睾丸肿瘤的二维及彩色多普勒超声的诊断分析

Evaluation of ultrasound diagnosis of testicular tumor

目的 探讨二维及彩色多普勒超声显像在诊断睾丸肿瘤疾病中的价值。方法 用黑白及彩色超声诊断仪对睾丸肿瘤进行扫查,仔细观察病变部位,同时记录病灶大小、内部回声及其与周围组织的关系,并用彩色多普勒记录肿瘤内血供及阻力指数。结果 本组39例中,均经手术和病理证实,二维超声诊断符合率为92.3％(36/39)。39例睾丸肿瘤中,33例为恶性;6例为良性,其中1例为附睾结核。恶性肿瘤中以精原细胞瘤最多,占45.5(15/33),其次为淋巴瘤。39例睾丸肿瘤的声像图表现可分为无回声、均匀性低回声、高回声、实质不均质回声四种类型。其中淋巴瘤的超声图像表现为低回声型,精原细胞瘤大都表现为实质不均质、也有呈低回声,其余类型恶性肿瘤均为实质不均质型。本组中11例进行彩色多普勒检查。恶性肿瘤均为富血供型肿瘤,阻力指数较低,平均为0.58;而良性肿瘤未见彩色血流。结论 二维及彩色多普勒超声是诊断睾丸肿瘤的重要手段。

Purpose To evaluate the value of ultrasonography in diagnosis of testicular tumors Methods The testicular tumors were scanned by gray - scale ultrasound and color Doppler instrument. The sizes and the internal echoes of tumors were observed and recorded carefully. Results All these patients were operated and confirmed by pathology. The accurate rale of two - dimensional ultrasound was 92.3 % (36/39) in the diagnosis of testicular tumors. During 39 patients, 33 were malignant and 6 were benign. The echoic patterns of tesicular tumors were classified as anechoic, hypoechoic , hyperechoic and inhomogeneous patterns. The ultrasonograms of lymphoma were hypoechoic lesion while seminomas were inhomogeneous or hypoechoic and other tumors were all inhomogeneous lesions. Of them, 11 patients were examined by color Doppler How imagining( CDFI). The malignant tumor was rich of blood supply on color Doppler map. The resistance index was lower, but the color flow was not displayed in benign tumors. Conclusions Ultrasonography and CDFI are important methods in the diagnosis of testicular tumor.
