Struma ovarii (SO) refers to a type of monoblastic mature teratoma composed entirely or mainly of thyroid tissue, accounting for 1%-3% of all teratomas and 0. 3%-1. 0% of all ovarian tumors. At present, there is no complete diagnosis and treatment guide for the diagnosis and treatment of this disease, and the clinical misdiagnosis rate is very high, and the diagnosis is mainly based on clinicopathological diagnosis. The patient was a postmenopausal woman who underwent total hysterectomy combined with bilateral adannexectomy. The postoperative pathology was consistent with goiter, and CA125 decreased rapidly and ascites disappeared. Through case reports and literature review, it is hoped that clinicians can enhance their understanding of this disease and improve their diagnosis and treatment level.
