Ultrasonographic features and CA125 levels of hormonally active ovarian tumors.
Subjective ultrasonographic assessment is currently considered to be the best method of differentiation between various types of ovarian tumors. The aim of the study was to evaluate selected ultrasonographic features and CA125 levels of hormonally active ovarian tumors.



A total of 1135 women with ovarian tumors were diagnosed between 2006 and 2014 at the Division of Gynecologic Surgery, Poznan University of Medical Sciences. Within these tumors, there were 60 hormone-secreting ovarian tumors, including: 20 granulosa cell tumors, 28 fibrothecomas, 10 dysgerminomas, 2 struma ovarii, and 9 metastatic ovarian tumors. The tumors were evaluated by ultrasonography according to the International Ovarian Tumor Analysis group criteria. Additionally, we evaluated serum CA125 levels in all patients.



Granulosa cell tumors occurred most frequently as large unilocular-solid cysts, moderately to highly vascularized, with low-resistance vascularization. Dysgerminomas were predominantly large unilocular-solid cysts or purely solid tumors, with minimal to moderate low-resistance vascularization. Fibrothecomas were solid masses with minimal, high-resistance vascularization. Struma ovarii occurred as small, solid masses with abundant, highresistance vascularization. Metastatic ovarian tumors presented mainly as multilocular-solid tumors with strong, low-resistance vascularization. Papillary projections were most frequently observed in metastatic tumors and granulosa cell tumors in 56% and 50% of the cases respectively, although only half of granulosa cell tumors papillary projections exceeded 3 mm. Elevated CA125 levels were found only in metastatic ovarian tumors.



Hormonally active ovarian tumors present several ultrasonographic features which may facilitate preoperative diagnosis.
