Summary

Small ovarian cysts are common in prepubertal females and usually harmless. Larger cysts are rare but may require monitoring for complications like torsion or precocious pseudopuberty.

Area of Science:

  • Pediatric Gynecology
  • Reproductive Endocrinology

Background:

  • Ovarian cysts are frequently encountered in pediatric patients.
  • Understanding the incidence and clinical significance of ovarian cysts in prepubertal females is crucial for appropriate management.

Purpose of the Study:

  • To determine the frequency of ovarian cyst formation in prepubertal females.
  • To analyze the clinical implications and outcomes of ovarian cysts in this age group.

Main Methods:

  • Retrospective chart review of prepubertal females diagnosed with ovarian cysts.
  • Analysis of ultrasound findings, cyst characteristics, and clinical presentations.

Main Results:

  • Ovarian cysts were identified in 99 of 1818 prepubertal females (5.4%).

  • The majority were small (2-3 mm), unilocular cysts (83%), with an incidence of 2-5% in females aged 0-8 years.
  • Large cysts (>2 cm) were rare, occurring mainly in infants; two of 17 large cysts were associated with torsion and complex ultrasound features.
  • Five cases (5%) of functioning cysts causing precocious pseudopuberty were identified.

    • Conclusions:

    • Small, unilocular ovarian cysts (<1 cm) are common (2-5%) and clinically insignificant in prepubertal girls.
    • Large ovarian cysts (>2 cm) are rare; unilocular cysts <5 cm can be managed conservatively with ultrasound surveillance.
    • Ovarian cysts linked to precocious pseudopuberty are typically larger (>2 cm) and may recur.
