儿睾丸肿瘤的超声及CT具有各自特点,2种方法结合能明显提高术前诊断准确率。Objective To analyzed imaging features of testicular and epididymal tumors or inflammatory nodes in children and to improve its diagnostic accuracy. Methods 13 cases underwent ultrasonography, of them, plain CT scan in 10 cases, enhanced CT scan in 6 cases . Its signs were retrospectively analyzed and compared with surgical and pathological results . Results On ultrasonography , the inhomogenous and different echo could be viewed in 13 cases, color Doppler flow imaging was abundant in 8 masses , 3 cases with littler, empty blood flow in 2 cases and retroperitoneal lymphatic metastasis were viewed in 2 cases. On plain CT scan, masses were mixed density in 4 cases, calcification could be seen within tumor in 3 cases, masses were soft tissue or main soft tissue density in 6 cases. Contrast - enhanced CT scan displayed obviously and inhomogenously in 4 cases , lightly enhancment in 1 case and no enhanced in 1 case . By surgical and pathological confirmed , 3 were mature treatomaes , 1 was immaturity teratoma , 4 were yolk sactumor , 3 were inflammatory nodes , 1 was rhabdomyosarcoma and 1 was cystic lymphangioma . Conclusion Each kind of testicular tumors in children has its owns CT and US characteristics. In combination of CT and US can carry high diagnostic accuracy.
