A: Equally common on both sides, B: More common on left due to drainage into inferior vena cava, C: More common on left due to drainage into renal vein, D: More common on right due to drainage into inferior vena cava, E: More common on right due to drainage into renal vein,  <response>: This is a clinical vignette describing a patient with scrotal pain and an enlarged, non-transilluminating bag of worms felt on palpation.
