Ultrasonographic and pathologic study of ovarian tumors

ABSTRACT

This is a retrospective study of 161 ovarian neoplasms, all of which were surgically removed and had preoperative sonographic examinations. They were evaluated respect to age, tumor size and its echogenicity. The results were as follows 1. Of all 161 tumors, physiologic lesions were 67 cases (41.6%), germ cell tumors were 28 cases (17.4%) and serous tumors were 19 cases (11.8%). 2. Of all 161 tumors, right ovarian lesions were 82 cases (50.9%), left were 59 cases (36.7%), and bilateral lesions were 20 cases(12.4%). 3. The most characteristic findings of tumors were as follows 1) Physiologic tumors were 2-9cm sized (88.1%), anechoice-5% echogenic (79.1%), and developed during 4th & 5th decades (91.0%). 2) Inflammatory tumors were 2-9cm sized (94.1%), 50%-totally echogenic (76.5%), and during 4th & 5th decades (94.1%). 3) Serous tumors were 2-9cm sized (60.3%), anechoic-5% echogenic (89.5%), and during 3rd & 4th decades (84.2%). 4) Mucinous tumors were 5-19 cm sized (77.8%), anechoic-5% echogenic (77.8%), during 2nd-8th decades with diffuse distribution. 5) Endometrioid tumors were 5-14cm sized (100.0%), variable echogenic, and during 3rd & 4th decades (90.9%). 6) Germ cell tumors were 5-14cm sized (75.0%), variable echogenic, during 3rd & 4th decades (82.1%). 7) Parovarian cysts were 2-14cm sized (90.0%), anechoic-5% echogenic (100.0%), with diffuse age distribution. 4. The malignant and borderline malignant tumors were 9 caseswith more than 10cm sized (77.8%), and developed during older than 4th decade (100.0%). Anechoic 3 cases, 1-5% echogenic 2 cases, and totally echogenic 4 cases were found.
