The ultrasonography is a very useful diagnostic procedure in obstetric & gynecologic mass. so we anlayzedtotal 153 cases of pelvic ultrasonogram with pathologic diagnoses. The results were as follows: 1. The ages ofpatients were distributed from 16 to 70 years-old, and the third decade was the most prevalent. 2. Of 153 cases,the ovarian masses were 85 cases, the tubal ones were 49 cases, and the uterine were 19 cases. 3. Of 85 ovarianmasses, physiologic ovarian cysts were 44 cases, and cystic teratoma were 14 cases. Of 49 tubal masses, tubalpregnancies were 35 cases and the most prevalent. Of 19 uterine masses, leiomyomas were 11 ases and the mostprevalent. 4. Of 153 cases, the echo-complex masses were 103 cases, the cystic ones were 34 cases, and the solidones were 19 cases. 5. The characteristic findings of frequent masses were as follows: (1) The physiologic ovariancysts were 44 cases, and show mainly cytic or pure cystic masses in 42 cases. (2) The ectopic pregnancy were 36cases, and show echo-complex masses in 21 cases, and cul-de-sac fluid echo in 22 cases. (3) The cystic teratomaswere 1 cases, and reveal mainly cystic or pure cystic masses in 10 cases, and calcification with posterioracoustic shadowing in 6 cases. (4) The uterine leiomyoma were 11 cases, and reveal solid mass with abnormaluterine contour in 8 cases. (5) The malignant or borderline malignant lesions were 6 cases. (6) Of 153 cases, thepathologic diagnosis was possible in 98 cases(64.1%).

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.
