ABSTRACT
ultrasonography is very important in the diagnosis of various kinds of diseases in Obsterics and Gynecology.It has high diagnostic accuracy in the diagnosis of pelvic masses and widely used for the detection of normal orpathologic pregnancy. But still it is difficult to differenciate degenerated myoma, H-mole and missed abortion byultrasonography. So the authors analyzed the ultrasonographic findings of 81 patients with myoma(29 cases), H-mole(23 cases), and missed abortion(29 cases) and the results are as follows; 1. Diagnostic accuracy was 8.6% inmyoma, 87% in H-mole and 89% in missed abortion. 2. The most typical ultrasonographic finding of myoma waslobulated mass contour with nonhomogenous internal echo. 3. The most characteristic finding of H-mole was finevesicular pattern internal echo with globular enlargement of uterus. 4. The most frequent finding of missedabortion was deformed gestational sac with or without remained fetal echo. 5. Clinical correlation was veryimportant for accurate diagnosis, especially when differential diagnosis was very difficult between myoma withmarked cystic degeneration, missed abortion with large distorted gestational sac and H-mole with severedegeneration.
