A CASE OF NONMETASTATIC TROPHOBLASTIC DISEASE FOLLOWED BY MAGNETIC-RESONANCE-IMAGING

The consecutive findings of the magnetic resonance (MR) imaging in a p atient with nonmetastatic trophoblastic disease are reported. On MR im age, there are noted two kinds of MR findings which suggest the existe nce of trophoblastic disease; one was a typical hypervascular mass of heterogeneous signal intensity within myometrium, and the other was th e increase in myometrial and parametrial flow void. The former finding appeared only for a short period while the disease was highly active. The latter finding well paralleled the serum human chorionic gonadotr opin (hCG) level, and the remarkable flow void, indicating dilatated b lood vessels, disappeared with the complete remission of the disease. These findings suggest that MR imaging may be useful for diagnosing an d following gestational trophoblastic disease.
