Ultrasonographic findings of ovarian tumors

ABSTRACT

The ultrasound is easily available and noninvasive diagnostic method without radiation hazard. We can approachto differential diagnosis of ovarian tumors by gray sale ultrasound which can display the detailed structure ofsoft tissue. In department of radiology, Korea Veterans Hospital, 27 cases of histologically confiremd ovariantumors collected from March 1984 to February 1986 were analized. The results were as follows: 1. The agedistribution was from 13 to 72 years. 2. The histologic diagnosis of ovarian tumors(27 cases) are as follows:teratoma(14), mucinous cystadenoma(8), mucinous cystadenocarcinoma(1), serous cystadenoma (2), Krukenburg tumor(1)and malignant thecoma (1). 3. The long diameter of ovarian tumors ranges from 4cm to 28cm. In these, mucinouscystadenoma is the largest and their size are as follows; less than 10cm; 25%, 11–15 cm; 12%, 16–20 cm; 25% andmore than 20cm; 38%. 4. The ultrasonographic findings of teratoma(14) were mainly cystic (8) or echogenic(6).There were echogenic solid components showing distal acoustic shadowing or fat-fluid level within cystic masses.Echogenecity of solid masses was heterogenous. 5. The ultrasonographic findings of mucinous cystadenoma&cystadenocarcinoma(9) were unilocular cystic (3) or multilocular cystic(6). There were variable amount ofechogenic component within cystic masses. 6. Those of serous cystadenoma(2) were unilocular cystic (1) ormultilocular cystic (1). 7. Krukenburg tumor(1) and Malignant thecoma(1) were heterogenously echogenic.
