Фолликулярная киста яичника
Ovarian cysts are fluid-filled sacs within the ovary. The most common types are functional follicular cysts, corpus luteum cysts, and theca lutein cysts, which all develop as part of the menstrual cycle and are usually harmless and resolve on their own. Nonfunctional cysts include chocolate cysts, which are related to endometriosis, dermoid cysts, cystadenomas, and malignant cysts (a type of ovarian cancer). All types can be diagnosed via pelvic ultrasound. While ovarian cysts are usually asymptomatic, complications due to rupture of a cyst can occur and may require treatment. Moreover, individuals with ovarian cysts are at increased risk of ovarian torsion, which requires surgical correction.
