原发性睾丸淋巴瘤超声表现及误诊分析

目的探讨原发性睾丸淋巴瘤的超声表现特征。方法回顾性分析21例经病理证实为睾丸淋巴瘤的常规超声及超声造影表现,分析其超声表现特点,并对相关病例的误诊情况进行探讨。结果 21例行常规超声检查的病灶中,有13例(61.9%)为弥漫型,8例(38.1%)为结节型,病灶最大径线6～60mm,平均约(40.8±15.0)mm;病灶边界清楚的有18例(85.7%),边界不清楚的有3例(14.3%);12例(57.1%)病灶形态规则,9例(42.9%)病灶形态不规则;病灶呈均匀性低弱回声的有14例(66.7%),呈不均匀性低弱回声的有7例(33.3%);所有病灶血流信号均呈Ⅲ级。11例行超声造影检查的病灶均呈快进高增强,病灶呈均匀性增强的有9例(81.8%),呈不均匀性增强的有2例(18.2%);造影剂消退时间24～51s,平均约(38.1±6.1)s;术前超声检查对本研究睾丸疾病诊断准确率为81.0%(17/21),误诊为精原细胞瘤3例(14.2%),误诊为炎性病变1例(4.8%)。结论睾丸淋巴瘤常规超声及超声造影具有一定特征,学习及掌握其特点可以更好的提高睾丸淋巴瘤诊断准确率,为临床进一步诊疗提供...

Analysis of Routine Ultrasound and Contrast-enhanced Ultrasonography and Misdiagnosis of Primary Testicular Lymphoma

Objective To investigate the ultrasonographic features of primary testicular lymphoma.Methods A retrospective analysis of 6 cases of pathologically confirmed testicular lymphoma was performed by conventional ultrasound and contrast-enhanced ultrasonography.The characteristics of the ultrasound were analyzed and the misdiagnosis of related cases was discussed.Results Of the 21 cases examined by routine ultrasound,13 cases(61.9%)were diffuse,8 cases(38.1%)were nodular,and the longitude of the lesion ranged from 6 mm to 60 mm,with an average of(40.8±15.0)mm;18 cases(85.7%)had clear boundary,3 cases(14.3%)had unclear boundary;12 cases(57.1%)had regular shape and 9 cases(42.9%)had irregular lesions.14 cases(66.7%)showed homogeneous hypoechoic lesions and 7 cases(33.3%)showed inhomogeneous hypoechoic lesions.The blood flow signals of all lesions were gradeⅢ.The lesions examined by contrast-enhanced ultrasonography showed rapid and high enhancement in all11 cases,9 cases(81.8%)showed homogeneous enhancement,2 cases(18.2%)showed heterogeneous enhancement;the time of contrast agent disappearance ranged from 24 seconds to 51 seconds,with an average of(38.1±6.1)seconds.The diagnostic accuracy of preoperative ultrasonography for testicular diseases was 81.0%(17/21),3 cases(4.8%)were misdiagnosed as seminoma(14.2%)and 1 case was misdiagnosed as inflammatory lesion.Conclusions Conventional ultrasound and contrast-enhanced ultrasonography of testicular lymphoma have certain characteristics.Learning and mastering the characteristics can improve the accuracy of diagnosis of testicular lymphoma and provide more and more reliable information for further clinical diagnosis and treatment.
