A young male presents with direct trauma to the testicle. Ultrasound shows a large collection of fluid in the scrotum with echogenic debris. What is the most likely diagnosis?

Bleeding into the scrotal space after direct trauma forms a hematocele. On ultrasound this shows as a fluid collection around the testicle that contains echogenic debris from clotted blood, rather than a simple clear fluid. This echogenic content distinguishes it from a hydrocele, which is a clear, anechoic fluid, and from spermatic or epididymal cysts, which are cystic structures arising from the epididymis and typically lack such clotted debris. If there’s concern for broader testicular injury, Doppler can assess blood flow to the testis, guiding management.
