Rate and associations of epididymal cysts on pediatric scrotal ultrasound.

PURPOSE: We established the baseline occurrence of epididymal cysts, and the correlation between epididymal cysts and testicular size.

MATERIALS AND

METHODS

We retrospectively reviewed all pediatric scrotal ultrasounds done at our institution in 8 years. We analyzed the proportion of cysts by patient age and compared testicular size in boys with vs without epididymal cysts.

RESULTS

Of all patients 14.4% had epididymal cysts. The cyst incidence increased with age, ie 35.3% of boys older than 15 years had cysts. Boys with epididymal cysts had larger testes than boys without cysts regardless of side or age (p <0.001).

CONCLUSIONS

Epididymal cysts are more common in older boys. Boys with epididymal cysts had larger testes than boys without cysts.
