ABSTRACT
OBJECTIVE:
To compare the sonographic findings with pathological features of ovarian thecoma, and to analyze the relationship between them.METHODS:
The sonograms of 45 ovarian thecoma cases were reviewed retrospectively and categorized into three subtypes as sound attenuation pattern, homogeneous hypoechoic pattern and solid and cystic mixed pattern. The pathological findings were classified as theca cell-predominant, fibroblast-predominant and mixed thecoma according to the cellular composition of the tumors. Hyaline degeneration and luteinization of the tumors were recorded. The pathologic findings of each subtype based on sonography were compared.RESULTS:
Of the 45 patients, there were 34 (75.6%) solid ovarian lesions, 15 (33.3%) of those showed a sound-attenuation pattern with an anterior hypoechoic zone and posterior acoustic attenuation in sonography, the other 19 (42.2%) cases had homogeneous hypoechoic pattern with no posterior acoustic attenuation, and the remaining 11 (24.4%) cases presented as a solid and cystic mixed pattern. There were no significant differences in pathological cellular composition among the three sonographic subtypes. Five solid tumors containing hyaline degeneration and one with luteinization were found to have posterior acoustic attenuation. The solid and cystic mixed thecomas showed cystic degeneration and hemorrhage.CONCLUSION:
Solid ovarian thecomas usually have typical sonographic features, which may be associated with degeneration but not with cellular composition within the tumor.
