Discussion of Hydrocele
- Hydroceles are predominantly anechoic fluid collections that occur in the potential space between the two layers of the tunica vaginalis and/or along the spermatic cord.
- The most common cause of painless scrotal swelling in children.
- In the normal scrotum, 1–2 mL of serous fluid may be observed in the potential tunica vaginalis cavity and should not be mistaken for hydrocele.
- Virtually all hydroceles are congenital in neonates and infants and associated with a patent processus vaginalis, which allows peritoneal fluid to enter the scrotal sac.
- In older children and adolescents, hydroceles are usually acquired and are the result of an inflammatory process, testicular torsion, trauma, or a tumor.
 Imaging Findings for Hydrocele
- Anechoic fluid collection surrounding the anterolateral aspects of the testis and sometimes extending to the inguinal canal
