epididymal calcification
Epididymal calcification can be seen on ultrasound as hyperechoic foci within the epididymal head. If the calcifications are large enough, then they may demonstrate acoustic shadowing.
Differential diagnosis
- chronic epididymitis, e.g. bacterial, granulomatous (TB) or genital filariasis
- trauma: incidence of 34% in extreme mountain bikers and 8% in equestrians
- calcium/phosphate metabolism abnormalities: e.g. secondary to haemodialysis
