Which statement best differentiates testicular torsion from epididymitis in terms of age group and clinical features?

• A. Torsion occurs in younger males with abrupt severe pain and absent cremasteric reflex; epididymitis occurs in older patients or STI-associated with gradual onset, fever, and positive cremasteric reflex.
• B. Torsion occurs in older patients with gradual onset and fever; epididymitis occurs in younger with abrupt pain and absent cremasteric reflex.
• C. Torsion and epididymitis always present identically and require imaging to differentiate.
• D. Epididymitis never presents with fever.

Answer: (B)

The key idea is to use age and how the symptoms start to tell torsion from epididymitis. Testicular torsion most often hits younger males, especially adolescents, with a sudden, severe onset of testicular pain. The exam typically shows a high-riding, horizontally lying testis and a cremasteric reflex that’s absent on the affected side. This abrupt, dramatic presentation reflects an acute loss of blood flow to the testis and is a surgical emergency. Epididymitis, on the other hand, tends to occur in older patients or in sexually active younger men (often STI-related). The pain and swelling usually develop more gradually, and fever and urinary symptoms can be present. The cremasteric reflex is usually preserved in epididymitis, which helps distinguish it from torsion. So the statement that torsion occurs in younger males with abrupt severe pain and absent cremasteric reflex, while epididymitis occurs in older patients or STI-associated cases with gradual onset, fever, and a preserved cremasteric reflex, best differentiates the two conditions. If there’s uncertainty, color Doppler ultrasound can help by showing reduced or absent blood flow in torsion versus increased or normal flow with epididymitis.
