| 目的 分析成人睾丸肿瘤和肿瘤样病变的常规超声和超声造影特征，探讨超声造影对其的鉴别诊断价值。方法 回顾性分析40例经手术病理证实的睾丸肿瘤、肿瘤样病变患者（睾丸肿瘤组26例、肿瘤样病变组14例）的常规超声和超声影像检查资料，比较两种疾病的影像学特征，分析超声造影对其的诊断效能。结果 睾丸肿瘤组、肿瘤样病变组在病变大小、形态及回声的均匀性比较，差异均有统计学意义（均P＜0.05）；在超声造影增强程度、增强形态、增强模式及“假包膜”征象比较，差异均有统计学意义（均P＜0.05）。常规超声对睾丸肿瘤的诊断敏感性、特异性及正确率为88.5%、64.3%及80.0%；超声造影对睾丸肿瘤的诊断敏感性、特异性及正确率为100%、92.9%及97.5%。在常规超声和超声造影两种方法中，Z=1.835，P=0.0665，两种方法不存在统计学差异。结论 超声造影特征有助于不同类型睾丸肿瘤与肿瘤样病变的鉴别诊断，具有重要的临床价值。 |

| Abstract: |
| Objective Analyze the characteristics of conventional ultrasound and contrast-enhanced ultrasound in adult testicular tumors and tumor-like lesions，and explore the value of contrast-enhanced ultrasound in their differential diagnosis. Methods Retrospectively analyze the conventional ultrasound and ultrasound imaging data of 40 patients with testicular tumors and tumor-like lesions confirmed by operation and pathology(26 cases in the testicular tumor group and 14 cases in the tumor-like lesion group)，compare the imaging characteristics of the two diseases，and analyze the diagnostic efficiency of contrast-enhanced ultrasound. Results Comparison of the size，morphology and echo uniformity of the testicular tumor group and tumor-like lesion group was statistically significant(all P＜0.05). There were statistically significant differences in enhancement intensity，enhancement shape，enhancement mode and "pseud-capsule" sign（all P＜0.05）. The sensitivity，specificity，and accuracy of conventional ultrasound in the diagnosis of testicular tumors were 88.5%，64.3%，and 80.0%. The sensitivity，specificity，and accuracy of contrast-enhanced ultrasound in the diagnosis of testicular tumors were 100%，92.9%and 97.5%. In conventional ultrasound and contrast-enhanced ultrasound，z = 1.835，P = 0.0665，there was no statistical difference between the two methods. Conclusion Combined with a variety of CEUS features，it is helpful for the differential diagnosis of different types of testicular tumors and tumor-like lesions. |
