Learning objectives

- To identify normal anatomy and ultrasound (US) features of the male genitourinary system. - To define ultrasound findings of different acute scrotum and penile pathologies, as well as their most frequent complications. - To review the differential diagnoses in acute scrotal pain. - To discuss the utility of different imaging techniques (CT/MRI) beyond US.

Background

Acute testicular pain is a common cause of urological consultation of young adults in the emergency department, with a broad list of causes (e.g.: infectious, traumatic, vascular...). A quick and effective diagnosis is essential, as it can have great repercussions on the prognosis of the disease. US is the method of choice, being an innocuous test, easily available and highly sensitive in the hands of an expert radiologist. It is therefore essential to recognize the radiological signs of the main differential diagnoses. Nevertheless, on some...

Findings and procedure details

1) TESTIS AND SCROTUM - NORMAL SCROTAL US IMAGING: ( Fig. 1, Fig. 2, Fig. 3and Fig. 4) Testis and scrotum: A) Scrotal layers: Minimally hyperechogenic or isoechogenic compared to testis. Thickness B) Testis: Homogenous and intermediate echogenicity. C) Tunica albuginea: Echogenic rim surrounding the testis and gives rise to hypoechoic septa that extend deep into testicle dividing it into lobules. D) Tunica vaginalis parietal and visceral: The parietal and visceral layers are separated by physiological hydrocele. D) Mediastinum testis: Hyperechoic band extending in craniocaudal...

Conclusion

US is a fundamental tool in the diagnosis of acute male genitourinary pathology. It is essential that every radiologist who works in the emergency room be aware of the imaging appearances of acute scrotum and penile pathologies.
