- Undescended testicle
- Hydrocele
- Hydrocele of the spermatic cord
- Inguinal hernia
- Testicle trauma
- Testicle tumor
- Testicle metastasis
- Testicule torsion
- Varicocele
Approach to the differential diagnosis of scrotal mass:
- US is the first step in imaging
- An undescended testicle may make the contralateral side appear mass-like
- A cystic mass is most likely a hydrocele
- Inguinal hernias are diagnosed by observing bowel peristalsis, incarceration of an inguinal hernia cannot be diagnosed on US
- When assessing testicular trauma, assess the viability of the testicle
- Testicular torsion should be ruled out in all cases
- A solid testicular mass is a tumor until proven otherwise
- Varicocele has a classic serpiginous appearance
