caption_attribution_description: 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).
context_page_description: Scrotal ultrasound is a medical ultrasound examination of the scrotum. It is used in the evaluation of testicular pain, and can help identify solid masses.
context_section_description: A scrotal hematocele is a collection of blood in the tunica vaginalis around the testicle. It can can follow trauma (such as a straddle injury) or can be a complication of surgery. It is often accompanied by testicular pain. It has been reported in patients with hemophilia and following catheterization of the femoral artery. If the diagnosis is not clinically evident, transillumination (with a penlight against the scrotum) will show a non-translucent fluid inside the scrotum. Ultrasound imaging may also be useful in confirming the diagnosis. In severe or non-resolving cases, surgical incision and drainage may be required. To prevent recurrence following surgical drainage, a drain may be left at the surgical site.
