  • testicle - ~2 to 3 cm in width and 3 to 5 cm in length
  • epididymis - along the posterolateral aspect of each testis
  • vas deferens
  • spermatic cord
  • median raphe


  • linear transducer
  • scanned in longitudinal and transverse axis
  • first the unaffected hemiscrotum
  • coronal scan showing both testicles side by side (Buddy View) should be performed to identify differences in size and echogenicity, and vascularity
  • Power Doppler examination on unaffected side for calibration of machine


  • hyperemia:inflammation and demonstrates no flow and lots of color with out a pulse
    • Think orchitis and detorsed testicle

Findings and DDX

  • epididymitis - enlarged epididymis with decreased echogenicity
  • orchitis - enlarged testicle with heterogeneous echogenicity with increased blood flow
  • hydrocele - Abnormal collection of fluid in the space between the visceral and parietal layers of the tunica vaginalisin anterolateral portions
  • varicocele - left side, multiple anechoic serpiginous tubular or curvilinear structures of varying sizes (larger than 2 mm in diameter)
  • testicular torsion - power Doppler with absent blood flow in the affected testicle; patient can present early and still have flow
  • torsion of the testicular appendage
  • testicular trauma
  • herniation of abdominal contents into the scrotum - peristalsis of bowel
