Exploration of this acutely swollen testis in a 13-year old found it to be engorged and hemorrhagic. Torsion of the testis is caused by faulty fixation of the testis to the scrotum—the result of a redundant tunica vaginalis—and is a surgical emergency. The testis is untwisted and fixed to the scrotum. A contralateral orchiopexy is also typically performed.
