2022年11月15日 · Epididymal lesions are most commonly encountered on ultrasonography. Most epididymal lesions are benign; malignant lesions are rare. Benign solid lesions. adenomatoid tumor of the scrotum: most common epididymal mass 4. epididymal leiomyoma. papillary cystadenoma of the epididymis. sperm granulomas / post-vasectomy granuloma. sarcoidosis ...

2024年10月8日 · Ultrasound. See article: Testicular and scrotal ultrasound. The normal epididymis is iso-to-hyperechoic to the testes, with equal or less vascularity on color and spectral Doppler. The head of the epididymis is visualized superior and lateral to the testes, while the body and the tail are smaller with variable locations 2. MRI

2017年9月30日 · The appendix testis, appendix epididymis, and ectasia of the rete tubules can be visualized during the scrotal ultrasound and their characteristic appearance should be kept in mind to avoid confusion of these structures with testicular and extratesticular masses.

Ultrasonography is the ideal noninvasive imaging modality for evaluation of scrotal abnormalities. It is capable of differentiating the most important etiologies of acute scrotal pain and swelling, including epididymitis and testicular torsion, and ...

2024年7月19日 · Testicular and scrotal ultrasound is the primary modality for imaging most of the male reproductive system. It is relatively quick, relatively inexpensive, can be correlated quickly with the patient's signs and symptoms, and, most importantly, does not employ ionizing radiation.

Ultrasonography (USG) has been shown to be an excellent gold-standard diagnostic technique for a variety of scrotal diseases and disorders. It offers 100% sensitivity in diagnosis and can discriminate a range of disorders affecting the testis, epididymis, and scrotum with comparable clinical symptoms because of its great spatial resolution.

2022年4月8日 · Absent flow is seen in the spermatic cord on color and spectral Doppler imaging (not shown). Mass-like appearance of the enlarged epididymis (E) and inflamed scrotal fat at the level of the torsion (M) are characteristic findings seen in spermatic cord torsion.

1984年4月1日 · Ultrasound has been used to study focal cystic and solid lesions of the epididymis as well as inflammatory processes. Correlation with pathology has yielded a clearer understanding of the sonographic findings and aided in the evaluation of disease.

The main components when assessing the scrotum with ultrasound are the epididymis, testis, pampiniform plexus, spermatic cord and groin. The spermatic cord contains the testicular, cremasteric, and deferential arteries, vas deferens, pampiniform plexus, nerves, and lymphatics. Scrotal/testicular ultrasound longitudinal scan plane.
