Struma ovarii

Malignant struma ovarii is a rare tumor. This is a report of case of 45 year old female patient who was coming for a routine control at gynecology serv ice of Saint Pierre clinic of Ottignies. During the check-visit, a left –attached pelvic mass was obser ved. The mass was confirmed at the abdominal ultrasound scan and magnetic resonance imaging scan . It was found localized at the left ovary. Follicular variant of papillary carcinoma type of m alignant struma ovarii was diagnosed after a total radical hysterectomy and an omentectomy were done. Among two critical treatments that are classically proposed in such cases, a thyroidectomy followed by a 131 iodine radiotherapeutic ablation was found to be effective. Thyroxin suppre ssive treatments followed by biological and clinical assessments were applied. They were found to be effective since the patient had a positive evolution.

We present a case of a 40-yr-old woman diagnosed with a primary malignant struma ovarii. The patient was admitted with the complaint of pelvic pain and a large pelvic mass in the mid-portion of lower abdomen on gynecological examination. Pre-operative tumor markers and routine biochemistry were unremarkable. She was treated with total abdominal hysterectomy and right salpingo-oopherectomy. Post-operatively, she was diagnosed with a malignant struma ovarii through the usage of histopathological criteria similar to the guidelines for primary thyroid gland disease. The patient was subsequently performed left salpingo-oopherectomy and retroperitoneal pelvic lympadenectomy for re-staging. Although, left ovary and lymph nodes were histopathologically normal, she was offered thyroidectomy but she refused to accept the offer. Thyroglobulin level was monitored in the post-operative period. She is free of the disease for 18 months.
