急性睾丸节段性梗死的超声表现

The Ultrasonographic Findings of Acute Segmental Testicular Infarction

目的探讨急性睾丸节段性梗死的超声表现。方法回顾性分析10例临床诊断为睾丸节段性梗死患者的临床与超声影像资料,10例均行常规超声及超声造影检查。结果10例患者年龄为16-52岁,中位年龄为29岁。7例病灶位于左侧,3例位于右侧。灰阶超声上6例呈楔形,3例呈类圆形,1例呈不规则形;6例呈低回声,4例呈不均质中等回声。彩色多普勒图像8例病灶内无血流,2例少许血流;8例病灶周围血流增加。超声造影6例呈楔形,4例呈类圆形;8例病灶无强化,2例少许强化;10例病灶周围环状强化。结论急性睾丸节段性梗死好发于青年,以左侧多见。超声主要表现为睾丸内的楔形或类圆形的低回声或不均质中等回声病灶,大多数病灶内无血供,但周围睾丸实质可出现血流增加和环状强化。

Objective To explore the ultrasonographic findings of acute segmental testicular infarction.Methods The clinical data and ultrasound images of 10 patients with acute segmental testicular infarction were retrospectively analyzed.All the 10 patients underwent conventional ultrasound and contrast-enhanced ultrasound examinations.Results The 10 patients were aged from 16 to 52 years old,mean aged 29 years old.On conventional ultrasound,6 lesions were wedge shaped,3 were oval,and 1 was irregular shaped.Six lesions were low reflectivity and 4 were mixed reflectivity.Color doppler ultrasound showed 8 lesions were avascular,2 were hypo-vascular,and 8 had a perilesional enhancing rim.Contrast-enhanced ultrasound displayed 6 lesions were wedge shaped and 4 were oval.Eight lesions were avascular and 2 had intralesional vascular spots.All the 10 lesions had a perilesional enhancing rim.Conclusion Acute segmental testicular infarction occurs most commonly in young adults and more commonly involves the left side.The main ultrasound findings of acute segmental testicular infarction are that of a wedge or oval shaped,low reflectivity or mixed reflectivity lesion within the testis.On color doppler ultrasound and contrast-enhanced ultrasound,most of the lesions are avascular and surrounded by parenchyma with increased vascularization and have a perilesional rim of enhancement.
