Ovarian cystic masses are actually ovarian cysts. Ovarian cysts can be either physiological or pathological cysts. Ovarian cysts smaller than 5 cm may be follicular cysts or flavin cysts, which are physiological cysts and often do not require treatment, and the cysts will disappear on their own upon review after the end of menstruation. Pathological cysts may be inflammatory cysts, due to chronic pelvic inflammatory disease and continuous inflammatory stimulation, resulting in the formation of fluid in the fallopian tubes or encapsulated fluid in the ovaries, usually antibiotics can eliminate inflammatory ovarian cysts, if treatment with antibiotics is not effective, surgery may also be required. In addition, ovarian cysts may be teratomas or ovarian chocolate cysts, or they may be malignant cysts. Once an ovarian cyst is found, tumor markers need to be tested and further pelvic CT or pelvic MRI is needed to determine the nature of the cyst.
