Prepubertal Ovarian Cyst Formation: 5 Years' Experience

Abstract

Small, unilocular ovarian cysts less than 1 cm in diameter are found in prepubertal females with a frequency of 2-5% and are clinically insignificant. Ovarian cysts greater than 2 cm are rare. Unilocular ovarian cysts less than 5 cm may be followed conservatively with ultrasound surveillance until regression, without a major risk of torsion. Ovarian cysts associated with precocious pseudopuberty are generally larger than 2 cm and may be recurrent.
