For cystic mass in the left adnexal region with a diameter of more than 5cm, gynecologists can fix the localized mass through double or triple diagnosis, and then it can be palpated in the abdomen, and some patients may be accompanied by localized pressure and pain when the doctor palpates it. For the left adnexal cystic mass with a diameter of more than 5cm, when the patient is thin, it is easy to touch the localized mass in the abdomen, and in severe cases, the patient may show abdominal distension or localized protruding mass. For the left adnexal cystic mass with a diameter of less than 3cm, it is not easy to be detected by internal examination or from the abdomen, and it is mostly found under gynecological ultrasound. For patients with cystic mass in the left adnexal region, it is recommended that they go to the gynecology department of a regular hospital for consultation and active treatment under the guidance of the doctor after the cause of the disease is clarified.
