Ovarian serous borderline tumors are usually found in women of reproductive age and perimenopausal women. Therefore, the issue of preserving the reproductive and hormonal functions is highly relevant. We analyzed specific ultrasonic characteristics of ovarian serous borderline tumors by comparing preoperative ultrasound and postoperative morphological findings in 98 patients. Ultrasonography is an effective method of patient monitoring after conservative and ultraconservative surgeries for ovarian serous borderline tumors.

High rate of diagnostic and treatment mistakes leads to late diagnosis, metastatic appearance, resistance to chemotherapy, poor prognosis. Aim. To demonstrate possibilities of 18F-FDG PET/CT to find resistant lesions of gestational trophoblastic neoplasias. In the article, we analyze several medical reports to illustrate advantages of 18F-FDG PET/CT for evaluation of resistant gestational trophoblastic neoplasias.
