Insights
Most pediatric epididymal cysts resolve naturally over time with conservative management. Surgical intervention is rarely needed for these benign scrotal conditions in children.
Area of Science:
- Pediatric Urology
- Pediatric Surgery
- Diagnostic Imaging
Background:
- Epididymal cysts are common benign scrotal masses in children.
- Conservative management is often the initial approach.
Purpose of the Study:
- To review the outcomes of conservative management for pediatric epididymal cysts.
- To determine the natural history and resolution rates of these cysts.
Main Methods:
- Retrospective review of pediatric patients diagnosed with epididymal cysts between 1991 and 2002.
- Analysis of patient age, presentation, and time to cyst involution.
- Scrotal ultrasound confirmed all diagnoses.
Main Results:
- Twenty pediatric patients with epididymal cysts were identified.
- The average age was 10.5 years; common presentations included scrotal mass and pain.
- Ten cysts resolved spontaneously with an average regression time of 17 months; only one patient required surgery.
Conclusions:
- Pediatric epididymal cysts typically demonstrate spontaneous resolution with conservative management.
- Observation is a safe and effective strategy for most cases, minimizing the need for surgical intervention.
Purpose:
We reviewed the outcome of conservative management of epididymal cyst in children at our institution.
Materials And Methods:
We retrospectively reviewed the records of all patients with epididymal cyst from 1991 to 2002. Age and mode of presentation as well as time to complete involution of the cysts were studied. Diagnosis of epididymal cyst was confirmed by scrotal ultrasound in all cases.
Results:
A total of 20 patients were identified with epididymal cyst. Average patient age at presentation was 10.5 years. Fifteen patients presented with scrotal mass and 4 with scrotal pain. Cysts were between 3 and 30 mm. Only 1 patient required surgical excision due to persistent pain. Epididymal cysts resolved in 10 patients who completed followup. Average time to complete regression was 17 months. None of our patients had a history of exposure to diethylstilbestrol, cryptorchidism, cystic fibrosis or von Hippel-Lindau disease.
Conclusions:
Our findings imply that most epididymal cysts involute with time.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
