OBJECTIVE: To determine whether gray scale characteristics of the solid components of cystic ovarian teratomas exist that could differentiate more common benign forms from malignant variants. METHODS: We retrospectively reviewed the sonographic images of 188 ovarian teratomas that contain at least a 25% cystic component and correlated the images with the final diagnosis. Features of the solid component assessed included its echo texture, overall appearance, shape, size, and internal homogeneity. RESULTS: One-hundred seventy-seven teratomas were benign, and 11 were malignant; among the malignant masses, 7 were high grade. Of the benign forms, 155 solid components (88%) were hyperechoic, 168 (95%) were focal in appearance, 105 (59%) were nodular in shape, and 123 (69%) were uniformly solid. Of the malignant types, 9 solid components (82%) were isoechoic, 6 (55%) had branching, 6 (55%) were irregular in shape, and 8 (73%) were uniformly solid. Five malignant teratomas (45% overall and 71% of high-grade subtypes) had branching isoechoic components. Only 2 benign teratomas (1%) had isoechoic components that branched. CONCLUSIONS: The presence of a branching isoechoic component in a cystic ovarian teratoma may suggest malignancy.
