English: Scrotal ultrasonography of a 58-year-old man with non-traumatic swelling of the left scrotum for a couple of weeks. It shows a hematocele, as a fluid volume with multiple thick septations. The hematocele displays no blood flow on Doppler ultrasonography. A pyocele has a similar appearance, but was excluded by lack of inflammation.
The testicle is pressed to the side (upper left in image).
