Torsion of the spermatic cord: sonographic diagnosis

This article describes the ultrasound guidelines for evaluating patients with spermatic cord torsion, including gray-scale, Doppler with spectral analysis, and color and power Doppler sonography. The sonographic and Doppler features of acute, subacute, and chronic torsion of the spermatic cord are demonstrated and discussed.     

Lymphoma of the spermatic cord: Sonographic appearance

Primary lymphoma of the spermatic cord is a rare disease accounting for about 1.6% of primary spermatic cord tumors. We hereby present a new case in which color Doppler ultrasound (US), contrast‐enhanced US, and MRI suggested a specific diagnosis that was subsequently confirmed pathologically. Color Doppler US revealed mostly hypoechoic, slighly hypervascular tissue surrounding the normal spermatic vessels, which was markedly hypervascular at contrast‐enhanced US. MRI showed diffuse infiltration by homogeneously enhancing tissue surrounding the spermatic vessels hypointense to testis on T2‐weighted images, isointense on T1‐weighed images, lacking fat tissue, with relatively high signal intensity on diffusion‐weighted images. © 2014 Wiley Periodicals, Inc.

Four-dimensional and Doppler sonography in the diagnosis and surveillance of a true cord knot

Prenatal diagnosis of a true knot of the umbilical cord is often an incidental observation at ultrasound with a difficult differential diagnosis between true and false knots. Furthermore, little is known about the optimal management of these cases. We report the importance of color Doppler and four-dimensional ultrasound for the differential diagnosis in the case of true cord knot and the role of Doppler flow velocimetry in the management of that case.

Experimental study of the sonographic diagnosis of testicular torsion.

The sonographic and Doppler features of acute spermatic cord torsion were investigated in eight dogs. Serial sonography following torsion demonstrated unambiguous abnormalities in all experimental subjects within one hour. The observed abnormalities included increase in size of the spermatic cord, testis, and epididymis, decrease in echogenicity of the testis and epididymis, and loss of Doppler signal from the cord. Sonographic abnormalities were clearly visible before any histologic change was detected and well in advance of the onset of cellular necrosis. Since every experimental subject had an abnormal testicle, the identification of a normal testicle in a clinical setting is felt to exclude torsion. Combined gray-scale sonographic and Doppler features appear promising in the diagnosis of acute spermatic cord torsion and its distinction from acute epididymo-orchitis.     

Unusual masses in the spermatic cord: report of six cases and review of the literature.

Differential diagnosis of spermatic cord swellings includes direct inguinal hernia, hydrocele, spermatocele, hematocele, lipoma, tuberculosis, and filariasis. This communication focuses attention on other unusual swellings of the spermatic cord. Three cases of sarcoma, two cases of foreign body in the spermatic cord, and one case of vasitis are presented. Although unusual, these conditions should be considered in the differential diagnosis of spermatic cord swellings.     

三维超声成像在良恶性乳腺肿块鉴别诊断的价值

目的研究三维超声在二维彩色超声和X线钼靶照像(简称钼靶)诊断不同的乳腺疑难肿块中的鉴别诊断价值。方法对我院二维彩色超声和钼靶定性不同的35个乳腺肿块,研究其三维超声成像的特点,并与手术、病理结果进行对照分析。结果乳腺肿块超声和钼靶检查经手术病理确诊的148个肿块中,两种方法定性不同的35个肿块占23.6%,钼靶误诊17个肿块,误诊率为11.5%;二维彩色超声误诊18个肿块,误诊率为12.2%(与乳腺纤维囊性增生症患者混淆的15例,占83.3%),通过三维超声灰阶表现汇聚征和冠状切面来判断其良恶性,误诊率降低为2.7%(4/148)。结论三维容积超声成像可观察到二维超声所不能显示的冠状切面,更直观、更形象地获得肿块立体形态及与周围组织的关系,提高了彩色超声对乳腺纤维囊性增生症的良恶性鉴别诊断的正确性,但对无症状的乳腺慢性炎症和常规超声漏诊病例尚需造影等进一步检查。
