To describe the gray-scale and color Doppler ultrasound features of uncommon (<5% prevalence) primary malignant ovarian tumors.
Retrospective analysis of 98 masses in 89 patients (median age: 50.4 years old, ranging from 15 to 81 years) diagnosed as having an uncommon primary ovarian malignancy. All patients had undergone transvaginal color Doppler ultrasound according to a standardized protocol prior to surgical tumor removal.
Ultrasound features analyzed were laterality, presence of ascites, tumor volume, morphologic appearance (unilocular, multilocular, unilocular-solid, multilocular-solid, and solid), and color Doppler score (subjective assessment of the amount of flow as absent, scanty, moderate, or abundant).
Pathological diagnoses included uncommon epithelial tumors (n = 59), germ cell tumors (n = 10), sex cord-stromal tumors (n = 11), sarcoma (n = 9), and lymphoma (n = 9). Germ cell tumors presented in younger women (p < 0.001). Germ cell tumors, sex cord-stromal tumors, sarcomas, and lymphomas were significantly more often solid as compared with epithelial malignancies, which appeared more frequently as complex (cystic-solid) tumors (p < 0.001). There were no differences in color Doppler score between the various types of tumors.
Germ cell tumors, sex cord-stromal tumors, sarcomas, and lymphomas tend to appear as unilateral solid tumors. Color Doppler score is not useful for discriminating among uncommon primary ovarian malignancies.
