The sonographic features of testicular appendiceal torsion include a circular mass with variable echogenicity located adjacent to the testis or epididymis [Fig. 30], reactive hydrocele and skin thickening of the scrotum is common, increased peripheral vascular flow may be found around the testicular appendage on color Doppler ultrasound.
Testicular torsion is a surgical emergency that requires immediate intervention to restore the flow of blood to the testicle. [3] If treated either manually or surgically within six hours, there is a high chance (approximately 90%) of saving the testicle.
Doppler ultrasound in a retrospective study was shown to be helpful for differential diagnosis of patients with acute scrotum. [13] Accuracy of imaging studies is higher for the differential diagnosis of testicular torsion and epididmo-orchitis, which there can still be the possibility of misdiagnosis for hematoceles due to testicular torsion. [13]
Testicle: an infarction of a testicle is commonly caused by testicular torsion and may require removal of the affected testicle(s) if not undone by surgery quickly enough. [14] Ultrasound of segmental testicular infarction. Infarct area shown as hypoechoic and avascular upper segment of R testis.
According to Prehn's sign, the physical lifting of the testicles relieves the pain of epididymitis but not pain caused by testicular torsion. [ 4 ] Negative Prehn's sign indicates no pain relief with lifting the affected testicle, which points towards testicular torsion which is a surgical emergency and must be relieved within 6 hours.
Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'. The contents of the abdominal cavity may protrude into the inguinal canal, producing an indirect inguinal hernia
Today, Doppler ultrasound is a common test: it can demonstrate areas of blood flow and can distinguish clearly between epididymitis and torsion. However, as torsion and other sources of testicular pain can often be determined by palpation alone, some studies have suggested that the only real benefit of an ultrasound is to assure the person that ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
