Gestational Trophoblastic Disease: A Multimodality Imaging Approach with Impact on Diagnosis and Management

Figure 10

Choriocarcinoma in a 22-year-old patient with extremely raised β-hCG levels, 3 months after an abortion. Axial T2-weighted MR image (a) reveals a heterogeneous, hyperintense mass in the right lateral myometrium with parametrial extension. Note is made of a relatively preserved endometrial cavity (arrowheads). Postchemotherapy follow-up MRI ((b), (c)) demonstrates interval regression of the trophoblastic tumor (arrows) with reduction in its size, heterogeneity, and signal hyperintensity on T2-weighted image (b). Hyperintense signal of the lesion (arrows) on T1-weighted image (c) indicates intralesional hemorrhage, a known occurrence following chemotherapy.
