How is scrotal transillumination performed?

• A. Use a cool light source in a dark room, pull scrotal wall tightly over the mass and shine light anteriorly from behind the scrotum
• B. Shine light anteriorly from behind the scrotum in daylight
• C. Use ultrasound to illuminate
• D. Use a heat lamp to illuminate

Answer: (A)

Transillumination checks whether a scrotal swelling is fluid-filled or solid by testing how well light passes through it. Fluid such as in a hydrocele allows light to transmit, so the scrotum glows, while solid tissue or a hernia tends to block light and show little to no glow. To perform it, do it in a dark room with a cool light source. Gently pull the scrotal wall taut over the mass to bring the area into the light’s path. Shine the light from behind the scrotum toward the anterior aspect. If you see a glow through the scrotum, that suggests a fluid-filled process like a hydrocele; little or no transillumination points toward a solid mass or other non-fluid cause, prompting further evaluation such as ultrasound.
