睾丸肿瘤的超声表现

目的 探讨睾丸肿瘤的超声表现及超声在睾丸肿瘤诊断中的应用价值。方法 回顾性分析经手术、病理证实的34例睾丸肿瘤的二维及彩色多普勒血流声像。结果 睾丸良恶性肿瘤超声图像共同特征：睾丸增大，内见占位病灶。其中，睾丸良性肿瘤9例，睾丸肿块边界多数较清，边缘较规则，CDFI示团块内部及周边无血流信号或少许血流信号；睾丸恶性肿瘤25例，其肿块边界不清，边缘欠规则，CDFI示团块内部及周边有血流信号，甚至为较丰富的血流信号。结论 超声检查睾丸肿瘤，无创伤性，图像清晰、直观，二维声像结合CDFI能对睾丸肿瘤良恶性做出鉴别诊断，具有较高的临床应用价值。

Ultrasonographic features of testicular tumors

Objective To evaluate the ultrasonography in diagnosis of testicular tumors. Methods Findings of high - frequency ultrasound and CDFI were retrospectively studied in 34 cases of testicular tumors that were confirmed by post - surgical pathology. Results The enlarged testes with space - occupying lesions were detected in all cases. The benign tumors had showed clear and regular margin in 9 cases. And there was no signal or hypo ?signal of blood flow within and surrounding the lesions on CDFI. Blurred and irregular margin of malignant tumors is revealed in 25 cases. Blood flow and in some cases, abundant blood flow within and surrounding the tumors were shown on CDFI in those cases. Conclusions Ultrasonography is a non ?invasive and intuitive examination providing quality imaging. High - frequency ultrasonography and CDFI are valuable in differentiating the benign testicular tumors with malignant ones.
