● Cystic follicle is a cyst smaller than 3 cm lined by an inner layer of granulosa cells and an outer layer of theca interna cells; if 3 cm or larger then it is called a follicular cyst
● If the lining granulosa and theca cells show extensive luteinization, it is called a cystic corpus luteum when smaller than 3 cm or corpus luteum cyst when 3 cm or larger
● A surface epithelial inclusion is a cyst smaller than 1 cm lined by a single layer of ovarian surface epithelium; if 1 cm or larger then it is called a serous cystadenoma
● Cystic granulosa cell tumor, endometriosis and rete ovarii cyst may also enter the differential diagnosis of a small, ovarian cyst
