Scrotal haematocele

Last revised by Mostafa Elfeky on 6 May 2022

Scrotal haematoceles are collections of blood within the scrotal sac, but outside of the testis.

A haematocele normally results from trauma to the scrotum, or on occasion following surgery. Some think that a varicocele is a risk factor for developing a haematocele 4.

Ultrasound is usually the sole imaging modality used, typically being first line for those with a scrotal swelling or pain following trauma to the scrotum. Unlike a hydrocele, which is anechoic, a haematocele is of increased echogenicity and often has septa within. If the ultrasonographic investigation is performed right after the event, a fresh haematocele can appear anechoic, though some turbulence will occasionally be seen within it.

A clinical differential would be for a scrotal wall haematoma.
