Struma ovarii in a 56-year-old woman – a case report

Introduction. Struma ovarii represents a rare tumor, only 1% of the ovarian tumors, with an incidence of 0.3-0.7%. The positive diagnosis is obtained by microscopic examination; sometimes elevated serum levels of thyroid hormone, CA 125 and ultrasound aspects can suggest the preoperative diagnosis....

Description
Summary:	Introduction. Struma ovarii represents a rare tumor, only 1% of the ovarian tumors, with an incidence of 0.3-0.7%. The positive diagnosis is obtained by microscopic examination; sometimes elevated serum levels of thyroid hormone, CA 125 and ultrasound aspects can suggest the preoperative diagnosis. Case presentation. We report the case of a 56-year-old woman with unilateral struma ovarii and no clinical or paraclinical evidence of the diagnosis to come. Transvaginal ultrasound revealed polyfibromatous uterus and apparently normal adnexa. Partial hysterectomy with bilateral salpingo-oophorectomy (considering the patients’ age) through laparotomy was performed under spinal anaesthesia. The histopathological result showed an endometrial polyp, multiple intrauterine leiomyomas, left ovary with thyroid follicles, which looked like normal thyroid tissue. The evolution of the patient was favorable, with no complications at the 6 months’ follow-up. Conclusions. In the literature, there are only a few cases of benign struma ovarium, and even less cases of malignant struma ovarium or bilateral presentation of the tumor. The particularity of the case consists in the diagnosis of struma ovarii only after surgery, in a patient without clinical or paraclinical evidence of this diagnosis.
