Overview
Ovarian struma is a rare tumour classified as an ovarian teratoma. Most metastatic ovarian strumas consist of papillary or follicular carcinoma. We present a unique case of the patient with ovarian struma and peritoneal strumosis. The 58-year-old woman was followed up with the symptomatic hyperthyroidism of unclear aetiology, which persisted even after total thyroidectomy. Following a series of the imaging studies and a lymph node biopsy, a well-differentiated follicular carcinoma was identified, arising from additionally detected ovarian struma. Whole-body scintigraphy using 99mTc-sodium pertechnetate detected multiple radiopharmaceutical foci in the abdominal cavity, corresponding to the thyroid tissue supporting the suspected ovarian struma. The patient underwent debulking surgery with hysterectomy and bilateral adnexectomy and further extirpation of tumorous foci in the abdominal cavity. Histological examination confirmed dissemination of well-differentiated follicular neoplasm with a follicular variant of the papillary thyroid carcinoma. 131I therapy was performed, followed by diagnostic and post-therapeutic scintigraphy using 131I.
