If the cyst in the right adnexal area is an occupying lesion, it is important to distinguish between ovarian cysts and tubal cysts. If it is a tubal cyst, most of them are caused by fluid in the fallopian tube, and it is recommended to use broad-spectrum antibiotics together with metronidazole for anaerobic bacteria. If the cyst in the right adnexal area is a cyst on the ovary, it is important to distinguish whether it is a physiological cyst or a pathological cyst. If it is a physiological cyst, it is usually less than 5 cm in diameter and occurs mostly during the second half of menstruation and will shrink significantly or disappear after menstruation, so it can be treated without treatment. In case of pathological cysts, they often cause menstrual disorders or lower abdominal pain and are often larger than 5 cm in diameter and are treated clinically by surgery.
