How is torsion of the appendix testis and epididymis diagnosed?

Our staff will examine your child and make a diagnosis based on a physical examination and history provided by the child or family member. Occasionally, examination of the scrotum reveals what looks like a small “blue dot.” This is the swollen, dying appendage of the testicle.
