Ovarian cysts: the cause of ovarian cysts is not clear, liquid echoes are mostly considered as physiological ovarian cysts, usually after menstruation can disappear by itself, usually the patient does not have any special discomfort, and occasionally there is a hidden pain in the lower abdomen, distension and other discomforts. 2. Tubal effusion: If the patient is combined with gynecological inflammatory diseases such as salpingitis and pelvic inflammatory disease, due to the increase of inflammatory exudate, localized encapsulated effusion can be formed, and the patient will have abdominal pain, fever, vaginal secretion increase and other discomforts. For patients with 39mm*34mm fluid echoes in the right adnexal area, it is recommended that they go to the gynecology department of a regular hospital, complete the blood routine, tumor markers and other relevant examinations, and then take active treatment under the guidance of the doctor after clarifying the cause of the disease.
