Which condition is characterized by sudden severe unilateral testicular pain with a high-riding testis and absent cremasteric reflex?

• A. Epididymo-orchitis
• B. Testicular torsion
• C. Inguinal hernia
• D. Orchitis

Answer: (B)

Sudden, severe unilateral testicular pain with a high-riding testis and an absent cremasteric reflex is classic for testicular torsion. The twisting of the spermatic cord abrupt ly cuts off blood flow and often pulls the testicle upward, giving a high, horizontal lie. The cremasteric reflex is lost because the torsion disrupts the nerves that trigger the cremaster muscle’s contraction. This combination signals a surgical emergency where urgent detorsion and exploration are needed to save the testis; delays raise the risk of infarction.

Epididymo-orchitis tends to present with a more gradual onset of pain and swelling, often with fever or urinary symptoms, and the cremasteric reflex is usually preserved. Inguinal hernia presents with groin or scrotal swelling and a palpable hernia, not the acute torsion pattern. Orchitis is inflammatory and likewise lacks the abrupt high-riding testis and absent reflex characteristic of torsion.
