Figure 5b. Intratesticular hematoma in a patient with continued scrotal swelling 1 year after blunt trauma. (a) Transverse US image of the scrotum demonstrates a normal-sized right testis (RT) surrounded by fluid, with a large complex cystic mass in place of the left testis. (b) Transverse view obtained with power Doppler imaging in the region of the left testis shows a complex fluid-filled mass with dimensions of 12.1 x 11.2 cm and with multiple septa. No normal parenchyma is identifiable in the left testis, and there is no visible flow, findings indicative of replacement of the entire testis by a hematoma.
