Testicular torsion is when a testicle twists on its spermatic cord, cutting off blood supply and threatening the testicle's survival.
Sudden, severe, one-sided testicular pain, often with nausea, vomiting, and a high-riding or swollen testicle. Pain can radiate to the lower abdomen.
Imaging confirms the twist, shows whether the testicle still has blood flow, and helps separate torsion from other causes of acute testicular pain.
Scrotal ultrasound with Doppler is the first test; absent or markedly reduced blood flow to the testicle confirms torsion.
Treatment is urgent surgical exploration to untwist the testicle and stitch both testicles in place to prevent recurrence; if the testicle is no longer viable, it is removed.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
