Clinical significance of hysterography in the diagnosis of choriocarcinoma and invasive mole.

From 1963 through 1988, a total of 194 hysterographies were performed for 111 patients. Three types of abnormalities were observed on the hysterogram: filling defect, intramural invasion of the uterine wall by the contrast medium; and intravasation of the contrast medium into the pelvic veins. The pathology and clinical significance of three types of abnormalities were studied. The results showed that hysterography demonstrated better images than pelvic arteriography and B-scan for the diagnosis of choriocarcinoma and invasive mole, especially when combined with B-scan/or pelvic arteriography, a greater accuracy was achieved.
