Abstract

n in 93 of the 112 tumors (83.0%), with pure cystic masses (types I-III) accounted for the remaining 19 tumors (17.1 %). Of the 112 tumors, 68 (67.1%) showed posterior sonic shadowing which was demonstrated only in the hyperechoic area of types IV-VI.
CONCLUSION
Any adnexal masses representing a hyperechoic area within a cyst, solid and cystic tumors containing hyperechogenicity or diffusely hyperechoic mass, especially when accompanied by posterior sonic shadowing, should be suspected as indicative of mature cystic teratoma.
