In clinical practice, some women with ovarian teratoma may not exhibit any symptoms and the presence of an ovarian teratoma might only be discovered during a physical examination. In some cases, women with ovarian teratoma may experience torsion of the tumor after vigorous activity. When torsion occurs, the patient may suddenly feel pain in one side of the lower abdomen, accompanied by nausea and vomiting. If these symptoms occur, it is necessary to seek immediate medical attention and, if necessary, undergo timely surgical treatment.
