Tubular ectasia of the epididymis
Tubular ectasia of the epididymis results in enlargement of the epididymis with multiple cystic interfaces. It typically occurs in those with a prior vasectomy but can be also seen with other causes of obstruction of the ductus deferens.
This can give a characteristic "speckled appearance" on ultrasound due to multiple interfaces between the epididymal tubule wall and fluid 2.
