neonatal ovarian cyst

congenital ovarian cyst; neonatal ovary cyst

Congenital ovarian cysts may be diagnosed in utero by ultrasound and are associated with resolution; however, their evolution is variable and may require intervention.

Complications such as torsion and rupture usually occur in cysts larger than 5 cm in diameter.

Functional ovary cysts

Cysts that develop in utero are most often lined by luteinized cells, whereas those in older children are more often lined by granulosa cells.

Premature infants born before the 30th week of gestation may have multiple follicular cysts associated with estradiol production.

These cysts are secondary to elevated follicle-stimulating hormone (FSH) and luteinizing hormone (LH) secretion, and they may be associated with relative insensitivity of the hypothalamus and anterior pituitary to negative feedback by estradiol.

Histologically, the neonatal cysts are mainly of follicular origin or necrosis made a diagnosis impossible.
