On examination of a male neonate, a hard, swollen scrotum that is bluish-red and does not transilluminate indicates which condition?

• A. Hydrocele
• B. Inguinal hernia
• C. Testicular torsion
• D. Epididymitis

Answer: (C)

A hard, swollen scrotum that is bluish-red and does not transilluminate is most consistent with testicular torsion. When the spermatic cord twists, venous outflow is blocked first, then arterial inflow becomes compromised, leading to rapid swelling, edema, hemorrhage, and ischemia of the testicle. Because this is a solid tissue problem rather than fluid, the scrotum doesn’t fill with fluid and won’t glow under light, which is why transillumination is absent. This helps distinguish it from fluid-filled conditions like a hydrocele, which would transilluminate. An inguinal hernia can cause scrotal swelling too, but it typically presents with a groin bulge and may be reducible, not the acutely hard, discolored, nontransilluminant testis pattern seen with torsion. Epididymitis is less likely in a neonate and usually presents with different signs and a more gradual course. Testicular torsion is an emergency requiring urgent surgical detorsion and fixation to salvage the testis, with time being a critical factor for viability.
