Colour Doppler imaging--a new method to differentiate torsion of the spermatic cord and epididymo-orchitis.

A newborn boy with torsion of the spermatic cord and an 8-year-old boy with epididymitis were investigated by colour Doppler imaging (CDI). Due to torsion of the spermatic cord, no blood flow could be observed within the testis and the epididymis. In epididymitis blood flow was markedly increased. CDI seems to be useful for differentiating between the two disorders.
