Radiation methods in the diagnosis of primary and recurrent malignant ovarian struma: A case report

Abstract

We provide a rare clinical and diagnostic observation of primary and recurring malignant ovarian struma. Malignant struma of the right ovary was detected 2 years after surgical treatment of primary benign struma of the left ovary. Six months later, the patient was diagnosed with a disease relapse, visualized exclusively according to radioisotope research methods. In the fourth year of anticancer treatment, ultrasonography revealed recurring foci along the peritoneum. According to the ultrasound data on the pelvic peritoneum and the projection of the removed right ovary, multiple solid nodes with high blood flow were visualized. Peak systolic velocity ranged from 2 to 9 cm/s in minor lesions from 4 to 12 mm, with an RI max of 0.53. For 4 years, the patient underwent radioiodine therapy with 131I with an activity of 6.0 GBq; the patients condition during the treatment was satisfactory.
