Malignant Brenner tumor with transition from benign to malignant components: computed tomographic and magnetic resonance imaging findings with pathological correlation.

摘要

We report computed tomographic and magnetic resonance findings of an ovarian malignant Brenner tumor with transition from benign to malignant components. The tumor was demonstrated as a cystic mass with solid mural components. The benign component contained dense calcifications on computed tomography and showed very low intensity on T2-weighted images, whereas the malignant component showed high intensity. The admixture of 2 components may well reflect the pathological feature and may be a diagnostic clue to malignant Brenner tumor.
